Dekey Transmitter DKEY
This command deactivates the transmitter after it has been keyed with
the KEY command. If other keying sources are still active, then the trans-
mitter will not dekey, but the manual key request is removed.
Diagnostics Link 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. Net-
work-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 rate selections are allowed:
• 2400
• 4800
• 9600
• 19200 (default setting)
Example: DLINK 4800 sets the RJ-11 DIAG port to operate at 4800 bps.
The same baud rate must be entered into the InSite Equipment List’s
BAUD field.
The default setting is DLINK ON.

Message Gap Time
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 baud rates are slow, the gap
between characters within a poll might be so long that the radio inter-
prets the next character as the start of a new poll. When diagnostics is
performed using passive rather than active messaging (see “Performing
Network-Wide Radio Diagnostics” on Page 84), use this command to
prevent these errors.
