Engenius MULTICOM RF DATASHEET

MultiCom RF

Multi-Purpose Vehicle
Interface Adapter for
Wireless Applications

EnGenius’ MultiCom RF is a flexible solution that
provides simultaneous access to multiple vehicle
networks as well as digital and analog
input/output. (Custom protocols can also be
supported.) MultiCom RF interfaces to a host via
Radio Frequency.

MultiCom RF’s unique design consists of a set of
Physical Interface Modules (PIMs) that plug into
its base platform. Each PIM (standard or custom
designed) contains the specific int erface circuits
that allow MultiCom RF to connect to external
devices. The PIMs and the base platform can all
function simultaneously. This multi-purpose
vehicle interface adapter provides a powerful, yet
flexible, solution to meet a wide range of needs.
MultiCom RF is packaged in a 8" x 7" x 2.75"
sealed metal enclosure.

Typically, the MultiCom RF is configured as a
stand-alone module executing a custom
application and using one PIM slot for RF
communications. This configuration allows
access to all of the adapter’s resources and,
when required, to the outside world via RF.

Interface Capabilities

MultiCom RF is capable of supporting ISO 9141,
ISO 9141-2, ISO 14230, ISO 11519-4, ISO 15765,
SAE J1850 PWM, SAE J1850 VPW, CAN, SAE
J2284, Ford’s DCL, RS485/RS422, Ford’s UBP,
SAE J1939, SAE J1708, and others (including
custom protocols).
