Hi there…
We have inherited a weird problem! In an Tektronix pdr-300 video server pc.
It uses an ISA ACLII+ 16 422/485 PCB for multiple serial port remote control. These were fitted as std some years ago an many did not have their serial cards in use.
It is Model v80746441 and s/n 50600122 ACLII. the installed driver software appears to be Rocketport and even though we have configured and tried Rocketport dos diagnostic programs we cannot detect the serial card.
We tried different slots and every driver configuration we can set still to no avail. The pdr-200 install manual shows the dip sw and default settings as i/o 200 and irq=15. Sw1 all off and
It appears that it may have been manufactured for Tektronix and i cannot find any info here that matches. Yet the ident labels appear 100% to match Digi’s method of coding.
any clues on being able to get a dos disagnostic program to check these pcb,s (3 all same problem. We dont sus 3 faulty boards just no correct dsriver.)
We have a pdr-200 which uses this exact board and it also has rocketport driver installed and it works 100% But its an on air system and we cant take it offline easily!
any clues/redirection would be appreciated.
