Re: RS232

It asks you to send ASCII characters in HEX - so 'zone 1 on' would be:
50 43 5f 2a 31 31 0d

One thing I've found in the past is that some RS232 ports on aplliances can
be wired as RS232 DTE (opposite signal flow) and requires a crossover/null
modem cable - or crossover adapter.

Hi All

I'm getting all confused with RS232 on my Arcam AVR350 Amp. I'm trying
to send RS232 commands to it from my Pronto 9600 serial extender. The
extender software gives me two choice "ASCII" or "HEX".
Page 38 of the
manual details the RS232 settings but I'll be buggered if I can get them
to work but to be honest I'm not completely sure I understand the
document! http://www.arcam.co.uk/downloads/DiVA%20AVR350%20E.pdf

If any kind sole fancies taking a look at the manual and telling me what
strings and format I should be using for (say Zone 1 On and Off) I would
be very grateful.

I was going to try and test sending commands to the Amp via
HyperTerminal (if that program still exists) but soon realised that I no
longer have a PC with a serial port and can't find my USB to Serial
dongle anywhere!

Isn't it amazing how you can waste a Sunday afternoon!

TTFN

Rob
