R1225 and echostation

Postby DFD1126 » Tue Jun 20, 2017 6:07 pm

I recently acquired a GR400 UHF repeater (contains an r1225) that I intend to use with GMRS. I also have a Rigblaster Pro that I want to use to interface the repeater to my computer so I can use Echostation as a repeater controller. I haven't ever tried to set anything like this up before so I wanted to see if anyone had tried something similar to this and could give me any pointers. I've played around with Echostation and have a pretty good understanding of how to get it going so I guess my biggest questuon has to do with using the RigBlaster and the r1225. I assume that the radio uses the same pin out for the mic connector that most of the Motorola radios do so I correctly configured the jumpers in the RigBlaster but I am still unsure of the best way to set everything up as there are so many options. Any pointers would be appreciated. This is just a project that I've been wanting to do for a while to have some fun with. Thanks in advance for any help.

What radios do you own?: 2 turntables and a microphone

Interfacing is done through the 16-pin connector in the back of the R1225. The pinout is the same as any other 16-pin Maxtrac/GM300 radio.

COR defaults to active low but can be changed to active high in programming. COR, PTT, and the audio lines all share a common ground.
When exposed to Rapid Fire Growth or Thermal Emergency, two things are lost:
1. Ability to use fine motor skills
2. Presence of mind
