5.2 ELCOM (Vehicle Network Communications Layer)
The ELCOM is a multifunctional layer that supports three dedicated CAN vehicle bus
sources, one generic vehicle bus module interface and a GPS communications port.
The ELCOM layer supports up to 254 vehicle bus channels per input. The layer
comes with many predefined databases such as J1939. The GPS communications
port is designed to work with Somat GPS devices.
Figure 5-2: Diagram of the M8 connectors for CAN, VBM and GPS connections on an
ELCOM layer.
5.2.1 ELCOM Available Inputs
Each vehicle bus and GPS port appears as separate hardware in the TCE hardware
setup window. For more information on vehicle bus inputs and configuration options,
see
“Vehicle Bus Module” on page 99 . For more information on the GPS modules, see
“EGPS-5HZ (Somat GPS Receiver)” on page 96 or “EGPS-200 (Precision GPS
Module)” on page 97 .
5.2.2 ELCOM Configuration Options
Vehicle Bus Module Usage
The vehicle bus module usage parameter displays what type of vehicle bus module, if
any, is defined in the current hardware setup.
5.3 ELDIO (Digital Input/Output Layer)
The ELDIO is an extremely versatile layer that supports digital inputs and outputs,
pulse counters, two vehicle bus module interfaces and optional GPS receiver.
Figure 5-3: Diagram of the M8 connectors on an ELDIO layer.
5.3.1 ELDIO Available Inputs and Outputs
The digital I/O channels are grouped into one bank (A) containing three connectors of
four digital I/O channels (i.e., bits). The eight channels on connectors |1-4| and |5-8|
are individually configurable to be either inputs or outputs. The four channels on
connector |9-12| are dedicated wide-range input channels. Each connector also
provides two pulse counter channels for a total of six pulse counter channels per bank.
One layer also supports up to two independent vehicle bus module interfaces and an
optional GPS receiver, which appear as separate entries in the TCE hardware setup
window. For more information on the GPS modules, see
“EGPS-5HZ (Somat GPS
Receiver)” on page 96 or “EGPS-200 (Precision GPS Module)” on page 97 . For more
information on setting up vehicle bus modules, see “Vehicle Bus Module” on page 99 .
