42 MDS 4790/9790 Series I/O Guide MDS 05-3438A01, Rev. E
• 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.
Diagnostics
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 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 rather than active messaging (see “Performing
Network-Wide Radio Diagnostics” on Page 80), this command may be
used to prevent such errors.
Unit Diagnostic
Service
DTYPE [NODE/ROOT/GATE/PEER]
This command configures a radio’s type for network-wide diagnostics.
For most radio systems, it is sufficient to define a radio as a root or node
radio. The root radio is the radio connected to the host computer for
non-intrusive diagnostics functions. Only one root can be specified per
radio network.
The
GATE and PEER setting are used for complex radio networks and are
included to accommodate network-wide diagnostics in simplex and spe-
cial radio network configurations.
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. The default setting is
NODE.
See Section 7.2, Performing Network-Wide Radio Diagnostics, begin-
ning on Page 80. A complete explanation of remote diagnostics can be
found in MDS’ Network-Wide Diagnostics System Handbook.
TX & RX Emphasis EMP [ON/OFF]
This command is used to enable or disable pre-emphasis and
de-emphasis on the analog input and output signals.
Pre-emphasis is a function used in older analog radios where the modu-
lating signal is increased (at the transmitter) at the higher frequencies to
increase system performance. De-emphasis compensates (at the
receiver) for a signal that has had pre-emphasis applied.
