Monitor and Control Modules

MCMs are a general purpose Micro-controller based card which provides 16 TTL Control O/Ps and can monitor upto 64 analog signals. These MCMs are the interface to all the settable GMRT subsystems, like the front ends, the LOs the attenuators etc. In detail, at each antenna, MCM 5 is the interface to the front end system, while MCMs 2,3, and 9 are the interface to the LO and IF systems.

The Feed Positioning System (FPS) which is used to position the feed turret so that the desired feed is at focus is also controlled by the ANTCOM.
