To provide maximum response times on point-to-point networks, we recommend that the DTAM
Micro be set as node 0 and the SLC as node 1. Maximum node address should be 1.
SLC 5/03, 5/04, 5/05 (channel 0) only supports EVEN parity.
The DTAM Micro RS-232 version has an RS-232 port and uses DH-485
protocol. The DTAM Micro RS-232 version can connect directly to the
MicroLogix 1000 using the 2707-NC10 cable. It can also connect to the
AIC+ module using the 2707-NC2 cable.
