REMOTE 15 way D type RS232/485 serial interface. Configuration for baud rate and

addresses are set inside the unit as described later.

When the DLA200 has the Ethernet option (option 9), the 15 way D type connector is replaced by a

RJ45 ethernet connector.

POWER CONNECTIONS

The unit contains 2 redundant switch mode power supplies. The voltage input can be in the range of

100-240VAC. The unit is designed to work off both or one of the 2 feeds. In normal condition the Left

hand MBX will be powered from the left hand mains input and the right hand MBX will be powered

from the right hand mains inlet. Fault condition of only one mains input present will power both sides

from the single mains input

SLOT DESIGNATIONS

The Slots for the MBX units are designated Unit 1 and Unit 2, looking from the front of the unit the

RHS slot is for unit 1 and the LHS slot is for unit 2. This is also indicated on the rear panel.

When the MBX unit is slotted into position the external mounting screws must be fully tightened.

The slots are “hot swappable” and are capable of insertion / removal whilst the unit is powered.

REDUNDANCY WIRING

Where the DLA200 is purchased as a redundant system with two identical MLA modules the rear

panel cabling configuration is shown below.

The customer is required to supply the system input and output cables. Peak Communications will

supply the interconnecting cables unless instructed otherwise.

An internal connection change is required for changing from RS232 to RS485. For this ensure the unit

is switched off and the 12 cover screws are removed.

The jumper LK1 on the PCB needs to be set to the correct position in order to change between RS232

and RS485 operation. RS485 is towards the front of the unit, while RS232 is when the jumper is placed

towards the rear of the unit.

NOTE:

When the Ethernet option is fitted to the unit the user cannot change between RS232 or RS485,

however the baudrate and address can still be changed. If the baudrate is changed the internal settings

for the Moxa Ethernet board needs changing accordingly to match.

Issue 1.00 DLA200 Dual Line Amplifier Units Page 7

Remote control interfacing

The DLA200 dual block control system unit may be monitored and controlled remotely either via a

RS232 or a RS485 multidrop bus. The connection is made via the 15 way D type on the rear of the unit

and configured as described earlier.

The unit transmits and receives data serially in an asynchronous format using the standard ASCII

character set. The serial data consists of message frames composed of the following message characters:

STX, BYTE COUNT, DEVICE ADDRESS, INSTRUCTION, BODY, CHECKSUM, ETX. All

characters are compulsory except for the message body. The presence of a message body is determined by

the message type (INSTRUCTION). The total number of message characters in a message frame may

range from a minimum of 6 to a maximum of 255.

The remote control follows the following protocol: (in byte form)

[STX] start of message character #02.

[B] char defining how many characters are in the message including the STX & ETX parts.

[A] Address of unit. Address ranges from ASCI character 32 to 47. (configurable via dip

switches - see earlier

[I] Instruction number.

The possible instructions are:

STATUS REQUEST character 32

STATUS REPLY character 33

CONFIGURE character 34

[MESSAGE]

numerous characters from length 0 upwards. If no message present enter a 0.

[CHKSUM]

The checksum is used to verify the accuracy of the message frame. The checksum is defined as

the summation of all the bytes in the message, beginning with the 3rd byte (DEVICE

ADDRESS) and extending through the body of the message, ending with the last byte before the

checksum. The total of the bytes is then ANDed with 255 so that the checksum is truncated to a

single byte.

[ETX] End of transmission character #03

All message to and from the unit follow the above protocol with a character format of 8 data bits, one

stop bit, no parity, baud rate 300, 2400, 9600 or 19200. Note that all numeric values are shown as

decimal.

Message Information

The message protocol for this unit has been made to emulate the RCU100 units therefore the bands are

set as ‘A’ and ‘B’ not ‘1’ and ‘2’ as the metalwork/front panel say.

Status Request message:

In order to find out the STATUS of the unit a status request message must be sent.

STATUS REQUEST:

Instruction 32

Example for a Status Request to a unit that has been configured as address 32. The following

characters should be sent.

Issue 1.00 DLA200 Dual Line Amplifier Units Page 8

2, 6, 32, 32, 64, 3

This is explained as follows - character 2 is start of message, Character 6 denotes the message has 6

characters in total, Character 32 is instruction 32 (status request) character 64 is the checksum (32 plus

32 anded), Character 3 is end of message.

The unit would then reply with a STATUS REPLY message.

Status Reply message

This message tells the host computer the status of the unit.

Configure Message

This message is sent to the unit, when the host computer wishes to change which unit or units are to be

on line. When the message has been received by the unit a Status reply message will be sent back by

the unit.

The command will only change the state of the unit IF the unit is in REMOTE mode. The actual

position of the switch is overridden but the indicators on the front panel show the actual status.

Ethernet remote control (Optional – option 9)

The Ethernet option for the DBU series products adds the ability to control the unit by Ethernet instead

of by the standard RS232 or RS485, this is achieved via a separate module within the unit. This module

is supplied by MOXA and the part number is NE-4001T.

The command set for communication with the unit will be identical to the normal serial

communications, however knowledge of the selected transport protocol is required.

In order to use the Ethernet, the microprocessor in the Peak unit talks to the NE-4001T via its serial

port, this means a baud rate must be set up for talking between the NE-4001T and microprocessor. This

baud rate can be set to any desirable setting, as long as the NE-4001T board is setup similarly. The

factory default setting is 9600 baud.

The MOXA NE-4001T board can be located on a network using MOXA’s ‘Network Enabler

Administrator software’ which is available for free download from the ‘Documentation & Drivers’ link

on their website available on the following page:

http://www.moxa.com/product/NE-4100T.htm

Alternatively please contact Peak Communications for a copy.

When the NE-4001T board has been located on the network its settings can be configured to suit the

application needs.

SNMP Agent with MIB II & RS-232 Like Group.

The DBU series units fitted with Ethernet, have a built-in SNMP (Simple Network Management

Protocol) agent software.

It supports SNMP Trap, RFC1317 RS-232 like group and RFC 1213 MIB-II. The following tables list

the standard MIB-II groups, as well as the variable implementations for the units with Ethernet.
