AT~P5

to switch from Point-to-Point operation mode to Multiple-to-One operation
mode. User can switch back to Point-to-Point operation mode using
AT~P1 command.

AT&!Y

The system current configuration setting dump.
“station xxxxxxx, channel x, active_flag xx, pkt recvd xx,
rxAlarm T"
This stands for “Remote station xxxxxxx is on channel"x", is
activated or de-activated, and the number of packets from
REMOTE STATION is received by MONITOR. "rxAlarm"
indicates if MONITOR unit has received any thing from that
remote unit in the past 30 seconds.

Step 2 :

Monitor Station operation setting and related AT Command sets are :

AT~M

to switch WINC 900A into MONITOR STATION mode

AT~Rxxxxxxx,n

to register all eight units running under channel n.

"xxxxxxx" is the 7 digit address of slave units. "n" is the channel
that REMOTE STATION uses for broadcast.

AT~Z

clears all registered REMOTE STATIONS from MONITOR
STATION’s memory.

AT~Cxx

Defines the channel scanning rule in the MONITOR. The "xx"

value can be in the range specified as follows.

0 -- channel 0, 1, 2, 3, 4, 5, 6, 7 1 -- channel 0 only (925 MHz)
2 -- channel 1 only (922 MHz) 3 -- channel 2 only (919 MHz)
4 -- channel 3 only (916 MHz) 5 -- channel 4 only (913 MHz)
6 -- channel 5 only (910 MHz) 7 -- channel 6 only (907 MHz)
8 -- channel 7 only (904 MHz) 9 -- channel 0, 1, 2, 3 (non-GSM)
10 -- channel 4, 5, 6, 7 11 -- channel 0, 2, 4, 6
12 -- channel 1, 3, 5, 7 13 -- channel 0, 2
14 -- channel 4, 6 15 -- channel 1, 3
16 -- channel 5, 7

Step 3 :

Remote Station operation setting and related AT Command sets are :

AT~S

Switch the WINC 900A from the MONITOR mode back to
the REMOTE STATION mode

AT\Cn

To define the channel used by this REMOTE STATION. If
multiple REMOTE STATIONs are configured to use the same

channel, collision avoidance is applied to achieve the best
performance.

+++

one (1) second guard time is required between “+”.
The Escape Sequence switches the unit from on-line broadcast

data mode to command mode such that AT commands can be

issued.

AT&!O

This switches the unit back to on-line broadcast mode.
