Swapping BME #0 RS-232 / RS-422 Ports

Swapping BME #0 RS-232/RS-422 ports (not required on BME #1 - BME #5) involves moving a ribbon cable from one Main Control card connector to another.

Ribbon Cable Connectors

The ribbon cables used in the Matrix 6400 Audio Switcher use a self-latching style receptacle. Figure 5-4.A shows how it operates.

1.Press each of the two tabs outward, this unlocks

the receptacle and ejects the ribbon cable connector part way. Pull evenly on the ribbon cable connector to remove it.

2.When reconnecting the cable, first align the pins

in the receptacle with the holes in the connector and press evenly into the receptacle until the receptacle tabs lock the connector in place.

Swapping Serial Ports (RS-232/RS-422)

Before working inside, unplug the power cord.

The Matrix 6400 Audio Switcher is normally connected for RS-232 use. If your application requires RS-422, follow this procedure (and Figure 5-4.B) to change the configuration. The procedure for removing and installing the ribbon cables is described above in “Ribbon Cable Connectors” above.

1.Power OFF BME #0, unplug the power cord.

2.Remove the Access Panel on BME #0 (Page 5-3), locate the Main Control card (see Figure 5-3.A).

3.Locate ribbon cable receptacles J4 and J5 (Figure 5-4.B). One is empty and the other has a ribbon cable which goes to the rear panel. The ribbon cable plugs into J4 for RS-232 and J5 for RS-422. If the connection is wrong for your application, disconnect the cable and move it to the other receptacle.

4.Reinstall the Access Panel.

5.Plug in the AC power cord, power ON the BME.
