Introduction
The PRL-1600C Pulse Radio Link is a Transmitter and Receiver system that wirelessly sends up to four channels of
KYZ pulses from the transmitter to a paired receiver. The short-hop PRL-1600C has a range of up to 5,000 feet
depending on site topography and solves the problem of getting pulses across parking lots, vacant lots, roads, railroad
tracks or other obstacles. With the PRL-1600C, you're now able to connect real-time KYZ pulses from 2 Form C pulse
channels or 4 Form A pulse channels. Pulses from each meter output are independently outputted on one of the four
channels in the receiver. The PRL-1600C eliminates trenching or other costly methods of getting wires strung between
each meter and the destination device as well as providing superior isolation against transients that could be induced in
a long cable run. Additionally, ground rise problems are eliminated since there is no electrical connection between the
two devices.
The PRL-1600C Radio Pulse Link system consists of one PRT-1600C Transmitter and one PRR-1600C Receiver. The
system uses Frequency Hopping Spread Spectrum (FHSS) technology to communicate on 64 frequencies between 902
to 927MHz, using one of 6 hop sequence "channels", and allows unlicensed operation by the user, allowing multiple
systems to operate in the same radio airspace. Nominally, the PRL-1600C will transmit pulses between 2,500 and
5,000 feet in an unobstructed line-of-sight configuration but may go farther depending on optimal site conditions.
PRT-1600C TRANSMITTER
The PRT-1600C Transmitter consists of the following:
*PRNT-1600C Pulse Radio Transmitter/Antenna Unit
*PRT-16C Pulse Transmitter Base Unit
The PRT-1600C Transmitter receives pulses from a meter's KYZ pulse initiator and sends them to the PRR-1600
Receiver unit wirelessly. Each 10 second interval, the number of pulses received from the meter's pulse KYZ initiator, is
transmitted to the Receiver upon the next transmission cycle. The Receiver will then generate the correct number of
pulses at KYZ outputs, over the next 10 seconds. The PRNT-1600C Transmitter/Antenna Unit contains the transceiver
radio, a microcontroller and all the circuitry and software to communicate with the Receiver. The PRT-16C Base Unit
contains the power supply, termination points, and has a built-in low voltage transformer-isolated power supply
generating a +13VDC sense (wetting) voltage. The sense voltage is connected to meter's dry-contact KYZ pulse
initiator. The PRT-1600 Transmitter is capable of operating on supply voltages of 120 or 208-277VAC. In addition to
line power, it can be operated with batteries or a solar power supply such as Solid State Instruments' SPS-1 Solar
Power Supply by using the PRT-16CS 12VDC Transmitter Base Unit. Transmitter boards are GREEN.
PRR-1600C RECEIVER
The PRR-1600 Receiver consists of the following:
*PRNR-1600C Pulse Radio Receiver/Antenna Unit
*PRR-16C Pulse Receiver Base Unit
The PRR-1600C contains the transceiver radio, a microcontroller and all the circuitry and software to receive pulses
from the Transmitter and output them on one of four output channels. The PRR-16C Base Unit contains the power
supply, output relays and termination points where all connections are made. Four output channels are available, and
can be configured as 4 Form A or 2 Form C. Each output channel contains one Form A (2-Wire) Solid State output. The
Receiver/Antenna unit is intended to be mounted outdoors, in a direct line-of-sight with the Transmitter/Antenna unit. It
cannot operate if obstructed by trees, metal poles, buildings or other objects. The Receiver Base Unit is designed to
mount indoors, or inside an existing control enclosure suitable for the application. The Base and Radio/Antenna Units
are connected together by means of an 8-conductor, #24AWG 4 twisted pair shielded control cable. It is important for
noise immunity and error-free communications between the Base and Transceiver that shielded control cable be used.
The PRR-1600 is capable of operating on supply voltages of 120VAC or 208-277VAC. Other power supply voltages are
available upon special order. Receiver boards are RED.

PRL-1600C SYSTEM DESIGN AND
PLANNING
Revision: 12/15/23
SYSTEM CONFIGURATION - The PRL-1600C can be used in one of two configurations: 4 Form A pulse
channels or 2 Form C pulse channels. The entire system operates in either one mode or the other. They
cannot be mixed.
Form A Configuration: The Form A configuration will transmit four 2-Wire (KY) pulse channels.
Form C Configuration: The Form C configuration will transmit two 3-wire (KYZ) pulse channels.
Determine the desired mode for the system.
Dip Switch DS1's switches #1 through #3 set the channel # or "hop" sequence. Both the PRT Transmitter and
the PRR Receiver units must be set to the same channel or hop sequence. See Table 1 at left.

