We are getting message "The request data address is Invalid" while forcing the output channel in test mode for STBDDO3705 module.
This message usually comes when STBNIP2311/STBNIP2212 module is configured at default IP address.
Once it set to Stored IP the issue will get resolved itself.
rotary switches set to Bootp - Test Mode ok
rotary switches set to DHCP - Test Mode ok
rotary switches set to Stored - Test Mode ok
'Test Mode' did work if the IP address was the same as the IP derived from the default MAC address.
