Subject: OMS VME58 card and user definable I/O

Hello everyone,

I'm having small problems with the additional I/O signals on the OMS VME58 board. I'm using a debug routine that can send commands to the board and have some means of receiving them. I have also set the jumpers on the board to select bits 0-7 as outputs and 8-11 as inputs. Considering that RB command returns input/output configuration and BX returns the current value of the signal, I here state the whole testing results:

##########################
> "bx;"
< "\n\r0fff\n\r"
> "rb;"
< "\n\r30ff\n\r"
> "bh0;"
> "bx;"
< "\n\r0fff\n\r"
> "bx;"
< "\n\r0fff\n\r"
> "bl0;"
> "bx;"
< "\n\r0fff\n\r"
OMS58 Command ("q" to quit) >
##########################

As you can see, I get the correct response to the rb command. However, all bits are high all the time. I cannot change this with bl# and bh# commands. Has anyone got any suggestions? I would very much appreciate it..

Best regards,

Rok
