The EMCP 4 supports the renaming of custom events for the event log. This feature is called modifiable text strings. This is useful when an existing SPN and text string do not exist for the required event. These events can be configured and triggered similar to other events. However, these events are unique in that their displayed text strings can be customized via Cat ET using any character in the supported character set of the EMCP 4 software flash file. Furthermore, Cat ET can upload a modifiable text strings configuration file (containing previously saved custom event text strings) from the computer, or download a configuration from the EMCP 4 to the computer.
In order to display a custom text string for an event, the following steps must be taken:
- One of the digital inputs must be configured as a custom event with a failure mode identifier of status (or condition exists).
- A custom string must be entered, using the modifiable text strings tool in Cat ET.
- The language must be set to the customer language, not to Technician English.
An example of entering a modifiable text string for custom event #1 is given in Illustration 1.

The EMCP 4 supports one modifiable text string per custom event on each programmable digital input.
The primary language for the EMCP 4 control will always be Technician English. The user will always be able to revert to Technician English from the selected language that is supported by the flash file. However, when the EMCP 4 display is viewed in Technician English, the user will not be able to view the custom text strings and will only be able to view the default strings (Custom Event #X) for a given input.
The EMCP 4 has the capability of supporting one flash file containing one secondary language at any particular time. If the user is interested in having a new secondary language, a new flash file to configure the new language must be installed. Therefore, the user is not able to install multiple flash files supporting different languages simultaneously.
The EMCP 4 supports Unicode characters from the English character set, as well as the character set from the local language supported by the file. It is the responsibility of the user to install the preferred flash file with the correct language support that will allow the modification of text strings.
The user is also responsible for choosing the appropriate operating system or Unicode text entry system for the chosen language. Cat ET accepts input from the PC keyboard settings. If, for example, the PC keyboard setting is for U.S. English, it may be difficult to enter Russian characters.
Different language software support different sets of characters. Therefore, modifiable text string configuration files created in one language will not become translated if new language software is flashed into the EMCP 4. The original text string will still show as originally entered.
Programming Modifiable Text Strings using Cat ET
To configure a modifiable text string using Cat ET, go through the following menu options:
- Connect Cat ET to the EMCP 4.
Note: Cat ET must be connected to CAN 1.

The modifiable text string is considered a pair of text strings, and the user has the option of customizing the pair of text strings. The second line has less available space, because the event log index is also displayed on that line.

Refer to Illustration 10.
- Select the desired string data and click "Open". This opens the "Modifiable Strings" screen again.
- Edit as desired, then save to ECM, or save to a file.
Note: The modifiable text string parameter value's field is initially blank until it is replaced with a custom text string parameter value. The custom text string parameter value entered will replace the default strings.
The custom text strings programmed by the user are displayed in the preferred language of the user. If the service tool does not support the preferred language of the user, US English will be used.
Note: The user must save any offline changes before attempting to connect Cat ET to the EMCP 4, or the changes will not be saved.
