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.

This capability ensures that users can experience stunning visuals without degradation, even when transmitting over extensive distances. Both models utilize HDBaseT technology, which enables the transmission of uncompressed HD video, audio, control signals, and power over a single Cat5e/6 cable. This simplifies installation and reduces cabling costs while providing exceptional performance.

The ACS235A is equipped with HDMI input and output, making it ideal for connecting a variety of devices such as projectors, monitors, and media players. Its compact design allows for easy integration into existing setups without occupying excessive space. Additionally, it supports Power over Ethernet (PoE), meaning that it can receive power through the same cable that carries the data, enhancing flexibility in deployment.

Similarly, the ACS236A provides comprehensive support for audio and video formats and includes additional features such as RS-232 and IR control. This capability allows users to manage their equipment remotely, making it easier to control presentations or switch between multiple sources. The built-in LED indicators provide real-time status updates, making it simpler for users to monitor the system’s operation.

Both models are designed with durability in mind, incorporating robust housings and reliable connectors that ensure longevity even in demanding environments. Furthermore, they both support a wide range of operating temperatures, making them suitable for various installations, from corporate settings to educational institutions.

In summary, the Black Box ACS235A and ACS236A are powerful audio-video extenders that combine advanced technology with user-friendly features. Their ability to deliver high-quality signals over significant distances, along with remote control capabilities and efficient designs, makes them an excellent choice for anyone looking to enhance their multimedia installations.
