thanks Nick for the manual scans!


question for the group
when connecting the 136 to a modem  confirming the pinout on the db25 
1. low level rcv dara  to modem +-6v
2. low level xmt data to modem +-6v
3. DSR 
4. DTR
DTR and DSR get tied together (ready?)
5. RTS  is this a keyline that goes to ground for a transmitter driving a transistor?
15 CTS where would this go?
25. ground

thanks
Jeff

I have scanned the July 1991 edition of the UGC-136BX manual.
To make things easier to print, I have also broken out separate files of the fold-out pages (some are 11x48) and the letter-sized pages (8.5x11).
The complete thing is about 300MB. Links are at

Please let me know if I need to re-scan anything.

Have Fun!
