3.5 RS485 Communication

An iHP system can support RS485 communication with below settings:

 Bits per seconds = 115200

 Data bits = 8

 Parity = None

 Stop bits = One

 Flow control = None

RS485/CAN Bus Terminator or 120Ω terminating resistors are required at both end terminals, PC and iHP rack.

For multiple RS485 communication, the terminating resistor should be placed on the iHP rack farthest from the

PC/Laptop.

Figure 3-7 Terminating resistors required for RS485 interface

The recommended equipment for communicating with the iHP system via RS485 are as follows:

 USB to 2-Wire RS485 Adapter – COMMFRONT USB-485-1 or equivalent

 6-pin RJ11 Connector with Cable
