[DSP-10] Problems Loading UHF3x35A.HEX

[Richard Miller]

Hi Bob:
Thanks for sending this over. What chip/IC is marked ANALOG? if I understand these drawings correctly the MAX232N is connected to whatever this device is. I will check with HyperTerminal to see, but I am dreading what "ANALOG" is :)

When I attempt to load the Hex UHF3XXX.hex, using FL1B.BAT, I am getting a COMM error on all ports. This is what originally led me to believe my monitor maybe suspect. I have checked my computers com port and it appears to be functioning fine. The MAX232N also appears to be operating normally. As I look through the schematics, I see there is a TXD and RXD line, but I cannot see with these schematics where it goes. I would like to take a look at the device the MAX232N connects too, so if someone can help me there that would be appreciated.

Hi Rich,

This shows the wiring, TXD and RXD are on the GIF file. Hope this is what you are looking for.

The DSP-10 will always output data if UHF3 is running, so you can watch the com port with a terminal program at 9600 8 N 1. If there is no data forthcoming then there is a problem. A little late to mention this I suppose. Just pointing out that the DOS program UHFAxx.EXE is not required.
