DATAKEY [ON/OFF]
This command displays or sets the keying mode. In key-on-data mode, the
radio will automatically key itself whenever input data arrives on the DB25
port. In key-on-RTS mode, the radio will only key in response to an RTS or
PTT signal (or the
KEY
command).
Entering the
DATAKEY
command alone shows whether the keying mode is
key-on-data (
ON
) or key-on-RTS (
OFF
). Entering the
DATAKEY
command
followed by a parameter controls whether or not the radio will automatically
key on receipt of data. The
ON
parameter sets the radio to key-on-data mode.
The
OFF
parameter sets the radio to key-on-RTS mode. The default mode is
key-on-data.
Note that key-on-data mode is only applicable when the input data source is
digital. When the input data source is analog, the
DATAKEY
setting is irrelevant.
DATE [mmm dd yyyy]
This command sets or displays the date. The accuracy of the date and time are
important, because event codes are “stamped” with the date and time.(See also
“TIME [hh:mm:ss]” on page 43.)
Enter the command without any parameters to display the date. Enter the
command in any of the following formats to reset the date:
DATE mmm dd yyyy
DATE mm-dd-yyyy
DATE mm/dd/yyyy
where
mmm
is a three-character abbreviation of the month:
Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec
dd
is a two-digit number from 01 to 31 representing the date, and
yyyy
is the
year. The radio’s calendar is fully compliant with year 2000 standards.
DKEY
This command deactivates the transmitter after it has been keyed with the
KEY
command. (If other keying sources are still active, then the transmitter will not
dekey, but the manual key request is removed.)
DLINK [ON/OFF/xxxx]
This command disables or re-enables network-wide diagnostics at the local
radio, and sets the baud rate at the radio's RJ-11
DIAG
port. Network-wide
diagnostics is enabled by default.
Entering
DLINK ON
enables network-wide diagnostics. Entering
DLINK OFF
disables network-wide diagnostics.
Use the
DLINK
command locally, at the radio, to enable network-wide
diagnostics functionality as well as set the baud rate at the RJ-11
DIAG
port.
DLINK
followed by the baud rate sets the baud rate (bps) of the RJ-11
DIAG
port. The following baud rates selections are allowed:
