Rx transfer switches. Like the ‘RED AUTO/MANUAL’ signal above, the
‘SWITCH CMD’ also has a corresponding REMOTE COMMAND,
“RTG=”. This command, defined in Appendix A, has the same effect as a
momentary short to ground on Pin V.

B.2.4 REDUNDANCY A/B

SIGNALS

Pin S on both J1 and J3 connectors are used to tell the CSAT’s that they are in a
redundant configuration.

B.2.5 REDUND_FLT

SIGNAL

Pin F on both J1 and J3 connectors are output signals from the RSU-5060 to the
CSAT’s to provide status indication to the CSAT’s regarding the operating
condition of both the RSU-5060 and the two transfer switches. This signal is
normally a one-half hertz square wave. If this signal goes away, the ONLINE
CSAT will use the AUXCOM (RS232) interface to the RSU-5060 to get more
information regarding the problem at hand. This information is available to the
user via the “RRS?” query described in section 4.

B.2.6 AUXCOM

SIGNALS

Pins H and J on both the J1 and J3 connectors are the EIA-232 RD and EIA-232
TD signals respectively. The AUXCOM interface is used solely in conjunction
with the RSU-5060, and should not be confused with the ‘Customers EIA232’
interface available on the CSAT J5 connector (pin E and F). The AUXCOM
interface is used by the ONLINE CSAT to ascertain information from the
OFFLINE CSAT as well as the RSU-5060.