SYSTEM CHANNEL - The PRL-1600C System operates on one of 6 hop sequence channels. Each channel
consists of 50 unique frequencies out of 64 frequencies available in the 902MHz to 927MHz range. This allows
enhanced reliability since RF transmissions are transmitted on one of the channel frequencies until they are
received by the receiver. Set the Transmitter and the Receiver to the same channel number. Multiple PRL-
1600C systems can operate in the same radio airspace by each system having a different channel number.
Once you have determined the channel # that you will use, configure Dip Switch S1's switches #1 through #3 on
the PRT-16C or 16CS Transmitter Base board and the PRT-16C Receiver Base board. Table 1 shows the dip
switch combinations for each channel.

SYSTEM OPERATING MODE - The PRL-1600C System operates in a near real-time operational mode, where
the PRT-1600C Transmitter transmits one transmission every 10 seconds with the pulse data it has received
from the meter over the previous 10-second period. When the transmission is received by the PRR-1600C
Receiver, pulses are generated over the next 10-second period. Additional error checking and pulse verification
are used in this mode for the highest possible accuracy. Packet Transmissions and Receptions are visually
indicated with LEDs on both base and radio/antenna units.

CONSIDERATIONS FOR A SUCCESSFUL
INSTALLATION
Revision: 1/1/24
GENERAL - The PRL-1600C System is designed to provide mirror-image pulses from the transmitter to the
receiver. This is important for Peak Demand Control since the KW demand is determined by timing the pulses. The
greater the time between pulses, the lower the demand. Conversely, the shorter time between pulses, the higher
the demand. Every effort is made in the PRL-1600C to be a "virtual copper wire" and make the pulses coming out
of the receiver the same pulse width as the pulses going into the transmitter.
The PRL-1600C System is designed for concentrated RF environments where there is a significant amount of RF
traffic on these or adjacent frequencies. Pulses are collected by the transmitter for 10 seconds. The number of
pulses received in the immediate 10-second period is then sent to the receiver which duplicates those pulses over
the next 10 seconds. All output pulses are thus delayed by 10 seconds. The benefit of this method is significantly
reduced RF traffic and high-accuracy due to the expanded error checking and pulse count "true up".
APPROPRIATE PULSE CONSTANT - It is important to properly program the Pulse Constant of the meter such that
there are no more than 2 pulses per second at the peak KW demand of the building or facility. Pulses faster than
this may be lost. If a high pulse rate is unavoidable from the meter and cannot be slowed down, consider one of the
DPR Dividing Pulse Relays (DPR-1, DPR-2 or DPR-4) from Solid State Instruments.
SHIELDED CONTROL CABLE - ***Shielded Control cable must be used between each radio and base unit.***
MINIMUM PULSE WIDTH - Make sure that the pulse width coming from the meter is at least 100mS in duration.
LINE OF SIGHT - Make sure that you have the Receiver Radio/Antenna Unit in a location where the Transmitter's
Radio/Antenna unit can "see" it with a wide field of view. The PRL-1600C is a Line-Of-Sight system, and the
transmitter must have uninterrupted and unrestricted sight with the receiver radio at all times. Make sure that there
are no trees, metal buildings, light poles, rail cars, trucks, buses or any other obstruction that gets in the line-of-sight
between the transmitter and receiver at any time. Interruptions in the line-of-sight may cause pulses to be lost.
Generally speaking, the PRL-1600C will not transmit through concrete, concrete block or masonry walls. We can't
stress this enough: The RF path must be line-of-sight!
HEIGHT - Mount the Transmitter and Receiver Radio/Antenna units up off the ground as high as reasonably
possible, 14' minimum, to eliminate RF reflections, improve reception and transmission distance. The higher the
transmitter is off the ground, the longer the transmission distance and the more reliable the reception by the
receiver.
MOUNTING: If mounting the Receiver Radio/Antenna unit on the side of a metal building, make sure that the
antenna in the Radio/Antenna unit is mounted at least 6.1" away from the metal siding. Use the mounting brackets
supplied with the PRL-1600C to get this distance. You may have to rotate the board to insure that the antenna is
not closer to the metal surface than 6.1", since the antenna is not exactly in the center of the board as well as the
board being mounted in an off-set fashion. If the antenna is closer than 6.1", the signal may be corrupted and
transmissions may be affected. Rotate each radio/antenna units' board if possible so the board is perpendicular to
the transmitter or receiver on the opposite end of the system, keeping the antenna 6.1" away from any metal.
INTERFERENCE - The PRL-1600C is a Frequency-Hopping Spread Spectrum system that communicates on 50 of
64 designated frequencies. It may or may not work in substations or in other areas where high-power energy and
magnetic fields exist, or where RF energy may jam the signal. The electromagnetic field around high voltage
conductors may cause enough interference so as to keep the system from transmitting correctly or may significantly
reduce the range of the system. It has been reported that other high-power RF transmitters mounted within close
proximity can jam or corrupt the signal even though they are not using the same frequencies.

