Table 3: Available Special Operations
Special Operation
Number of presses (and binary
representation)
Usage
Force port scanning to
first two ports
(
Scanning runs until
current scanning delay
setting times out. Default
is 30 seconds).
ONE press
This forces the first two ports to RS-232
mode, causing the SCM to scan these ports
and thereby allowing access to the SCM (see
note below).
Force port scanning to all
ports.
(
Scanning runs until the
SCM is entered or until
the unit is powered
down. There is no time
out
).
TWO presses
This forces all ports to RS-232 mode,
therefore all ports are scanned for SCM use.
The Blue Heat/Net Sync will behave in the
same manner as an RS-232 only model (see
note below).
Restore factory default
settings
SEVEN presses
This restores the factory default settings for
ALL
configuration parameters.
NOTE: Why would I need to force port scanning?
Some line interface settings are inappropriate for SCM use.
During boot up, the SCM scans only those ports set for RS-232
mode. If all of the ports are configured for another mode, (1/2
Duplex or Multi-drop) SCM port scanning is bypassed, and the
SCM application cannot be accessed.
Use of either of the “Force
Port Scanning” operations outlined in
Table 1
will force port
scanning to occur so the SCM application can be accessed.
Power On Diagnostics:
LED Error Codes
If an error is detected during the bootup process, an error
condition
and
code
are displayed on
the LEDs on the face of the Blue Heat/Net Sync.
•
The error
condition
is signaled by a rapidly flashing CPU LED (about 10 to 20 per
second).
•
The error
code
is displayed on Port LEDs 1 to 4 as a binary number.
