Hand-Held Radio Operation and Commands
The Sentinel Hand-held Radio can be used to access the Sentinel Satellite Unit. With the Sentinel Hand-held Radio,
you are able to turn on and off individual stations or clusters programs. During hand-held radio operation, the satellite
is placed in one of two satellite modes: Normal mode or Secure mode. In the Normal mode, all Sentinel satellites will
respond to the transmitted commands sent by the hand-held radio, regardless of the Satellite unit number. The Secure
mode, on the other hand, allows command transmission only to the specified unit. Therefore only the specified unit will
react to the commands.
Normal Mode - To place the satellite into Normal mode operation, send # # CCC # command where CCC is the
satellite’s unit code. Press the hand-held radio’s PTT button (Push To Talk) to transmit the command. Send # # to exit
Normal mode operation. Satellite displays
A while in Normal mode. Transmitted Normal mode commands will be
received by all Sentinel satellite operating in the Normal mode.
Command Operation
nn
Station nn (where nn is the specified station) will irrigate for 30
minutes. After 30 minutes, the station will stop irrigating and the
satellite waits for the next command.
nn h tt Station nn will irrigate until the specified hour (h) and minutes (tt)
expire. As an example, entering 12 1 30 will energize station 12 for
1 hour and 30 minutes.
nn nn nn Use this command to turn on multiple units for 30 minutes. The
desired Satellite stations are listed in series (nn nn nn). As an
example, entering 12 13 14 will energize stations 12—14
simultaneously.
3 Sending the 3 command will increment the currently operating station.
For example, if station 16 is currently in operation and the 3
command is transmitted, station 16 will stop and station 17 will initiate
operation.
1 Sending the 1 command will decrement the currently operating
station. For example, if station 16 is currently in operation and the
1
command is transmitted, station 16 will stop and station 15 will initiate
operation.
*
Send the
*
command to turn off the last station that was turned on.
If station 16 was the last station energized and
*
command was
transmitted, station 16 will stop operation.
nn
*
Send a
nn
*
command to turn-off individual stations. As an example,
to turn-off station 16 from a series of irrigating stations, send
a
16
*
command.
* *
To turn off multiple stations that are in operation within the same unit,
send a
* *
command. As an example, the satellite unit has stations
12–14 in operation. To turn-off all stations with one command,
send a
* *
command.
nn dd
*
Use this command to place a station in Rain OFF for a specified
number of days. Entering
16 05
*
command will disable
station 16 (
nn) for 5 (dd) days.
