[Premium-Rx] Fw: computer control for RF 590 and WJ 8718

[Charles Hutton]

Per the data sheet at
http://www.rfcomm.harris.com/products/integrated-communications/rf-590a.pdf
, the 590A provides RS232, RS422 and MIL-188 interfaces. I had assumed all
are present but only 1 interface can be configured as active. Is that not
the case?

I'm glad my referral of ERGO (John Fallows) might have fruit. I think he's
the best answer for integrating a 590A controller into a stable, high
quality platform. He - as you can see from Don Nelson's email - is well
connected to the Premium Rx people and will make and test the product
correctly if there's enough interest.

By the way, 232 and 422 are not control languages. They do not specify the
meaning of bits or message content or message structure. They only specify
the physical layer (volts, current, timing, and some hardware handshaking).
We'll need Harris' definition of the data link and network layers where the
structure and content are defined. Hopefully that is readily accessible, but
this being a radio developed mostly for the military I'm a little nervous
that all the data isn't public.

  I was told the 590 requires HARP and the 590A will work with HARP or a
different 232/422 command language, but I'm not very sure. It may be
configuration or synthesizer dependent.

the R590A control codes. I'll bet they are nearly identical with 590. I've
also got a 590A to try :-)I've worked with John Fallows in the past to get
the 8712P and RX340 into ERGO4.Don NelsonOregon

      The proprietor of Ergo Software, an amateur radio operator, has
indicated he is willing to try incorporating support for these radios into
his software...if he can get the control protocols. I have both rx's, and
would want tooperate the WJ 8718 remotely via internet (located at a prime
rx site of course). The Ergo program looks interesting, and is priced very
reasonably. For a look:  http://www.swldx.com/ If anyone can furnish the
control codes, ( both of my rx's use the 422 standard ) we could send it to
Ergo. Fred     k2dx
