A solid red LED (not blinking) indicates a fatal error condition. If the event of
a fatal error, the system will power cycle to attempt to self-correct the
condition. If the condition persists, please contact Raymarine Customer
Service.
9.4 Updating Software on the Display Unit
Before it can show sonar data received from the DSM250, the display unit
must be running a software version that recognizes the sounder module on the
hsb
2
network. The DSM250 contains a program routine that automatically
polls the software version running on the display unit and if necessary, updates
it (via
hsb 2
) to be compatible with the DSM250. This Auto Update feature
should be run before using the DSM250 for the first time with a display that is
not an HD Series Fishfinder. The DSM250 will not work with older HSB
(non-PLUS) displays.
Note: Older HSB (non-PLUS) display units must receive PLUS software and
hardware upgrades before they can function with the DSM250.
➤
To automatically check and update the display unit software version:
1. Ensure both the DSM250 and display unit are powered off.
2. Ensure the HSB cable is properly connected between the units.
3. Disconnect the transducer cable from the DSM250. (This is essential.)
4. Power on the DSM250.
5. Within 30 seconds of powering on the DSM250, power on the display unit.
If running an older version, the display software is updated and the unit
beeps. When the software update is complete (or if no update is required),
the normal startup screen appears on the display.
6. Power off the DSM250 and reconnect the transducer.
7. Power on the DSM250.
