3.2.3.5 Ext Ref In/Out Connector, BNC
The Ext Ref In/Out 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.

3.2.3.6 Console Port, RJ-11 (w/Optional Packet Processor only)
This asynchronous/serial 6-pin RJ-11 modular port is an EIA-232 DCE interface. You
must use an adapter cable (e.g., CEFD P/N PL/9396-1, available for purchase from
Comtech EF Data Product Support) to connect the User PC to this port, for operation
of the Packet Processor Serial CLI (Command Line Interface).
The CLI provides M&C of modem and Packet Processor functions via a user-
provided terminal emulator (e.g., TeraTerm, PuTTY, or HyperTerminal). See
