2.2 DESCRIPTION

The Model 1065 Industrial Short Range Modem operates 2-wire

(half duplex) or 4-wire (full or half duplex), in synchronous or asyn-

chronous modes, over unconditioned telephone lines. The Model 1065

supports bit rates up to 64.0 kbps. The Model 1065 operates in syn-

chronous mode between the local and remote modems; when connect-

ed to an asynchronous RS-232 device, the Model 1065 SRM converts

the asynchronous data to synchronous data.

The Model 1065 has several features to enhance overall perform-

ance: equalization, anti-streaming timer, transformer isolation to guard

against data loss due to ground potential differences, and Silicon

Avalanche Diode surge protection to guard against data line transients.

The Model 1065 features V.52 compliant bit error rate pattern tests

and two V.54 test modes: local analog loopback and remote digital

loopback. The operator at the local end may test both local and

remote modems, plus the line, in the digital loopback mode. Both RDL

and LAL modes can be controlled by a manual switch or via the

V.24/RS-232 interface.

3.0 CONFIGURATION OVERVIEW

The Model 1065 is fairly simple to install and is ruggedly designed

for excellent reliability: just set it and forget it. The following instruc-

tions will help you set up and install the Model 1065 properly.

3.1 CONFIGURATION SWITCHES

The Model 1065 uses 24 external mini DIP switches that allow

configuration to an extremely wide range of applications. These 24

DIP switches are grouped into three eight-switch sets, and are exter-

nally accessible from the underside of the unit (see Figure 1). Since all

configuration DIP switches are externally accessible, there is no need

to open the case for configuration.

The configuration switches allow you to select data rates, clocking

methods, V.52 & V.54 tests, word lengths, extended signaling rates,

async. or sync. mode, 2- or 4-wire operation, anti-stream control and

input impedance. The drawings, text and tables on the following pages

describe all switch locations, positions and functions.

3.4 CONFIGURATION SWITCH SET “S3”

The DIP switches on S3 set the anti-stream control, local loopback

enable, remote loopback enable and receive (input) impedance levels

for the Model 1065. Factory default positions of Switch S3 are shown

in the table below.

Switches S3-1 & S3-2: Input Impedance

The setting for Switches S3-1 and S3-2 determines the 1065

Series’ input impedance. This allows you to choose the optimum

impedance setting for your application. In long distance applications

the impedance of the cable must match the impedance of the load (or

resistor) of the Model 1065 Series unit. Thicker gauge cables requires

a lower Ohm setting, while a thinner gauge cable should receive a

higher Ohm setting. If you are using higher speeds you will need a

lower Ohm setting, and a higher Ohm setting for the slower speeds.

Refer to the table on the following page for assistance in selecting a

setting.

4.0 INSTALLATION

The Model 1065 operates in four twisted pair topologies:

2-wire/point-to-point, 2-wire/multipoint, 4-wire/point-to-point, and

4-wire/multipoint. In each of these topologies, the twisted pair wire

must be 19 - 26 AWG "dry", unconditioned metallic wire (see Appendix

C for wire recommendations). Dial-up analog circuits, such as those

used with a standard Hayes-type modem, are not acceptable. The

twisted pair may be shielded or unshielded. Both types yield favorable

results.

The Model 1065 offers an RJ-45 jack for its twisted pair line con-

nection. Figure 4 (below) shows the location of these interfaces on the

rear panel of the Model 1065 Series. Connect the wire to each Model

1065 Series as described in the instructions that follow the illustration.

The “+” and “-” indicators are for reference only.

4.1 TWO-WIRE INSTALLATION

When communicating over a single twisted pair circuit, the Model

1065 operates half duplex: that is, it transmits in only one direction at

a time. This method of operation is effective for both point-to-point and

multipoint applications.

In single pair point-to-point applications, you will need a pair of

Model 1065s for each circuit—one at each end of the single pair wire.

In single-pair multipoint applications you will need three or more Model

1065 units. These can be connected using a star topology, although a

daisy chain topology is usually used.

