Caterpillar EMCP4
Installation Guide
1. Unpack the monitor, antenna and the data / power cable.
The 25 pin connector plugs onto the front of the
OMNIMETRIX Monitor. This cable includes wires to power
the monitor as well as wires for alarm inputs, relay outputs
and analog inputs. Take a moment to inspect all components
to verify there is no shipping damage.
2. Place the antenna on the roof of the generator and route the
antenna cable through the louvers down into the area of the
generator control. The antenna used for transmitting must be
installed to provide a separation distance of at least 20 cm
from all persons and must not transmit simultaneously with
any other antenna transmitters. BE SURE to provide a drip
loop lower than the monitor to keep water from running down Data / Power Cable
the antenna cable into the monitor connection. If the roof is
aluminum (non-magnetic), simply mount the antenna near the
roof line on the steel side walls.
3. Attach the monitor via its magnetic feet, on top of the engine
controller or other appropriate location. Horizontal surfaces
are best, but the unit may be mounted vertically or even
upside down if necessary.
4. Route the data / power cable to the terminal strip to pick up
generator battery power and RS485 data.
5. The monitor connects to the Caterpillar EMCP 4 through a
simple 4-wire connection. Connect the red wire to generator
Battery B+, the black wire to generator Battery B- (GND), the
white wire to Modbus Data+ and the green wire to Modbus
Data-. For remote start capability, connect the white/yellow
wire and the white/brown wire to the Genset 2-wire Start
CAT EMCP 4 Controller
Terminal.
6. Attach the antenna cable to the front of the monitor, and
tighten thumb tight.
7. Set up Modbus via the front panel control, using the steps
provided on the following page. Be sure to utilize a baud rate
of 9600, 8 bits, no parity, 1 stop bit.
8. Turn on the monitor and confirm that the LEDs light up and
blink. If not, check for power on the terminal strip. If, after 5
minutes, the only LED lit is the Power LED, check the
antenna mount and cable connection.
9. Allow 15 minutes for the monitor to log into the network and
then call OMNIMETRIX at 770-209-0012 to confirm
installation. Access to machine data is through the
OmniView™ web interface at www.omnimetrix.net. Contact
