DKEY
Unkey Transmitter This command deactivates the transmitter after it has been keyed with
the
KEY command.
DIN [ON/OFF]
Digital Input When DIN ON is selected, the “not” PTT line (Pin 16 on the DB-25) is
re-defined as a digital input for network-wide diagnostics.
See “User-Programmable Interface Output Functions” on Page 36
for more information. The default is
DIN OFF.
To change the diagnostic link, enter
DLINK followed by one of the fol-
lowing baud rates: 1200, 2400, 4800, 9600, 19200 (default).
DLINK [ON/OFF/xxxx]
Diagnostic Link This command is used to configure the local diagnostic link protocol
used in network-wide diagnostics.
DLINK ON enables the diagnostic link. DLINK OFF disables 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).
DTYPE [NODE/ROOT]
Unit’s Diagnostics
Type
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
DUMP
Read Current Unit
Profile
This command displays all the programmed settings with this one com-
mand. The HHT display is too small to list all the command settings at
one time. Therefore, this command is most useful if the command is
issued from a computer or full-screen terminal.
EMP [ON/OFF]
Modem TX Audio
Pre-Emphasis
This command displays or sets the TX pre-emphasis and RX
De-Emphasis when the radio is operating with the analog mode and the
radio’s MODEM is turned off (
MODEM NONE). It should match the other
radios in the system. The use of pre and de-emphasis helps to reduce the
detrimental influence of high frequency audio noise.
