Link Map
C200 (u) Set link map
The control system performs operations on port numbers 0…7. When we
refer to these ports they are “logical ports” which are normally mapped one-
for-one to the physical ports. This means that the RCB assigned a hardware
port number of 0 will map to logical port number 0.
With the link map you can assign any logical port to any physical port. In
normal operation, all logical ports are mapped to their corresponding
physical port. One example of why you may want to change the link map is
the case where you have two physical repeaters on a single control system.
One as a primary radio and one as a backup. Both can be plugged in at all
times. Lets say you have many custom macros written to operate on logical
port 0 which is assigned to physical port 0 and therefore the primary repeater.
If the primary repeater should fail, you could easily remap the backup
repeater on physical port 1 to behave as logical port 0. In this case, all
commands that would normally act upon the primary repeater is now going
to act upon the backup repeater with no other hardware or software
configuration changes.
This command sets the link map which maps the logical port number to the
physical port number.
Syntax is C200 p0 p1 p2 … D
p0 is the physical port number (0..7) that will be recognized as port 0
p1 is the physical port number recognized as port 1, etc.
Any ports not listed will be assigned in increasing order following the last
one specified. If there is a local repeater port, the first one should be logical
and physical port 0 - not absolutely required, some of the commands which
treat the lower numbered physical port which is a local radio as the primary
repeater port will may not send telemetry to the correct port if this is not
done.
