Astro tac to ATAC receiver

Postby kj4chv » Mon Aug 21, 2017 6:19 pm


I have seemed to lost my notes on how to locally/directly connect astro tac receivers to astro tac comparators. I had a RJ45 pin out somewhare. Was wondering if any one had one.

The cable is a cross over V.24 cable. When I get to work, I'll post the pinouts.

I found this in an old post from 2012 (the notes are mine.)

Code: Select all

Pin Signal      Color      Signal Pin
1---RX Clock----Orn/W----TX Clock---3
3---TX Clock----Orange---RX Clock---1

Use this for direct connections to an ASTROTAC. Connection to a router uses a straight-through cable.
Set clock to internal for direct connections (S101-1 off, S101-2 on) and external for connection to a router (opposite.)
When exposed to Rapid Fire Growth or Thermal Emergency, two things are lost:
1. Ability to use fine motor skills
2. Presence of mind
