Command
08
1) MOBY U:
This command is recommended when scanning_time parameter is greater than 0 (standby time). Use
of this command optimizes the life of the MDS battery. An additional MDS command must now wait
for sleep_time of the MDS to expire again.
Antenna on/off
Table 3-13
Command
0A
Only for MOBY F/U/D:
This command is not needed for normal operation because, when a write/read device is
turned on, its antenna is always on.
The antennas must be turned off when two sensitive write/read devices are positioned very
close to each other. The application software must ensure that only one antenna is on at a
time.
