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.
