Hi, and thanks in advance for any help. I am assembling a MS2 V3. Have checked and double checked the power supply per the instructions, all OK. Completed loopback test of the RS232 comm link, all OK.

Using Download 2.00 to load Monitor_v2.905.abs.s19.

I get the following output (verbosity setting increased to 3):
Reading C:/My Documents/Monitor_v2.905.abs.s19:

I've double checked solder joints, as this was the fix for a prior poster. No luck. Any ideas?

Thanks again.

Problem solved. Switched from an old win98 laptop (direct RS232) to a new laptop (USB converter) and everything worked on 1st try. Sorry to waste bandwidth.
