The 1747-C13 cable can also connect the interface module’s DH485 port directly to
a single SLC controller or fixed controller. It connects the DH485 port on the
module to the DH485 port on the SLC 500 controller.

Apply Power to Your DH485/RS-232C Module
Once you have installed your DH485/RS-232C interface module in your SLC 500
system, you are already to apply power to your SLC 500 system.
Battery Replacement, Handling, Storage, and Transportation
(Cat. No. 1747-BA)
Your module provides back-up power for RAM through a replaceable lithium
battery (cat. no. 1747-BA). This battery provides back-up for approximately five
years. A BAT LOW indicator on the front of the module alerts you when the battery
voltage has fallen below the replace battery threshold level.
