Diamond Systems Janus-MM - Dual CAN Ports, Carrier for Wireless and GPS Modules on PC/104

Dual CAN 2.0B Interface, Socket for GPS Receiver, Socket for Multitech Modem

Introduction

JANUS-MM combines dual CAN interfaces with sockets for GPS communications to create a complete I/O subsystem for automotive and vehicle tracking applications. The dual CAN ports use the Philips SJA1000T CAN controller and 82C251 transceiver, for full CAN2.0B functionality. Each port is independently isolated from the system to eliminate sensitivity to noise and ground shifts in the network. Jumper options include slew rate control, transceiver power source (on-board or loop power), address, and interrupt settings. Both memory and I/O addressing are supported. For ruggedized applications, 0? jumper-bypass resistors can be installed in any configuration.

JANUS-MM supports the Condor C2626 GPS receiver from Trimble Navigation. A connector is provided to supply backup power for the GPS almanac. A built-in dual UART circuit provides the necessary interface to the modules. The add-on module is available pre-installed or separately based on your desired configuration. 

GPS Add-on Module

Janus-MM supports the addition of a GPS module for location identification and wireless communications. One GPS module can be installed on a single Janus-MM board. The module can be ordered pre-installed on the board. Antenna and transition cables are available to connect between the module and the enclosure wall.
