Black Box ACS235A, ACS236A manual Setting the Jumpers in the Remote Module Optional

CHAPTER 3: Configuring the ACS235A

3.3 Setting the Jumpers in the Remote Module (Optional)

There are six user-settable jumpers inside the Remote Module of the ServSwitch Brand Fiber KVM Extender. They control these options:

•Whether the Remote Module strips the sync signals from the color signals (default) or leaves them in (jumpers JP1, JP2, and JP3).

•Whether the Remote Module uses automatic (default) or manual gain control (jumper bank JP8).

•Whether the Remote Module passes a separate VSYNC signal to the monitor (default) or disconnects it (jumper JP9).

•Whether the Remote Module uses the SYNC polarities transmitted from the local side (default) or forces both HSYNC and VSYNC to negative polarity (jumper JP12).

If you need to set the unit for a non-default option, open the Remote Module— being sure to take all reasonable precautions against static electricity—by unscrewing the upper part of its casing. (The jumper locations on the motherboard are shown in Figure 3-6.) Then set your desired jumpers as described in Sections 3.3.1, 3.3.2, 3.3.3, and/or 3.3.4, and then close the unit back up.
