MCS-11 Connections
When MCS is selected to be placed on one of the three service channels and then RSS is
enabled and properly addressed, applicable ports on the controller module are enabled.
This allows the user to interface external MCS-11 Monitor and Control System equipment
at any or all four connectors on the backplane (J307, J308, J309, and J310). Two connec-
tors (J308 and J309) are synchronous, parallel, data ports and provide CLK outputs. Con-
nectors J307 and J310 are asynchronous ports.
For proper operation, MCS-11 must be provisioned using the following guidelines:
a.
MCS-11 must be selected as one of the service channels.
b. MCS must be assigned a valid address
c. The
MCS RSS
must be set to
ON
for each radio with a unique RSS address. Refer to
Appendix B on the attached CD for address details. At a site, typically only one RSS is
turned on. Station scanners at all other radios at that site are normally jumpered to the
RSS enabled radio to allow access to their detail scanners. If station scanners are prop-
erly wired, detail scanners always respond, regardless of whether RSS is provisioned
ON
or
OFF
.
