1.2 Overview
1.3 Functions
MODBUS adaptor provides data communication between a UPS and a far terminal like a computer system.
The system provides a communication channel between RS485(PC side) and RS232(UPS side) interface
Note:
The MODBUS adaptor can be used with UPS models supporting TX301, TX300, and TX100 protocoles.
2 wires RS485 link is available

2. Installation
2.1 Configuration Of The Modbus Communication Parameters
The device takes the device number during power on please select device number from 1 to 255 by setting
device number dip switches
Where Dn is the nth dip switch. For example, if we need to set the device’s address to 183 then we need
to set 7th, 5th, 4th, 2nd, 1st, and 0th dip switch pins. The address is calculated using above equation as
follows:
2.2 RS232 Connection to UPS
Connect CC05 RS232 cable from serial port connector of the MODBUS adapter to the serial port of the
UPS.

2.3 RS485 Connection
Connect RS485 terminals of the MODBUS
adaptor to RS485 link
The internal MODBUS RS485 port
connection of the adaptor
0volt and +5 volt outputs are dedicated for
polarity resistors do not use this supply for other
purposes.
About Polarity
Normally the master of the network sets the polarity of the line (RP resistor 330 ohm ½ watt)
About termination
The two ends of the line must be terminated (RT resistor 150 ohm ½ watt)

2.4 Installation
Check RS232-UPS, and RS485 connections. If connections are OKAY, connect the power cord of the
MODBUS adapter to mains power (The power of the adapter must be supplied from UPS output
otherwise during line failure the power of the MODBUS adapter shutdown)
3. Operation
Turn on the UPS
During power up the MODBUS adaptor will check the UPS communication version if it supports the
version it will run.
The MDX2 MODBUS adaptor supports TX100, TX300 and TX301 UPS communication protocols.
For Test Purpose download MODBUS tester program from the link http://www.modbus.pl/modbus.htm
4. Indicator Lamp
The indicator lamps on the MODBUS adaptor shows the status of communication.
Indicator lamp functions
Lamp status Description
RS232 led (green) Always on Adaptor power on and UPS RS232 connection is lost
False status
RS232 led Regular Blink Adaptor is communicating with UPS
RS232 led Irregular blinking Adaptor do not support some UPS commands
MODBUS led (yellow) Always on Adaptor power on and MODBUS connection is lost
False status
MODBUS led Regular Blink Adaptor is communicating with MODBUS Network
ALARM led Always off
