AUX Commands
The following AUX commands support the auxiliary serial interface path to and from the
External Time Reference (GPS/CDMA).
AUX TYPE – Allows the user to display and change the type of External Time Reference
connected to the chassis. This change is not persistent until/unless the user issues a SAVE
command.
The following AUX TYPE # are for the internal storage definition (and value):
0 – UNKNOWN
1 – HP/Symmetricom 58503 (GPS)
2 – HP/Symmetricom 59551 (GPS)
3 – Zyfer NanoSync or NanoSync II (GPS)
4 – EndRun Technologies Cf or Cfr (CDMA)
AUX BAUD – Allows the user to display or change the BAUD rate of the chassis’
auxiliary serial interface. This change is not persistent; since generally the BAUD rate is
preset based on the TYPE of External Time Reference connected. This command is
provided as a means of manually configuring the serial port to temporarily allow access
external devices that do not match the standard settings. Supported BAUD rates are
currently limited to 9600, 19200, and 38400.
AUX LEARN – Causes the chassis to execute a test to try to determine what type of
External Time Reference is connected to the chassis. This does not automatically change
the value defined by the AUX TYPE command. This is most useful for determining the
type of time reference connected to a remotely configured chassis using a TELNET
session.
AUX ID – Queries and displays the identification string associated with an External Time
Reference. Commonly these identification strings include such information as the type
and version of the time reference. The AUX TYPE must be correctly set before executing
this command.
AUX CMD – Supports a pass-through path to and from the External Time Reference’s
serial interface. This allows access to any of the External Time Reference’s native
commands. Refer to the vendor specific documentation for a description of the available
commands.
