Pairing Cab1 with Base3

@winrose46 posted:

My Base 3 is working well with my Cab2 handhelds as well as the Cab3 app with only a couple of minor isses.  However, my Cab 1 handhelds cab not pair with the Base3. Checking uTube videos it appears that the procedure is to depress the set button and while holding down the set button depress the number for the channel and a beep should be emitted from the handheld once it pairs.  I have tried all three of my Cab1's, changed channels on the Base3 and I can not get the Cab1's to pair with the Base3.  Anyone have an idea of what I am doing wrong?

Cab1L or Cab1?  Big difference.  Blue or Gray?

Cab1, the original TMCC handheld, does not work with the Base 3 unless I am mistaken.

Would it be possible to plug the TMCC base into the Base 3 to permit the original TMCC Cab1s to communicate with the base 3?

Yes, that's supposed to work.

The way I accomplished this:

The TMCC BASE1 is connected to a SER2 with a “Null Modem Cable”!  The SER2 is then connected to the New BASE3 with a PDI CABLE.  Now I can use a CAB1 to operate the Legacy & TMCC Engines !

Works  Great!!

I would refer you to a POST Dated 8/3/24 Titled:  BASE3 & TMCC/CAB1 Signaling Problem !!!

Concur with Fredstrains.

I purchased the null modem cable, SER 2, and a PDI cable and the Cab 1 works perfectly.

There you go ……

Thanks, I will order the cables.
