RS-485 communication requires precise timing control to enable and disable the line driver, and the Moxa Turbo Serial Engine chip that powers the CP-118U-I and CP-138U-I boards come with on-chip ADDC® (automatic data direction control) to make RS-485 as easy to use as RS-232.
RS-485 multidrop for up to 31 devices within 1.2 kmThe CP-118U-I's 8 RS-232/422/485 ports and the CP-138U-I's 8RS-422/485 ports can achieve data rates up to 921.6 Kbps, and in RS-485 mode, one serial port can connect up to 31 daisy-chained RS-485 devices within a range of 1.2 km. In addition, the 2 KV optical isolation protection on the CP-118U-I and CP-138U-I boards helps prevent equipment damage for long distance RS-485 communication.
