Configuration
Before you use EM-BAC-MOD as a BACnet or Modbus
interface module, you have to configure it to the actual
application. To do so, use the switches on the interface
module.

①
Switch to select BACnet MS/TP or Modbus RTU
protocol
②
Switches to set the network addresses, 01-99
③
DIP switch to set communication parameters
Setting the protocol type
1.
Use the slide switch
①
to set the BACnet MS/TP
or Modbus RTU protocol.
Setting the network address
2.
Use the two address code switches X and Y
②
to
set a network address (01 to 99). Address 00 is
reserved for broadcast mode.
A maximum of 32 devices (network addresses)
can be operated on one network segment.
Cau-
tion:
a different network address must be set for
every device.
Setting the device family
3.
If the device is to be used with an EASYLAB/
TROX UNIVERSAL controller or a adapter module
TAM, use the DIP switch
③
to set switch S1 to
Off.
Communication parameters
4.
Use the DIP switch
③
to set the following parame-
ters:
S2 + S3 - Transmission speed EIA-485
S5 + S6 - Parity
S8
- Terminal resistor
Ask the responsible specialist consultant for the
values to be set.
