Table 1: Special Operations Available

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 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

or RS-485 Full-Duplex 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.

•

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 on four and eight

port models, and is represented in two port models by the behavior of the Serial 1 and

Serial 2 LEDs (see chart below).
