Hello,
I need to interface a GNT 3601 puncher to make some tapes, I didn't
succeed yet. I asked for the pinouts from the manufacturer. According to
their document, the communication could be done at 50, 75, 100, 110,
134.5, 150, 200, 300, 600 and 1200 bauds. and the pinouts are:
1 N.C.
2 Transmitted Data
3 Received Data
4 N.C.
5 N.C
6 Data Set Ready
7 GND
8-12 N.C.
13 Current Loop Receive, -
14-17 N.C.
18 Current Loop Receive, +
19 N.C.
20 Data Terminal Ready
21-24 N.C.
25 DC Output, 12v 20mA max
Then I made a null modem cable and connected to the PC, but i can't get
anything punched using windows terminal or the program that i wrote, at
300bauds and neither at 1200 bauds.
I would appreciate your help, thanks.
