The default selection is
DCE
. In this mode, CTS will go high following
RTS, subject to the CTS programmable delay time. If the
DATAKEY
com-
mand is set to
ON
, keying can be stimulated by the input of characters at
the data port. Hardware flow control is implemented by signaling the
CTS line if data arrives faster than it can be buffered and transmitted.
If
CTS KEY
is selected, the radio is assumed to be controlling another
radio. The RTS line is ignored and the CTS line is used as a keyline con-
trol for the other radio. CTS is asserted immediately following the
receipt of RF data, but data will not be sent out the
DATA INTERFACE
port
until after the CTS programmable delay time has expired. (This gives
the other radio time to key.)
DKEY
This command deactivates the transmitter after it has been keyed with
the
KEY
command.
DLINK [ON/OFF/xxxx]
This command is used to configure the local diagnostic link protocol
used in network-wide diagnostics.
Entering
DLINK ON
enables the diagnostic link. Entering
DLINK OFF
dis-
ables the diagnostic link.
To change the diagnostic link, enter
DLINK
followed by one of the fol-
lowing baud rates: 1200, 2400, 4800, 9600, 19200 (default).
DMGAP [xx]
The
DMGAP
command sets the amount of time in milliseconds to wait
after the receipt of a character before interpreting the next received char-
acter as the start of a new message. When data port baud rates are slow,
the gap between characters within a poll may be so long that the radio
interprets the next character as the start of a new poll. When diagnostics
is being performed using passive messaging (see
Performing Net-
work-Wide Remote Diagnostics
on page 34), this command may be used
to change this behavior.
DTYPE [NODE/ROOT]
This command establishes the local radio as a root radio or node radio
for network-wide diagnostics. Entering
DTYPE NODE
configures the
radio as a node radio. Entering
DTYPE ROOT
configures the radio as a root
radio. Entering the
DTYPE
command alone displays the current setting.
See “Performing Network-Wide Remote Diagnostics” on page 34. Two
associated commands are
GATE
and
PEER
. See MDS’ Network-Wide
Diagnostics System Handbook (MDS P/N 05-3467A01) for details.
