CP346 Configuration 4. Configuration 4.1 Hardware Configuration 4.1.1 Serial Mode Configuration The CP346 offers the possibility to configure the operation mode of each channel either with a per default mounted eight Port DIP switch or with solder jumpers (maybe as replacement in case of special conformal coating requirements).
PAGE 52
Configuration 4.1.2 CP346 RS422/485 Termination Jumpers The CP346 offers onboard two 120 ohm termination resistors per channel, which can be used to terminate the differential line pairs in case the serial channel is a beginning or end node of a RS422/485 network. Table 4-3: Termination Jumper Settings for CP346 and CP346-OPT Ch.0 Ch.1 Ch.2 Ch.
PAGE 53
CP346 Configuration Depending on whether the RS485 mode is selected with or without local echo (refer to chapter 4.1.1 for the corresponding setting), the receiver RE signal is always “On” (with local echo) or the RE signal is inverted to the activation/deactivation of the driver DE signal (without local echo). Note... The hardware implementation on the CP346 works with low active DTR/RTS handshaking.
