The equipment is classified in EN 60950 as a pluggable equipment class A for connection to the mains
supply, as such it is provided with mains inlet cords suitable for use in the country of operation. In normal
circumstances they will be of an adequate length for installation in the rack. If a mains cord proves to be
too short then any replacement must have a similar type fuse (if fitted) and be manufactured to similar
specification: check for HAR, BASEC or HOXXX-X ratings on the cable. The connector ends should be
marked with one of the following : BS1636A (UK free plug 13 amp); BSI, VDE, NF-USE, UL, CSA,
OVE, CEBEC, NEMKO, DEMKO, SETI, IMQ, SEV and KEMA-KEUR for the IEC 6 amp free socket.
Schuko and North American free plugs must have similar markings.
The installation of the equipment and the connection to the mains supply must be made in compliance to
local or national wiring regulations for a category II impulse over voltage installation. The positioning of
the equipment must be such that the mains supply socket outlet for the equipment should be near the
equipment and easily accessible or that there should be another suitable means of disconnection from the
mains supply.
The equipment is designed to operate from a TN type power supply system as specified in EN 60950. This
is a system that has separate earth, line and neutral conductors. The equipment is not designed to operate
with an IT power system, which has no direct connection to earth.

REAR PANEL CONNECTIONS
INTERFACE
Alarms, monitoring and control of the Converter units.
Note 1; these are INPUTs to control the front panel module online/ standby LED’s only for use with
external 1+1 switch units. If the internal 1+1 switch option is fitted then these pins are not connected.
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 MLA will be powered from the left hand mains input and the right hand MLA 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 MLA 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 MLA 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 (Option 6)
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 module interconnecting cables unless instructed otherwise.
REDUNDANCY WIRING WITH OFFLINE UNIT MONITORING (Option 6T)
An alternative to the above, the DLA200 can be purchased as a redundant system where the redundancy
switching is performed using transfer switches to allow the offline unit to be operated. In this
configuration the cabling is shown below.
Again, Peak Communications will supply the module interconnecting cables unless instructed
otherwise.

An internal connection change is required for changing from RS232 to RS485. Please ensure that 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.

Issue 1.15 DLA200 Dual Line Amplifier Unit Page 9
When the Ethernet option is fitted to the unit the user cannot change between RS232 or RS485, or baud
rate, however the address can still be changed. Changing the baud rate, which by default is 19200 on an
Ethernet enabled, unit will stop the Ethernet working properly!
MESSAGE FORMAT
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.
See table below.
[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 says. Extra information has been added
to show the PSU status information.

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

ETHERNET INTERFACE (Option 9)
If the DLA200 unit has been fitted with the Ethernet option the unit can be controlled via its in built web
page, TCP or SNMP.
Due to a lack of front panel on these units, it is not possible to display the IP address and other Ethernet
settings to the user easily. In order to discover the IP address and other Ethernet settings, initially only, the
Peak discovery windows programme needs to be run.
This software is available off the Peak website, when run it lists the units on the network, and allows the
user to view and modify, if necessary, the Ethernet settings to suit the user’s network.
The Configure IP settings button will bring up the following screen:
This allows the changing of the Ethernet settings, the initial password is "password", after the initial
settings change, it will change to “PEAKpass123”, and is case sensitive.
In order for the new settings to be used, the unit must be restarted by cycling the power.

Issue 1.15 DLA200 Dual Line Amplifier Unit Page 14
Webpage
The webpage is essentially split into two screens, Status and Configure, each one accessible via the links
part way down the screen. The webpage is displayed by entering the unit’s IP address into a normal web
browser.
TCP
The units can be controlled via TCP, this involves sending the normal RS232/485 commands to the unit
through a TCP port. The TCP port to be used is set by the user via one of the remote control interfaces.
SNMP
The units can be controlled via SNMP, the MIBS necessary for this are available from the Peak
Communications website. Please refer to the Peak-Agents.MIB file, as this shows which of the MIBS
available is used for the unit in question.
