Flash Programmer Updater Messages
The Firmware Updater program may respond with one of the following messages
to indicate that the upload did not occur.
“Timed out” or “Could not find Unit” messages indicate a communication problem
between PC and 5X00. Reconfirm Communication menu configuration, com port
settings, and RS232 connections. (A power cycle may be required to access the
Communications menu.)
“Unit is Up-To-Date” indicates that the 5X00 has most recent firmware and upload
is not necessary.
Force Downloader
If above steps result in errors and if the upload is still unsuccessful, it is possible
that the 5X00 is not in downloader mode. Force the 5X00 into downloader follow-
ing the steps below.
A status LED on the I/O Board must be visible to determine if the 5X00 is in
downloader mode. The status LED flashes about 10 times in 5 seconds when in
downloader mode. When not in downloader mode, the status LED flashes more
quickly about 15 flashes in 5 seconds. The led at the “status/reset” location of the
I/O Board indicates the current status of 5X00 boards.
Directions to Force 5X00 into Downloader
1. WARNING: Disconnect external power to 5X00. (AVERTISSEMENT :
déconnectez l’alimentation externe de l’unité.)
2. Open front panel - page 41.

you are only touching the reset button on the I/O board and the enter
key, then turn power on. The Downloader (bootstrap loader) screen
should appear on the instrument.

General Alarm
Menus → System → General Alarm
The General Alarm triggers the buzzer, general alarm relay, general alarm icon, and
5X00 emails. Sensor and aux system alarms, slave failure (networks), low battery
alarms and ODO probe failure (ODO probe failure alarms apply to only 5500D-
01, 5500D-02 and 5500D-04 instruments) alarms trigger the General Alarm when
enabled.
If individual system alarms are not enabled, the General Alarm will
not trigger.
The General Alarm (buzzer, relay, emails, icon) remains active until one of the four
softkeys
on the front panel is pressed. Pressing one of
the four softkeys while in the Run Screen stops the buzzer, de-energizes the General
Alarm relay, stops 5X00 emails, and removes the General Alarm icon. Pressing one
of these keys also resets the sensor and aux alarm systems. If the alarm condition
still exists after Alarm Hold period(s), the General Alarm triggers again. Low bat-
tery and slave failure alarms are not reset when softkeys are pressed.
