When the radio is in CTS Key mode, the timer specifies how long to
wait after asserting the CTS before sending data from the
DATA INTER-
FACE
port. A timer value of zero means that data will be sent from the
data port without imposing a keying delay. Other delays may be present,
depending on how other operating parameters are configured.
Should you experience problems with repeater operation after changing
the
CTS
,
PTT
or
SCD
values, contact GE MDS.
Transmitter Keyed
on Incoming Data
DATAKEY [ON/OFF
]
This command displays or sets the keying mode. In key-on-data mode,
the radio automatically keys itself whenever input data arrives on the
DB25 port. In key-on-RTS mode, the radio only keys 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
com-
mand followed by a parameter controls whether or not the radio will
automatically key on receipt of data. The default mode is key-on-data
(
ON
).
NOTE:
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.
Event Log Date
Format
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 (refer to
“TIME [hh:mm:ss]” on Page 57
).
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 day, and
yyy
y is
the year.
