2.3.2 RS422 Connectors & Pinout
There are limitations on the RS422 Master/Slave cabling:
Shielded cables must be used to achieve the prescribed EMC
The overall length of the RS422 Master/Slave over all units in the chain must not exceed 1000 m (3200 ft).
The distance from one unit to the next must not exceed 300 m (1000 ft).
This table is valid for Cat 5 cabling with gauge diameters of AWG24 (0.25 mm²).

WARNING
The RS422 Master/Slave uses RS422 levels on its RX and TX Pins, although Ethernet jack/plugs mechanically
fit, the device is not Ethernet compatible.
If devices are powered by the RJ45 cabling of the RS422 Master/Slave, wire gauge must be at least AWG24
(0.25 mm²).
