A.2 PS-4C AND PS-4E: EIA-422
INFORMATION
Please see Appendix A.2.1 if using hardware handshaking or
Appendix A.2.2
if using XON/XOFF handshaking. If you are
unsure which type of handshaking you should utilize, use hardware
mode.
A.2.1 EIA-422 HARDWARE
HANDSHAKING
When connecting an EIA-422 device to the PS-4C or PS-4E using
hardware handshaking, the cable required to connect the two
devices must have TX+ wired to RX+, TX- wired to RX-, HSO+
wired to HSI+, and HSO- wired to HSI-. Please see
Figure 13
below.

: EIA-422 Connection using Hardware Handshaking
If you are connecting a device which is not another BayTech
product, you must refer to the operator's manual for your
equipment to determine which pins are defined as TX+, TX-, HSO-,
and HSO+.
NOTE: If your EIA-422 printer or plotter has only one output
hardware handshake line (i.e., no HSO+ and HSO-), connect this
single handshake line to HSI- (Pin 3).
