Timeslot Address
Frames can be formatted singly
(4 bytes per frame), or in a multi-
plexed mode whereby up to
8 GCI compatible devices can be
connected to the same bus. In the mul-
tiplexed mode, the frames of
4 bytes are transmitted in one of
8 timeslots - the mode and the timeslot
address of a particular GCI terminal
is set by means of strapping a code
on 3 device pins GCIM, AD0 to AD2
on the CODSP (see table 35). The
CODSP uses the GCI standard format
for analog terminals (see fig. 16).
