System information
Message format
This section describes the
messages exchanged between the
"GTC link" communication interface
and the external computer based
on the JBUS protocol.
The length of time after which a
message must be interpreted as
"not understood" depends on the
type of command sent.
The table opposite lists maximum
response times:

Sample commands
List of variable fields
(same for all cubicle types)
The binary data and binary
commands can be accessed bit or
word-wise.
The word address and position of
the bit in the word can be
determined from the bit address:
The binary data and binary
commands can be accessed bit or
word-wise.
The word address and position of
the bit in the word can be
determined from the bit address:
◗
hundreds and tens digit of bit
address = word address;
◗
least significant digit of bit
address = bit position.
