Communication Connections and Setup
6–8
The DTAM Plus and RS-232 port of the SLC 5/03, 5/04, 5/05 must be set as
follows for communications to occur:
RS-232C
DTAM Plus
Channel 0
SLC 5/03, 5/04, 5/05
Cable (Catalog No. 1747-CP3)
Gender
Adapter
RS-232 / RS-485 Versions
Gender Adapter Required
Comm Port
DTAM Plus
The DTAM Plus must have an application with AB DH485 operating system
installed. The Baud Rate and Parity of the DTAM Plus and the SLC 5/03,
5/04, 5/05 must be the same. We recommend you use 19200 baud, even
parity, and 8 data bits to match the default settings of an SLC 500
controller.
SLC 5/03, 5/04, 5/05
Make sure that the channel 0 port of the SLC controller is set for DH-485
MASTER using the following parameters.

To provide maximum response times, we recommend that the DTAM Plus be set as node 0 and the
SLC 500 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.
②
SLC 5/03, 5/04, 5/05 (channel 0) only support EVEN parity.
