The XA2/XS2 are mature products introduced in 2005.

They are supported in IQAN 5.04 (soon to be 5.05), but because the old hardware does not support CAN FD or high speed, and SIL2 expansion requirements - it is not in IQAN 6.

The 15 year age of the modules does mean that we must plan for components used in their manufacture to go EOL in the near future.

The MC2 and MD3 are of similar age and have similar technology limitations. A planned phase-out timeline will be announced when it becomes necessary to retire these hardworking modules.

For any new design I would recommend moving to IQAN 6 and the MD4/MC4x/XC4x group of products.

The Pulsar valve can still be used, but you need to specify the PF type coil. It is a 90Hz solenoid that is not the digital poppet design that requires the negative spike. The PF version Pulsar works very well with the MC4x controllers. As for the salt spray note, it is always included because of the aluminum enclosures, if the finish were marred, the salt will start reacting with the aluminum.


Hi Pradeep

The PEAK adapter is supported from IQAN 4.06 and later. In my experience, you only need pins 2 and 7. I have built DB9 connectors to interface with only those 2 wires, I also have used just the CAN wires with Deutsch DTM sockets and slipped them over the pins in the adapter connector.

There are probably others that will work. We chose the 1.5k value because it is a common address idTag from Parker (address 3). The purpose is to limit the current in the RTC wire so it could not be shorted to another wire that is controlled by the ignition and inadvertently power up the module. The resistor should be as close to the battery as possible to protect the entire length of the RTC wire.


The +BAT is tied inside the module, so if one of the wires were to break or be damaged you would pull all the current to handle the outputs through a single 20 A fuse. We prefer the 40 A fuse close to the module and then a Y splice to the +BAT pins.

I see the model I used is of course, no longer available. But many similar routers are out there.

There is a CAN gateway and router, with WiFi and 4 x LIN in development at Electronic Controls Division. The translation would be to J1939, not IQAN protocol. Launch is a ways off yet - does it sound like it may do what you need?
