Closing the switcher

To close the switcher when you have finished performing a procedure in this chapter, do the following:

1.Reinstall any cables you removed. To connect a self-latching cable to a

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

2. Place the top cover (and the front cover if a firmware upgrade was performed) in place and replace all the screws that were removed in Opening the switcher on page B-2.

Swapping the serial ports

The MAV switchers are usually configured for RS-232 use. If you want to use RS-422 and the switcher is configured for RS-232, or if you want to use RS-232 and the switcher is configured for RS-422, do the following:

1.Follow the instructions in Opening the switcher on page B-2 for removing the top cover.

2.Locate the switcher’s front panel board (figure B-2).

4.Remove the RS-232/RS-422 ribbon cable by pressing the two RS-232/RS-422

receptacle tabs outward, and pull up evenly on the cable connector to remove it from the current receptacle.

5. Plug the cable in to the desired receptacle by aligning the holes in the connector with the pins in the RS-232 or RS-422 receptacle, and pressing evenly until the receptacle tabs lock into place.

6. Reinstall the switcher’s cover. See Closing the switcher on page B-3.
