DCS remote programming port and TIU input?

The remote to TIU is a standard 4 conductor handset cord for a telephone. The cable between the phone and the handset.

It is required to upgrade the remote if needed. Otherwise it’s optional unless you have issues with the remote communicating with the TIU then it lets the remote communicate via the cable.

Thank you.

Hi MartyE,

I have 2 older corded phones with handsets and the connecting cables have 2 conductors.

The plugs on the ends do fit into the TIU and the remote.

I have 4 conductor cords but the plugs on the ends do not fit into the remote.

Are there adapters for my 4 conductor cords that will allow them to work with the remote?

Or, if I search on-line, how do I specify what I am looking for to make sure I get the correct size plug that will fit into the remote?

thanks

The 4-conductor cords that don't fit the remote are NOT handset cords.  Handset cords have the RJ9 plug, the ones that don't fit are most likely wall cords with the RJ11 plug.  Almost all the handset cords are coiled, so do a Google Search on telephone handset curly cord, and you'll find tons of choices.  Just make sure you get the cord with all four wires, a few only had two wires as you have discovered.

Got it.

Found one on Amazon that fits the description.

Thank you.

Just an FYI, I picked up a cable at Walmart over the weekend, ~4 bucks. I don't know what happened to my old one(probably thrown out), and I had two remotes to update from 4.1 to 6.1.
