4.0 Register/Command Reference
Values (dBm)
S124 RSSI from Downlink (dBm)
-120 to –20dBm (max reading)
This register displays the average signal strength received over the
previous 8 hop intervals from a Slave/Repeater. The value in this
register is also reflected in status lines RSSI1, 2, and 3.
Values (dBm)
-120 to –20dBm (max reading)
S123 RSSI from Uplink (dBm)
This register displays the average signal strength received over the
previous 8 hop intervals from a Master/Repeater. The value in this
register is also reflected in status lines RSSI1, 2, and 3, which connect
to the modem’s RSSI LEDs.
The ‘ATS123 /?’ command will show the RSSI statistics (min, max, average, channel, frequency).
The ‘ATS124 /?’ command will show the RSSI statistics (min, max, average, channel, frequency).
Values
0 - Point to Multipoint (PMP)
1 - Point to Point (PP)
2 - Peer to Peer or Everyone to
Everyone.
3 - Reserved
4 - PMP with acks
S133 Network Type
This register defines the type of network being deployed. This register
must be set to the same value on every unit in the system.
Point to Multipoint
- The Master broadcasts data to all units, and all
remote units send data back to the Master.
Point to Point
- Point to point traffic between a Master and a Slave
(with 0 or more Repeaters in between).
Peer-to-Peer
involves either communication between 2 (typically
remote) units (P2P) or between all units (Everyone-2-Everyone - E2E).
Values
S130 No Sync Intake
0 -
Disabled
1 - Enabled
Defines if the modem will accept data when/if the remote has become
unsynchronized from the Master. If set to 0, this function will be
disabled and any data received will be ignored. If set to 1, the modem
will accept data and buffer it until the unit is synchronized.
Values
S139 Compatible_21 at 345
0 - Disabled
1 - Enabled
If this register is set the P2400 will be compatible with the MHX2421
operating at a link rate of 345kbps.