PRNT-1600C PULSE RADIO TRANSMITTER
MOUNTING POSITION - (See Note Below on Cable Connection before mounting) The PRNT-1600C Transmitter/
Antenna unit should be mounted in an upright position so that the cable is located on the bottom of the unit. Mount
the unit as high as necessary to guarantee LINE-OF-SIGHT with the PRNR-1600C Receiver/Antenna unit. Mount
using the aluminum mounting bracket supplied, making sure that the center of the transmitter is at least 6.1" away
from any metal object such as a pole or metal building. Make sure that no metal mounting hardware is placed
above the bottom of the PRNT-1600C Transmitter/Antenna unit case.
CABLE CONNECTION TO PRNT-1600C - It is advisable that this task is performed, if possible, in a convenient,
clean work area before mounting the Transmitter unit. Connect the 8-conductor 24AWG(min) shielded control cable
to the 9-position connector on the PRNT-1600C Board. Access the PCB Assembly by unscrewing the Transmitter
housing cap on the bottom of the unit. Remove the Transmitter assembly from the housing. Feed the control cable
into the housing's weather-tight connector on the cap so that there is approximately 12" of cable through the cap.
Tighten the weather-tight cable fitting so that the cable is not quite tight and easily slides back and forth. Alternately,
non-metalic conduit ("Seal-Tight" or "Carflex") may be used to connect directly to the housing with 1/2" conduit
connectors and run the control cable to the Base unit inside this conduit.
Strip approximately 2" of the control cable's outer jacket to expose the individual conductors, being careful not to cut
the insulation of the conductors or any strands of the shield's drain wire. Strip the insulation of each conductor back
1/4". Connect each conductor of the cable to the 9-position connector TB1 using a small flat-blade screwdriver or
other similar tool to open the spring-loaded connector as shown above in Figure 2. Press down on connector lever,
slip wire into the hole and release. When all conductors are attached, attach a cable tie (ty-rap) through the
Transmitter PCB Assembly's holes and tighten the control cable down, leaving about 1/4" of jacket above the ty-rap
so as to provide adequate strain relief for the cable connections. Pull the cable back through the cap and weather-
tight connector and place the Transmitter PCB Assembly back into the cap's slots. Tighten the weather-tight
connector to secure the assembly in place. Put the ring spacer over the Cap's threads and insert the Transmitter
Assembly into the housing. Tighten the cap until spacer is tight. For best results, keep the length between the
Transmitter and the Base Unit to the minimum practical distance. When Transmitter installation is complete, secure
cap to mounting bracket using sheet metal screw in slot.

INSTRUCTION SHEET
PRT-16C BASE UNIT
Setting the System CHANNEL - Each system -- the Transmitter
and Receiver -- must operate on one of six different channels. A
"channel" is a collection of 50 specific frequencies that are arranged
in a specific "hop sequence". A unique channel allows multiple
systems to operate in the same radio airspace without any
interference with each other. Therefore, the transmitter and receiver
must be set to the same channel setting. The channel address is set
using a 3-bit binary code. See Table 1 below right for the list of
channels. Note that Channel #6 is the highest channel number and
even though there are eight unique switch combinations, Channel 6
is the highest channel that can be selected. The last two switch
combinations result in Channel #5 being selected.
Switch #4 - LED Timeouts - If enabled, UP, LED's 1-5 turn off after
10 minutes thus saving energy particularly in battery-powered
applications. Any Dip Switch change, re-enables LEDs for 10
minutes. If DOWN, the LED Timeout is disabled and LEDs 1-5
indicate status all the time.
Switch #5 - Not used.
Switch #6 - Not used
Switch #7 - Setting the Transmitter Input Mode - The PRL-1600C
can accept either Form C or Form A inputs. In the Form C (3-Wire)
mode, each input channel uses the K, Y and Z inputs. Two
independent 3-Wire meter pulse channels can be transmitted. In the
Form A (2-Wire) mode, each pulse channel uses the K (common)
and a Y input. Four independent 2-Wire meter pulse channels can
be transmitted. Set Switch #7 to the DOWN position for the Form A
mode and UP for Form C mode.
Switch #8 - Pairing the Transmitter and Receiver - The PRT-1600
System requires that each Transmitter and Receiver are paired
together. Each Transmitter must learn the address of the Receiver it
is designated to talk to. This makes it possible for the Transmitter to
only talk to the designated Receiver and ignore other devices
sending and receiving information on a particular frequency. After
installation is complete, perform the pairing procedure described on
page 17 ONLY IF the system has not been previously paired at the
factory. ***Do not switch #8 UP if the system is already
paired.***
