VIMS A5N2 ECM
Following are the Module Identifier (MID) codes for the VIMSTM A5N2 ECM:MID 161 - VIMS ECMVIMS Persistent RAM
VIMS ECMs store data for the machine in persistent RAM. Persistent RAM is retained by a permanent battery. Table 1 is a list of the contents in RAM that will be altered when a VIMS module is flashed.The following data is stored in persistent RAM:
Date
Time
Payload calibration
All data files that can be downloaded
Active events
Logged events
Configuration parameters
Machine serial number
Equipment numberNote: Active events are stored in memory when the key start switch is turned OFF.

(1) The VIMS onboard software contains the source software (flash file) and the configuration software. Cat® Electronic Technician (Cat ET) must be used to flash this software.
(2) Installation of the new configuration software or the same configuration software clears the configuration type.Information Presentation
VIMS collects and stores data from other systems on the machine. This information is given to the operator via the:
Display
Action lamp
Action alarmData
The information system uses the following four types of data:Sensed - Data is read from the sensors and the switches. The sensors and the switches communicate with the VIMS ECM.Internal - Internal data is generated within the VIMS ECM. The date and time are examples of internal data.Communicated - Data received through the Cat Data Link from other machine systems. For example, the engine speed is received through the data links from the Engine ECM.Calculated - Data mathematically determined by the VIMS ECM. For example, the event duration is calculated and stored in the event list.Data Links
Following are the machine data links:Cat Data Link - A two-wire data link that allows communication between the ECM and other machine control systems.CAN Data Link - A three-wire data link that allows communication between ECMs for a transfer of the parameter data.RS-232 (Service Tool) - Serial three-wire data link allows communication between the VIMS ECM and the service tool (laptop computer).RS-232 (Broadcast) - Serial three-wire data link allows communication between the VIMS ECM and other off-board systems that are not service tools. The onboard data can be passed from the machine when a radio telemetry system is connected to the port.Ethernet (10baseT) - A four-wire data link that allows communication to the VIMS modules for uploading configurations and downloading VIMS data.VIMS RS-232 (Telemetry Broadcast Port) Communication
When the VIMS RS-232 Broadcast port is connected to a telemetry system, VIMS automatically broadcasts "Events and Payload" information. The information is via the VIMS telemetry port normally referred to as "Service Port 2". The following items describe both broadcasting
