MultiSmart Installation & Operation Manual
NOTE:
Unless the MultiSmart is configured in a specific way, the Battery Level terminal will only measure the
battery charger voltage – not the actual battery voltage.
7.5.2 DSP Status LEDs
There are four DSP status LEDs labelled COP, Power, Offline and Fault.
Figure 50 – DSP Board Status LEDs
(a) COP (Computer Operating Properly) (Correct State: Slow Flash)
Off: This occurs when the DSP is waiting for the first communications on the bus.
This LED remains off until the Host processor starts running I/O. If the LED stays off, then most likely a
fault is present with the bus and it is preventing the DSP from receiving initial communications from the
Host processor.
Slow Flash: Flashes about once every 2 seconds when the main software is running.
Quick Flash: A faster flash rate (approx 2Hz) indicates that the bootloader is running and waiting for
commands. This will be seen for about 5 seconds after the Host starts running the I/O and also during a
DSP firmware upgrade.
(b) Power (Correct State: On)
This is a power indicator.
(c) Offline (Correct State: Off)
Off: The main software is running. This means that the I/O is running.
On: The bootloader is running. The main software is not running so no I/O is running.
(d) Fault (Red) (Correct State: Off)
Off: Status OK
On: At least one of the I/O boards attached has I/O calibration data which the current firmware cannot
handle and as a result, the I/O is not calibrated. Firstly upgrade the DSP firmware and if the Fault LED
remains on, contact MultiTrode as the I/O is not calibrated.
Flashing: This indicates that at least one of the I/O boards found is incompatible with the firmware. It
means that no I/O at all can operate on the unit. Upgrading the DSP firmware should solve the problem.
