command name > x Description
S119
Quick Enter to
Command Mode
If this register is set to 1, a delay of 5 seconds is introduced at power-up before the
modem will go into Data Mode. If, during these 5 seconds, the user enters “mhx”
the modem will instead go into Command Mode and reply with “OK.” The terminal
baud rate must be set to 9600 bps. If you enter an incorrect character, the modem
will immediately go into Data mode.
The default setting is 0: The modem will promptly go into Data Mode upon
power-up.
Values:
0 disabled
1 enabled
S123
Average RSSI
This register displays (it is not a “setting”) the average signal strength received over
the previous 4 hop intervals. The value in this register is also reflected in status lines
RSSI1, 2, and 3, which connect to the modem’s front panel RSSI LEDs.
Values:
-110 to -55dBm (max. reading)
NOTE: A Master modem’s RSSI LEDs will not lighte until such time as it receives valid
packets from a “downstream” unit. Also, if the downstream unit(s) fail(s), a
Master will maintain the last RSSI reading display.
S130
No Sync Intake
Defines if the modem will accept data 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:
0
1
S133
Network Type
Defines the type of network (see Section 5.0 for a detailed description of network
topologies).
In a point-to-multipoint (PMP) network, the Master broadcasts data to all units, and
all remote units send their data (ultimately) to the Master.
A point-to-point (PTP) network involves 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-to-everyone —E2E).
Values:
0 Point-to-Multipoint
1 Point-to-Point
2 Peer-to-Peer or Everyone-to-Everyone
NOTE: ALL modems in a network must have the SAME value for Network Type.
