FAQ
- Will the Toba MEMU-7 digital boat gauges work with my original analogue sensors?
Yes, in most cases any one or two-wire sensor that registers between 0 and 5000 ohms will work well.
- Can I connect the unit to NMEA, CAN or J1939?
No, the Toba MEMU-7 is designed to retrofit boats that have older analogue gauge systems specifically to avoid the need to spend money converting to NMEA or otherwise. It is designed to be a drop-in replacement for those older-style systems.
- What if I have a fuel injected engine, can I still use the Toba MEMU-7?
Yes, in fact, any engine can be monitored by the MEMU-7, it may be that standard sensors need to be fitted but it can be made to work just the same as any other engine. Most MPI engines do have analogue sensors fitted from the factory.
- Can I use a Toba MEMU-7 with an outboard engine?
Yes, in fact, any engine can be monitored by the MEMU-7, it may be that standard sensors need to be fitted but it can be made to work just the same as any other engine. Most MPI engines do have analogue sensors fitted from the factory.
- Can I use the Toba MEMU-7 with big diesels?
Yes, the tacho input is designed to accept the A/C waveform generated by the tacho sensors on many diesel marine engines, in almost all cases the MEMU-7 will accept that signal without issue.
- Is the Toba MEMU-7 waterproof?
Yes, though it is not formally rated, the MEMU-7 is designed specifically to withstand water splash, and spray from the rigors of outdoor use in a marine environment. It is not designed to be submerged.
- Is the Toba MEMU-7 dimmable for night use?
Yes, press and hold the “Toba” logo at the bottom of the screen and the screen is easily dimmable with a slide bar which is at the top of that “Settings” screen.
- What can I monitor with the MEMU-7 additional three generic gauges?
Anything that uses a sensor between 0 and 5000 ohms of resistance. Pressure, temperature and level are the most common however as long as the sensor is a resistance style within 0 and 5000 ohms it can be used.
- Do I need an installer to configure the unit?
Not usually, the most common configuration parameters for sensors are on our website and use of those are generally sufficient. You can get your own values by taking measurements of the sensor in question with a multimeter at varied levels of changed state. We have a comprehensive setup manual that guides you through this process.
- Are there any engines which the unit will absolutely not work on?
No, all engines can be fitted with sensors that will work if the need arises.
- Can I set the gauge alarms to suit my boat?
Yes, each alarmable gauge has an upper and lower settable alarm trigger point aside from Battery voltage and Fuel level which only have low-level alarms. By setting a value in those “High” and “Low” alarm settings, the unit will go into alarm mode for that gauge and only that gauge when the value condition is met. If an alarm is not required, simply leave the alarm config box blank. When in alarm mode, the alarming gauge glows red and the piezo buzzer is turned “on” if it has been wired to the unit.
