Serial Ports
The RX1501 supports RJ45 serial ports, which can be run in RS232, RS485 or RS422 mode.
NOTE
On power-up, all serial ports default to RS485 mode. Each port can be individually set to RS232,
RS485 or RS422 mode through ROX II. For more information, refer to the ROX II User Guide for the
RX1501.
All serial ports feature an LED that indicates the current state of the port.
