Frequently Asked Questions

Can I unlock my controller?

If you have forgotten your controller password, it can be found using the password decode function.

You will need the following information about your device:

  • serial number
  • "password decode" number
Both numbers can be obtained through the monitoring software relevant to the device.
  • Serial number is available in Controller info
  • Password decode number is available in Values / Info

You can also show these numbers on your device's display. Typically, this requires a sequence or combination of buttons to be pressed. Details can be found typically in the device Operator guide.

Once you have these numbers, please contact your ComAp distributor and they will help you get your password back.

 

Do you support communication to (IVECO, Cummins, MAN, VOLVO, etc.) ECUs?

Yes, ComAp devices are capable of communication with electronic engine control units (ECUs) from the majority of engine manufacturers.

Typically, you connect the ECU directly to the controller using CAN bus. If the ECU does not support the J1939 communication protocol you need to use a communication interface either on the ECU side (such as SAM CCB2 or SmartConnect modules) or on the ComAp side using the I-CB communication bridge.

The communication is typically bi-directional so we support reading of values from the ECU as well as sending commands to the ECU (Start, Stop, etc) and controlling the engine RPM.

For details including physical connection, configuration steps and troubleshooting help please consult the Electronic Engines Support Guide available on this website.

How do I change the controller firmware? Where can I get the latest firmware?

You can download the latest firmware package on the webpage of the device. You can easily navigate there through the ‘Products’ section or just use the Search function. If you cannot find the firmware on the website or if you require different than the offered version do not hesitate to contact our support team.

The firmware upgrade itself is easy to perform. You need the appropriate configuration software and a connection to the controller (preferably a direct connection). Prior to initiating the update process, we strongly recommend you to save a complete backup of your device.

It usually consists of several steps:
  • Create a controller back up.
  • Update the device firmware. It will contain default Configuration Archive and default Application.
  • Change the Application (SPtM, MiNT, MCB, MGCB, BTB, etc) to the required type (by programming appropriate default archive to the controller).
  • Use the Import Configuration Wizard to restore your previous configuration. In some cases manual interventions might be needed during this step.
  • Optional: Update the connected display firmware or device communication module firmware.
Should you be unsuccessful in programming the new version, the rollback procedure is to install previous firmware version and use your back up to restore the controller to its original state before the firmware upgrade was attempted.

How do I connect to my ComAp controller? What types of connections are supported?

ComAp offers a wide range of options to connect to your controller:

  • RS232 / RS485
  • USB - USB A<->B (usually a printer cable)
  • Internet connection - LAN, GPRS, 3G, 4G

Note that some connection types require you to use a communication module (plug-in eg a RS232 card) or communication bridge (external device eg Internet Bridge NT).

Each ComAp device usually allows for multiple ways of connection. The simplest one supported by the majority of our devices is the RS232 (serial) connection. For this, you need an RS232 cable (null modem) and if your PC is not equipped with an RS232 port you need a USB<->RS232 converter.
USB connections are very common. Almost all ComAp devices support connection using simple USB A<->B cable (printer cable) for easy configuration. Some devices can be powered from the USB port for programming to allow easy configuration right on your desk.
Other connection types: Internet connection (LAN, GPRS, 3G, 4G), Modbus RTU, Modbus TCP, SNMP, AirGate, Modem.
Note that some connection types require you to use a communication module (plug-in eg a RS232 card) or communication bridge (external device eg Internet Bridge NT). Not all types of connection are possible on each device. You can find all the details related to this topic in your device's Comprehensive guide or Communication guide.

What do SPtM, MINT, MGCB stand for?

SPtM = Single Parallel to Mains
MINT = Multiple gen-sets with INTernal sync and load sharing
MGCB = Master Generator Circuit Breaker
