RS485 Pinout

Figure 3 is an RS485 wiring diagram for RS485 pinout DB9 connectors. Figure 4 is a pin diagram for both 25 pin RS485 pinout half duplex and full duplex pinout connectors. The TxD+ and TxD- lines carry transmit data while the RxD+ and RxD- contain the receive data. The distances these signals are carried is greater due to differential signals.

How should I do the wiring of the 'RS485' line(s) within each enclosure (between each 2 DB9 connectors inside an enclosure serving as RS485 'main line')? Should this be twisted paired cable (CAT5?) or can I get away with normal breadboard wire (since the length is not long, max 45", probably smaller).

A quick tutorial on RS485 and MODBUS

To exchange MODBUS messages, you must therefore use: either a specific program provided by the device vendor, with a compatible interface; or a simple RS485 interface with a programming library which encodes and decodes MODBUS messages; or a smart RS485 interface able to encode and decode by itself the MODBUS messages, such as the Yocto-RS485.
