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.
M24SII-V07 (EIA-422, 8-wire) | Equipment |

1 | HSO | HSI | |
2 | GND | GND | |
3 | TX+ | RX+ | |
4 | TX- | RX- | |
5 | RX- | TX- | |
6 | RX+ | TX+ | |
7 | GND | GND | |
8 | HSI | HSO | |

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.
