Description
Engine Parameters
Specifications
The Murphy Display and Diagnostic Module or
MDDM is the keystone in a line of components
manufactured by FWMurphy as part of its J1939
MurphyLinkTM System. The J1939 MurphyLinkTM
System has been developed to meet the needs for
instrumentation and control on electronically
controlled engines communicating using the
SAE J1939 Controller Area Network (CAN).
The MDDM-MOD is an additional model of the
MDDM series. The MDDM-MOD can translate
SAE J1939 to MODBUS † RTU registers for
remote monitoring via satellite, land lines and cell
phones or other controller and computer systems.
This powerful unit is an easy to use multifunction
tool that enables the operator to view many different engine parameters and engine service codes.
The MDDM-MOD includes a two-line by eight
character backlit LCD display. The top line displays
data labels (e.g. OilPress). The bottom line displays
appropriate units (e.g. 80 psi for oil pressure).
The UP and DOWN push buttons located on the
front of the MDDM-MOD, are used for scrolling
through the parameters and viewing the menu list.
Two LEDs (amber & red) are used to annunciate
active fault messages received by the MDDM-MOD.
MODBUS † devices can be connected to the
MDDM-MOD by an RS485 twisted pair cable up
to 1,000 meters. The MDDM-MOD can be powered by 12 or 24* volt systems, is back lit using
LEDs, and is environmentally sealed.
The following are typical engine parameters displayed and made available via
MODBUS † by the MDDM-MOD in
