NOTE
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.

DDS Ports: RJ45
The RX1512 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.
