Murphy Display and Diagnostic Module (MDDM) J1939 System Monitor:   (.pdf file)
Displays over 30 standard SAE J1939 parameters broadcast by major engine and transmission manufacturers’ electronic control modules (ECM). Also displays active and ECM stored fault codes to assist in diagnosing equipment malfunctions. Following are some of the J1939 parameters available on the MDDM back lit LCD display: engine hours, oil pressure, coolant temperature, system voltage, engine RPM, % load at current speed, fuel temperature, oil temperature, fuel pressure, engine oil level, coolant level, fuel rate, exhaust gas temperature, and fault codes.

MurphyLink™ Analog Gages: (.pdf file)
Displays critical data transmitted by the MDDM.  The gages have LCD back lighting and illuminated pointers so you don’t have to worry about incandescent bulbs burning out.  All are displayed in a 100% environmentally sealed case and come with a screw on mounting clamp and have a push-on plug connection.
