The SteppIR cable "K2" has Orion-Steppir connections: 2-2, 3-3, 5-5,
shell-shell, and pins 7-9 jumpered at SteppIR side. This accords with
the Steppir document at
http://www.steppir.com/pdf/serial%20interface%20operation.pdf .
However, I find that the Orion requires RTS (pin 7) high before it will
communicate. This is not the same as pin 7 on the Steppir side. A
jumper between pins 7 & 8 on the Orion side will connect RTS and CTS for
the Orion. This configuration works for me. (If I only had a nickle
for every time I came to grief with modem control signals...)
Steppir should know that the K2 cable is not sufficient for the stock Orion.

and it just wouldn't work. After a couple of conversations with Jim at
SteppIR, we decided that the pin connections were incorrect. They sent me
another cable, but I built one in the meanwhile.
The correct pin to pin connections are Pin 2 to Pin2, Pin5 to Pin5, Pin3
to Pin3, and Pin7 to Pin7? Pin 7 and Pin 9 must be jumpered at the SteppIR
Controller end. This worked for me and the cable that I later received also
worked.
I think if you make up a cable with these pin outs you will get the
interface to work.

Subject: [TenTec] Steppir vs Orion
Just got my SteppIR up yesterday. All is well, except...
Hooked the Orion serial port to the Steppir data in using
Steppir-supplied "K2" cable. Set everything up according to manual, I
think. No communication, despite power cycling, master reset, etc.
This is with firmware 1.371.
There was a lot of discussion a few months back about Orion/steppir.
One may be forgiven for naively thinking it should work out of the box
for current production.
Anyone know the scoop? TIA
