Hi Dick,
Thanks for taking the time to help. I changed the statements as you suggested and that seemed to get me past the URL errors. But, of course, I now have new error messages. I've pasted copies below.

If I just run the script as rr.js I get the following error:

PS C:\users\dan\documents\rigrunner\chrr_b03> cscript rr.js
Microsoft (R) Windows Script Host Version 5.812

RR.JS Colin Haig's RIGrunner 4005i Control Script
[ERROR 7] Message:Object required. Status:200.
NOTE:If the error message above says The system cannot locate the resource specified, that may mean that the RIGrunner was unreachable or offline.
NOTE:This could be due to a network outage, bad URL, incorrect IP address, username or password.
Voltage Safe: false.


If I run the script like this: rr.js 1 1 1 1 1, which should turn on each of the nodes I get this message:

PS C:\users\dan\documents\rigrunner\chrr_b03> cscript rr.js 1 1 1 1 1

RR.JS Colin Haig's RIGrunner 4005i Control Script
[ERROR 3] Message:undefined. Status:undefined. Check the configuration settings.


The RigRunner is powered up and ready to turn on my equipment. Up to this point I've been accessing the RigRunner manually via MS Edge where the IP address brings up the RR window with no problem.

I'm sorry take up your time but I'm an absolute beginner with this stuff. I do really appreciate your help.
Thanks,
