Astro Consolette Paging Encoder HELP!
Posted: Sat Feb 18, 2017 4:56 pm
Hi there,
I am in desperate need of assistance connecting a Zetron Model 15P Paging Encoder to an Astro Spectra Consolette.
I have the service manuals for both products, and have made several attempts at creating a DB25 pinout that will work, but have not had any luck. I will admit that I am completely winging alot of this, and have little experience working with creating custom cables to make things happen with the Spectras. I am hesitant to do much experimenting, because I do not want to risk damaging either the encoder or the consolette.
So here is where I am at:
On the paging encoder, I have several connections: +12-14VDC, system ground, audio out, and PTT (There are 3 possible connections for PTT: PTT Normally Open, PTT Common (which is jumped to the system ground), and PTT Normally Closed). I have tried using both PTT Normally Open and Normally Closed.
On the radio there are of course 25 pins on each accessory connector, I am focusing on connector 2 because it does not appear that connector 3 will work for what I need, but I don't know anything for sure.
I have power and ground figured out, those two were easy, and I know they are correct because the encoder powers up, and it would not if I missed one of those. I also have the audio correct, but not the PTT. I can send a page from the encoder, and if I manually key the radio with the desk mic, it will transmit the tones over the air, but I cannot get the encoder to make the radio key.
Please help!
