3.8. Serial Ports: RJ45
The RX1510 supports serial port line modules with RJ45 connections. On power-up, all serial
ports default to RS485 mode. Each port can be individually set to RS232, RS485, or RS422 mode
via software.

Pin 2 is reserved for future IRIG-B output. Do not connect Pin 2 at this time; doing
so may cause hardware damage. Pins 7 and 8 are connected internally. No internal
termination is provided. In RS232 mode, these pins enter a high impedance state.
A DTE that asserts RTS will see CTS asserted, but hardware flow control is not
performed on the port.

3.9. DDS Ports: RJ45
The RX1510 supports DDS port line modules with RJ45 connections. The 56 kbps DDS port is
compatible with Bellcore standards. Each DDS module features a single 56/64 kbps DDS line
interface with a standard RJ45 receptacle.
