Networking Commands

LINK

The LINK command is responsible for configuring radio's operation mode.
It has parameters listed below.
Note: In parentheses is shown firmware version, which supports this parameter. If the
firmware version is not specified, it means that this parameter is supported in both ver-
sions.

sets/gets string type value representing the call sign of transceiver. The length of
CSIGN entered call sign can be less or equal to 10 characters. A-Z letters and 0-9 digits are
accepted.
sets/gets the compatibility with:
0 - Satel 3AS
CMPT

2 - Transmit Only
sets/gets the SNRM packet send option:
SNRM 0 - Off (default)
1 – On
Note: The frequency defined by CHAN parameter is not valid if Frequency Hoping mode
is selected. In the Frequency Hoping mode, the Frequency Pattern generator must gen-
erate the random numbers smaller than the number of frequencies listed in the unit's
