Set Transceiver Mode
Sets modem operation as either base station or remote. Default is remote.
Set Default Handle
Sets handle number between 1 and 62 inclusive for a remote. This handle will override
the automatic handle assignment by the base station. This command can be used in
applications where it is desired to have specific modems have specific handles. When
specified for the base, the default handle determines which remote it will address when
transparent protocol mode is in effect. When

Enable Global Network Mode
For networks with multiple base stations, remotes are ordinarily only able to link to one
base station, set by the hopping pattern. Mode 1 enables the global mode that allows
remotes to link to any base station they can hear, acquiring whatever hop pattern is
required. In this mode a remote can only change base stations once it is no longer
registered with a base station.

Set Lockout Key
Allows further network segregation beyond the network number. This feature allows
multiple co-located networks in which global roaming is enabled. In global roaming, a
remote is allowed to link to any base regardless of the network number as long as the
lockout key agrees. By using different lockout keys, the bases to which remotes link can
be limited or segregated.
Set Hopping Pattern
The WIT2410 has 64 preprogrammed hopping patterns (also referred to as network
numbers). By using different hopping patterns, nearby or co-located networks can avoid
interfering with each other’s transmissions. Even if both networks tried to use the same
frequency, on the next hop they would be at different frequencies.
Set Transmit Power
The WIT2410 has two preset transmit power levels, 10mW (10dBm) and 63mW
(18dBm). Control of the transmit power is provided through this command. Default is
63mW.
Read Receive Signal Strength Indicator (RSSI)
This command reports the relative signal strength averaged over the last 10 hops. This
command returns a one byte value that is proportional to received signal strength and can
range from

This command reports the relative signal strength averaged over the last 10 hops. This

range from

30H
to
80H
where the lower the
number the lower the received signal strength and the higher the number the higher the
received signal strength. This is a relative indication and does not directly correspond to
a field strength number. This is available only at the remotes as the base station is the
only source that transmits on a regular basis. Plus, in a point-to-multipoint network the
base will receive different signal strengths from each remote.
