I will be sharing on this post the Tait TM8110 specifications including, pinouts, programming cable, model identification and much more. This is my first Tait radio so it took me a while to program it. clic here If you need to know how to program a Tait TM8110 radio.
This is a little commercial VHF/UHF radio. With 10 channels and 25 watts of RF Power it is a great radio for specific use cases.

As many commercial radios, the TAIT TM8110 also includes an emergency mode. This mode allows to activate different features on the radio and also activate other devices through the auxiliary port.
The radio allows for connection of an emergency switch to any input line to enter the emergency mode. If connected to the AUX GPI2 input line, the radio can also use ‘emergency power sense’ to power up the radio to enter the emergency mode
The radio also allows for output to external alert devices using the digital GPIO lines of the auxiliary connector and the internal options connector.
I will be publishing a post with information specifically on the auxilliary port.

Tait TM8110 Specifications – Model identification
Like many other radio brands, Tait uses submodels for a lot of their radios. Here you have a simple guide to identify your radio model.
Under the main body of the radio, you will find a label that includes information like this:
This is the label included on my radio.
You can read in the label that this is a VHF radio, now, let’s try to identify the rest of the model using the chart provided in the manual.
TMAB – Standard Name
1 – Identifies an analog radio
2- Identifies a 25 watts radio
B1- Identifies a VHF 136-174MHz radio
00- No options provided with the radio
Tait TM8110 specifications – Programming software and programming cable
To program this Tait Radio, you will need a programming cable and a programming software. You need to buy both, but if you have the skills you can build your own programing cable as I did.
TM8100 programming application, not a very creative name, but does what it is supposed to do. Unfortunately I don’t have a website to recommend where you can buy this software.
I’m using version 3.09 of the software without any issues on VHF and UHF radios.
