AV2SM A/V Switcher
Installation
You can install the AV2SM on any flat surface that has unobstructed access to both the front and
rear panel connectors.
Automatic and Manual Switching Mode Settings
You can select the switching mode by setting two internal jumpers on the circuit card inside the
enclosure. You will need a Phillips screwdriver to open the enclosure. To set the switching mode:
1. Discharge the static electricity from your body and screwdriver.
2. Unplug all connectors from the front and rear panel of the AV2SM.
3. Turn the enclosure upside down and remove the two Phillips-head screws.
4. Pull the enclosure apart and turn the bottom half, containing the circuit card, right-side up.
5. Choose the desired switching mode:
! For automatic mode (FIG. 2), place the 2-pin jumper on the E1 connector pin’s one and
two. Repeat for the E2 connector.
! For manual mode (FIG. 3), place the 2-pin jumper on the E1 connector pin’s 2 and 3.
Repeat for the E2 connector.
