There's a switch labeled "IRIG" which stands for Inter Range 
Instrumentation Group, and refers to a standard for 
telemetry encoding.  There is a standard for time code, a 
standard for modulating analog signas onto a bunch of FM 
carriers, and a standard for multiplexing several analog 
signals onto one FM carrier.

Apollo documents are probably VERY hard to come by these days.
