2.3.4.1. Video Test Points

The Video test points are fully programmable from the « CONFIG » window (refer to the MCS User's Manual and
the TCP/IP Interface Specification, Global Table) for monitoring any baseband signal:

Note 1: Active (5 V) during FSK or PSK modulation or transmission of an Execute or pseudo-earth pulse.
Note 2: Set to 5 V at the beginning of the ranging sequence (transmission of first tone). Drops to 0 V at:
