42 MDS TransNET Ref. Manual MDS 05-2708A01, Rev. E
In the USA, a maximum of four zones may be skipped for TransNET 900 and
a maximum of three zones may skipped for TransNET 2400. Check the regu-
latory requirements for your region. The
SKIP function may not be permitted
in your country and the radio will not respond to the
SKIP command.
SLEEP [ON, OFF]
Transceiver Sleep—Remotes Only
This command is used to set or display the radio’s Sleep Mode setting. The
default setting is
SLEEP OFF. When this setting is ON (enabled) the
Low-Power, or RTU-forced Sleep Mode, can be used. This function cannot
be turned on for a Master or Extension radio unless the unit is in the
Low-Power Mode. See “Using the Radio’s Sleep Mode (Remote Units Only)”
on Page 59 and “Low-Power Mode versus Remote’s Sleep Mode” on Page 62
for more information.
SREV
Firmware Revision Level
This command displays the version of the firmware currently loaded into the
transceiver.
