11.5 Telemetry/Addr List
Modbus, commonly used with telemetry devices, allows a connection via serial
port to the modem. Telemetry and Addr List commands are only used when the

List are available with all RLXIC Serial radios.

associated IP as the destination.
 n=0 : Disabled
 n=1 : Enabled
MVLEN=n
Modbus Variant ID Length: Length of the RTU ID in a Modbus-variant protocol, in
bytes.
 n=1 : This parameter is used to define the length of the RTU ID in Modbus-
like protocol data packets.
 n=2 : This parameter is used when the when the MD is set to hex 63.
MVMSK=hh
Modbus Variant ID Mask: Byte hex mask to use when extracting the ID. Specify
which bits in the ID field to use. This parameter is used when the when the Mode
Default (MD) is set to hex 63.
 hh=hex value
o 00 - no mask, all 8 bits (default)
o 0F - only the low order 4 bits
MVOFF=n
Modbus (variable mode) Offset: Indicates the offset in the data of where the
Modbus ID starts.