4.2 FOUR-WIRE INSTALLATION

When communicating over a two twisted pair circuit, the Model

1065 can operate full or half duplex, point-to-point or multipoint. In two

pair point-to-point applications, you will need a

pair

of Model 1065s for

each circuit—one at

each end

of the two pair cable. In two pair multi-

point applications you will need three or more Model 1065 units. These

can be connected using a star topology, although a daisy chain topolo-

gy is usually used.

4.3 FOUR-WIRE, MULTIPOINT INSTALLATION

Multipoint operation involves the connection of several terminals to

one host port. In such an application, one local Model 1065 is used as

a master unit, and it is connected to several remote Model 1065s that

are acting as slaves.

In a multipoint environment the master Model 1065 transmits con-

tinually. Initiation of two-way communication is RTS controlled by each

“slave” Model 1065 unit. To facilitate multipoint communication, the

master Model 1065 should have its carrier control DIP switch set to

“constantly ON” (S1-8=OFF). Each slave Model 1065 unit should have

its carrier control DIP switch set to “controlled by RTS” (S1-8=ON).

Figure 5 illustrates a typical Model 1065 multipoint application.

4.3.1 Multipoint Twisted Pair Connection

The Model 1065 supports multipoint applications using a star topol-

ogy. Maximum distance between the units will vary based upon the

number of drops, data rate, wire gauge, etc. Call Patton Technical

Support for specific distance estimates. Figures 5 and 6 show how to

wire the one-pair and two-pair cables properly for a Model star topolo-

gy. Note that the ground connection is not needed.

5.0 OPERATION

Once you have configured each Model 1065 Series unit properly

and connected the twisted pair and RS-232 cables (see Section 4.0),

you are ready to operate the units. This section describes reading the

LED status monitors, powering-up and using the built-in V.52 and V.54

test modes.

5.1 LED STATUS MONITORS

The Model 1065 Series features seven front panel status LEDs that

indicate the condition of the modem and communication link. Figure 5

shows the front panel location of each LED. Following Figure 6 is a

description of each LED's function.

5.1.1 The “TD” and “RD” Indicators

The Power LED glows green to signal power present. The “TD” and

“RD” indicators blink green with data activity. Off indicates a low RS-

232 logic level, green indicates a high RS-232 logic level. Note: RS-

232 devices idle in a

low

state, so the LED will be off if the connections

are correct and the RS-232 device is in an idle state.

5.1.2 The “RTS” and “CD” Indicators

The “RTS” and “CD” indicators are monocolor and will be off for a

“low” signal or green for a “high” signal. RTS lights for an incoming

signal on RS-232 pin 4. CD lights for an incoming signal on the line

side, and the resulting output signal on RS-232 pin 8.

5.1.3 The “Test” Indicator

The yellow“Test” LED indicates that V.52 or V.54 tests are running.

5.1.4 The “Error” Indicators

The “Error” indicator LED has two functions:

A. When the 1065 unit is in test mode (green “Test” LED is lit), the

error LED glows red when bit errors occur.

B. When not in test mode (green “Test” LED is off), the error LED

is used to indicate an RTS streaming condition. (See Section 5.2) for

information on the anti-streaming circuitry.

5.2 ANTI-STREAMING ERROR INDICATOR

When not in test mode (green “Test” LED is off), the front panel

“Error” LED is used to indicate a streaming error. When the Model

1065s’ anti-streaming circuitry is enabled, the RTS signal from the DTE

is timer controlled. The timer begins to count when the DTE raises

RTS. If the time period that RTS remains high exceeds the preset time

out period, the anti-stream circuit will force RTS low. The “Error” LED

will light red, indicating a streaming condition (RTS continually on).

This feature prevents a malfunctioning terminal from tying-up a com-

puter port in a multi-drop or polling environment. When the DTE drops

RTS, the anti-streaming timer is automatically reset and the front panel

“Error” LED turns off. The time out period is DIP switch selectable for

12.5 or 50 seconds.
