Communication
Connections and Setup
RS-232 Communications
with an SLC 5/03, 5/04, 5/05
7–8
The DTAM Micro and RS-232 port of the SLC 5/03, 5/04, 5/05 must be set
as follows for communications to occur:
SLC 5/03
Channel 0
DTAM Micro
The DTAM Micro must have an application with AB DH485 operating
system installed. The Baud Rate and Parity of the DTAM Micro and the
SLC 5/03, 5/04, 5/05 must be set the same. We recommend you use 19200
baud, even parity, and 8 data bits to match the default settings of an
SLC controller.
SLC 5/03, 5/04, 5/05
Make sure that channel 0 is set up for DH-485 MASTER and the following
parameters match the DTAM Micro.
Parameter
Baud Rate
Node Address
Maximum Node
Address
Token Hold Factor
Diagnostic File Number
Parity
Data Bits
To provide maximum response times, we recommend that the DTAM Micro be set as node 0 and the
SLC channel 0 as node 1. Maximum node address should be 1. The connections are a completely
separate DH-485 network, you do not need to be concerned about duplicate node addresses from
another network.
