AU J1939 SIMULATOR REMOTE TERMINAL
All Au J1939 Simulator editions can be easily integrated into a SAE-J1939 network (with a 4-wire cable). And all PLUS editions can be connected to a PC (with a RS232extension cable), as shown in figure 4.

Au J1939 Simulator Remote Terminal is available for all Au J1939 Simulator PLUS editions. It is designed for displaying detail information on all simulated SAE-J1939 signal. The interface includes a control panel and a display panel. The control panel is located in the up-left corner. all the other area display info like engine/ABS/Transmission info, warning lamp, etc. as shown in figure 5 - 1, 5 - 2, 5 - 3.
Figure 5 -1 shows the J1939 Simulator Remote Terminal GUI (Graphic User Interface) for vehicle platinum plus edition. All features are active.

- Display Panel – Engine Basic Parameters
Display the following 16 engine basic parameters: Engine Speed(RPM), Engine hour (Hr), Vehicle speed (MPH), Engine oil pressure (PSI), Engine coolant temperature (F), Battery voltage (V), Fuel level (%), Engine boost pressure (PSI), instant fuel economy (MPG), instant fuel rate (GPH), accelerator position (%), inlet air temperature (F), engine load percentage (%), engine trip (mile), total vehicle distance (mile), and engine clock (HH:MM) (figure 6).
Note: Engine Clock is not controlled by the control step value, it runs by itself like a real clock, and can be setup by PGN 54528.

- Display Panel – Engine DM1
Engine DM1 message could be one packet (without warning or with 1 warning) or multi-packet.
If engine DM1is a single packet, SPN, FMI, OC, CM will display (figure 7-1). If engine DM1 is a multi-packet, "see @ Multi-Packets" will display, “Multi-packets” button will be active (figure 7 – 2), click on it, the whole list of engine DM1 will display. If Engine DM1 or DM2 warning is off, a SAE defined non-warning message will be shown as (0,0,0,0).

- Display Panel – Engine DM2
Engine DM2 message could be one packet or multi-packet. If engine DM2 is a single packet, SPN, FMI, OC, CM will display (figure 8-1). If engine DM2 is a multi-packet, "see @ Multi-Packets" will display, “Multi-packets” button will be active (figure 8–2), click on it, the whole list of engine DM2 will display.

- Display Panel – Engine Configuration
Engine Configuration PGN includes 34 bytes of messages which require transport protocol for multi-packet communication. “Engine Configuration” button will be active on the GUI (Figure 9 -1) for vehicle platinum edition(s).

- Display Panel – ABS DM1
ABS DM1 is a single-packet PGN. If ABS warning is off, a SAE defined non-warning message will be shown as (0,0,0,0); If ABS warning is on, a Brake Switch signal low warning will be shown (597,1,7,0) (figure 10).
Figure 10- Display panel – ABS DM1
- Display Panel – Transmission DM1
Transmission DM1 is a single-packet PGN. If transmission warning is off, a SAE defined non-warning message will be shown as (0, 0, 0, 0); if the warning is on, a transmission oil warning will be shown as (177, 0, 126, 0) (figure 11).
