Re: [TenTec] Steppir vs Orion

[Martin Ewing <martin@aa6e.net>]

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.

Cheers,
Martin, AA6E
