3.4.4 Ext Ref Connector, BNC

The Ext Ref connector is a BNC female connector. The signal here is user-supplied
for phase-locking the internal 10MHz reference oscillator, and can be 1, 2, 5, 10 or
20 MHz. The impedance is matched for 50/75Ω, and requires a level in the range –6
to +10 dBm.
Connector Type
BNC

3.4.5 Async- Serial Console, RJ-11 (with Optional IP Module only)

The Serial Console Connector is a standard 6-pin RJ-11 modular jack. The Async-
Serial Console interfaces the IP Module Command Line Interface (CLI) and is used for
management of CDM-570L and IP Module functions using a terminal emulator
connected (with the supplied adapter cable) to the Console port. This is an EIA-232
DCE interface.
