Internal Programming and Adjustments

WARNING

Hazardous voltages exist inside this equipment. Disconnect the AC line cord before opening the equipment or attempting any internal programming or adjusting.

General

Prior to installing the MCE325, it may be necessary to change some of the internal programming to suit your particular application. Table 2.1 and Table 2.2 list the functions for the DIP switches and jumpers which are used for internal programming. Also shown are the default settings that were pre-programmed at the factory.

If your application requires settings that are different from the defaults, you will have to remove the top cover of the unit (see Figure 2.1) and make the required changes. If you do change the internal programming, it may be useful to note the changes for future reference.

The locations of the DIP switches and jumpers are illustrated in Figure 2.2. DIP switch programming is accomplished by setting switches to the “off” or “on” positions. Jumper programming is accomplished using shorting jumpers. By inserting the jumpers to short the appropriate pins, a function is either assigned or not assigned. Pin 1 of each jumper is indicated by a square symbol in Figure 2.2 for reference when making changes. Also shown in Figure 2.2 are trimmers for adjusting the sidetone and speaker dimming levels. Usage of the DIP switches, jumpers, and level trimmers is described in the following paragraphs.
