Cable Requirements, Pin-outs.
Cable Requirements, Pin-outs.
A. For IBM PC's or Compatibles or a Sun workstation with an RS232 port:
1. The plotter uses a straight-through, 25-pin female to 25-pin male
serial cable (CalComp part number 11772-0102, 10 ft. serial
cable; CalComp part number 11772-0250, 25 foot serial cable).
This is not a proprietary cable. It is commercially available,
sometimes called a MODEM cable or EXTENSION cable. Note: A NULL-
MODEM cable is the incorrect cable.
2. The total cable length must not exceed 50 feet.
3. If the computer has a 9-pin connector for the COM port (i.e. COM1
or COM2), a commercially available 9 to 25 pin adapter is
acceptable to perform the conversion.
4. Connect the cable to the port on the back of the plotter labeled:
P0903 - To DTE Host. Regardless of the handshake setting being
used on the plotter, set dip switches 2, 4, and 5 on the back of
the plotter to ON = 1. Turn all other dip switches OFF = 0.
5. Connect the other end to the computer. On a PC compatible
computer the cable connects to the male (e.g., port with the pins
sticking out) serial COM port.
6. A cable that works with another manufacturer's plotter may not
work with this plotter. Other manufacturer's may be using
proprietary cables or null modem cables.
7. The pin-out is as follows:
a. 25 pin female to 25 pin male cable
Ground Pin 1 to Pin 1
TD Pin 2 to Pin 2
RD Pin 3 to Pin 3
RTS Pin 4 to Pin 4
CTS Pin 5 to Pin 5
DSR Pin 6 to Pin 6
SG Pin 7 to Pin 7
CD Pin 8 to Pin 8
DTR Pin 20 to Pin 20
b. 9 pin female to 25 pin male
TxD Pin 3 to Pin 2
RxD Pin 2 to Pin 3
RTS Pin 7 to Pin 4
CTS Pin 8 to Pin 5
DSR Pin 6 to Pin 6
SGND Pin 5 to Pin 7
DCD Pin 1 to Pin 8
DTR Pin 4 to Pin 20
B. If using a Macintosh computer:
1. The plotter uses an 8-pin mini-din Macintosh to 25-pin serial
cable (CalComp part number 16623-0029, 12 ft. cable).
2. Connect the cable from the Printer or Modem port (8 pin mini-din)
on the back of the Macintosh to the port on the plotter labeled:
To DTE Host. Regardless of the handshake setting being used on
the plotter, set dip switches 2, 4, and 5 on the back of the
plotter to ON = 1. Turn all other dip switches OFF = 0.
3. The pin-out is as follows:
Pinouts on Macintosh end of cable:
6 7 8
3 4 5
1 2
a. 8 pin mini-din to 25 pin male
HSKo Pin 1 to Pin 20
HSKi Pin 2 to Pin 5, 8
TxD- Pin 3 to Pin 2
GND Pin 4 to Pin 7
RxD- Pin 5 to Pin 3
RxD+ Pin 8 to Pin 7
