Configuration Flexibility

PC/104 form factor

To best meet the requirements of your application,
Janus-MM can be ordered with any combination of the
desired I/O:
dual CAN, GSM/GPRS socket modem,
Lassen GPS (SKII or iQ).

Extremely rugged -40°C to +85°C (-40°F to +185°F)
operating temperature

Each port is independently isolated from the system to
eliminate sensitivity to noise and ground shifts in the
network.

Rugged Design
Janus-MM was designed for rugged applications such as
automotive or
on-vehicle.
Extended
temperature
operation of -40°C to +85°C is tested and guaranteed.
Also, 0Ω jumper-bypass resistors can be installed in any
configuration.

Shortened Development Time
Diamond offers CAN drivers for Windows CE and Linux.
These drivers enable you to develop your application
software quickly.
