Some RS-232-C devices may require a high signal for a clear to send (CB)
signal at pin 5, a data set ready (CC) signal at pin 6, or a data carrier detect
(CF) signal at pin 8 for proper operation. Depending on your connections,
note the following:
If you are using the 1775-CDC cable to connect directly between the
1775-S4B scanner and the RS-232-C device or its cable, the 1775-S4B
scanner provides these signals.
If you are constructing a cable for the RS-232-C device, you can jumper
pin 20 to pin 5, 6, or 8 as required by the RS-232-C device.
