DLINK [xxxxx]
DLINK followed by the baud rate sets the baud rate (bps) of the diagnos-
tics link. The following
DLINK baud rates selections are allowed:
• 1200
• 2400
• 4800
• 9600
• 19200 (default setting)
Example:
DLINK 4800 sets the RJ-11 DIAG port to operate at 4800 bps.
The default is
DLINK 19200 and DLINK ON.
NOTE: The same baud rate must be entered into the appropriate
field(s) of any Network Management Software, if used.
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 53), this command may be used
to change this behavior.
DTYPE [NODE/ROOT/GATE/PEER]
The
DTYPE command specifies the radio’s operational characteristics for
network-wide diagnostics. There are four possible types of nodes in a
network-wide diagnostics system.
The common types are:
•
NODE–The most common setting, and the default. This is the
basic system radio device-type. Typically, the radio network is
comprised of nodes and one root. Intrusive diagnostics can orig-
inate from any node. However, non-intrusive diagnostics can
only be conducted from the root node.
•
ROOT–Always one, and only one, per network. The root is the
focal point of network-wide diagnostics information. Intrusive
diagnostics can originate from any radio, including the root.
However, the root is the only radio through which non-intrusive
diagnostics can be conducted.
The default radio device-type is
NODE. Less used are:
• GATE
• PEER
