HP 24SII - Manual (Page 46)


If you are connecting an EIA-232 device to the M24SII-V07 module
using 8-wire Operation, please see
Appendix A.5 for device adapter
pinouts and recommended cabling.
When connecting an EIA-422 device to the M24SII-V07 module using
8-wire Operation, the cable required to connect the two devices must
have TX+ wired to RX+ (and vice versa), TX- wired to RX- (and vice
versa), HSO wired to HSI (and vice versa), and have the signal
grounds connected. Please
Figure 9 .

Figure 9: M24SII-V07 EIA-422 (8-wire) Connection
If you are connecting an EIA-422 device other than another BayTech
product, you must refer to the operator's manual for your equipment to
determine which pins are defined as TX+, TX-, RX+, RX-, HSI, HSO,
and signal ground (common).
If you are connecting another BayTech product (such as Tran-x) using
EIA-422 protocol and 8-wire Operation, please refer to
Appendix
A.7.1 for the recommended cable pinout.
