How to tell which device is CAT and Logic-level

1

I have purchased two digirig mobiles, one for use on my TS2000, the other for use on my FTM-300. The TS-2000 uses an RS-232, and the FTM-300 uses the Logic-Level. How can one tell which mobile unit is the RS-232 and which one is the Logic-Level?

Logic levels configuration is default - the PCB will not have any solder joints on the back of the PCB. RS-232 will have three solder bridges on one side as shown here:

So the unit has to be opened up to inspect? Is there not some type of indicator on the exterior of the unit?

The recent units in the smaller case have grid:
[L|R|C|T|A]

No markings or marking on L indicate logic levels configuration
R - RS-232
C - CI-V
T - TX-500
A - attenuator activated

There are no indicators on earlier revisions.

Perfect! Very small, but I was able to locate them. Thank you!
