AUXSerial/RS485 Registry Key NAME AUXSerial/RS485 DEFAULT disabled DESCRIPTION By default the RS485 mode is disabled. RS485 communications are only available with the Model 410 JNIOR. When enabled the RX, TX, RTS and CTS lines are reconfigured. The transmit drivers are disabled and can be controlled by the application program. Originally the Model 410 JNIOR included internal jumpers allowing the unit to be configured for RS-422 or RS-485 wiring including optional termination resistors. In general these requirements are now achieved with external wiring. Some 410 PCBs still have an unpopulated location for jumpers that may be used.
