I am trying to load a program via RS232 and the controller is having a problem reading.

I am also getting an Alarm SR820. Can anyone tell me what this alarm code means?

[Jim-MFGNetworks]

Could you tell us a little more like cable config pin outs and software your using for communications I think the alarm is a DR off alarm (data set ready) I don't have a book with me but it will be in your book. Also check the port number and parameters on the machine.

[brourke]

We are using a basic 25-pin serial straight though. And yes it is a DR Off alarm.
We are using Master Cam to send program via COM1 on a PCMCIA serial card.

Not sure about the parameters in the controller.

First you cant use a straight though cable you need a NULL modem cable or adapter if it is 25 to 25 pin you can also make your own I could give you the pin outs if your going to make it. is this a 25 to 25 no 9 pin adapter at the laptop?

[brourke]

Yes, it is a 25 pin to 25 pin. What would be the pinouts for this cable? I will make a cable from scratch to make sure that is not an issue.

25 pin machine 25 pin PC

2 to 3
3 to 2
4 to 5
5 to 4 you can also jumper 4&5
6 6,8&20 pumper at the machine
8
20

if you jumper 4&5 you can't use hardware handshaking must XON/XOFF

[Jim-MFGNetworks]

Also when you get your cable up try punching a program out from the machine first and tell me what you get.

[brourke]

I will try that and get back to you. Thank you for your help so far.

[Jim-MFGNetworks]

I forgot about pin 7
pin 7 to pin 7

sorry
