Command to disable competing RS-232 ports (1) or allow
competing RS-232 ports (0, the default). When a serial port
receives the g1 command, the remaining ports will be inhib-
ited from future access to the Network Terminal or thepumps
and will reply with either the I or J reply, indicating they are
inhibited from responding. Querying the command will
result in a return of 0 for no lockout present, and a code of 1,
2, or 3 for a lockout and indication of which port has owner-
ship.

Command to query, turn ON or turn OFF the full rough
coordination feature. When ON, all pumps sharing a com-
mon manifold will rough out to base pressure at the same
time assuming they were set into regeneration through the
group REGEN function (REGEN 99).
NOTE: This feature exists only in some custom Network
Terminals.

Command to query, turn ON or turn OFF the Power Fail
Coordination Feature. Upon recovery from a power failure,
all cryopumps sharing a common manifold will rough out to
base pressure at the same time assuming that both Full
Rough Coordination and Power Fail Coordination were
turned ON.
NOTE: This feature only exists in some custom Network
Terminals.
