Comm Software
Connecting the Control and the Computer
Remove power from both the Series 942 and your computer before connecting
them together. This prevents noise or static interference from entering the data
communication lines. Assemble a cable and the appropriate wiring at your
computer. Refer to the wiring on Page 4 through 6.
As soon as you connect the data communications line(s), you're ready to apply
power to your system.
Series 942 Communication Parameters
To communicate with the Series 942, match the serial port settings of your
computer with the available settings in the 942:
bAUd Rate = 300, 600, 1200, 2400, 4800, 9600 (choose one)
dAtA

7 E = 7 data bits and even parity
(choose one)
8 n = 8 data bits and no parity

The bAUd and dAtA parameters are found under the Setup menu.
