CHAPTER 5: Installation

5.1.4KEYBOARD AND MOUSE

The ACS235A Extender’s keyboard and mouse interfaces are standard PS/2 type interfaces, so you can attach just about any standard PS/2 compatible keyboard and mouse to the Extender. Do not attach serial mice or bus mice to the Extender; they will not work. You can attach a PC/AT style keyboard with a 5-pin DIN connector to the Extender by using a keyboard adapter, available separately as product code FA211.

The ACS236A Extender’s keyboard and mouse interface is a standard Sun type interface, so you can attach just about any standard Sun compatible keyboard and mouse to the Extender. The Extender is transparent to Sun keyboard type and keyboard language.

5.1.5PARALLEL PRINTER (OPTIONAL WITH ACS235A)

The ACS235A Extender’s printer interface is an IBM PC style (Centronics compatible) parallel interface, so you can attach any basic parallel printer (IBM PC or Centronics type) to the Extender.

CAUTION!

This is a printer interface only. It cannot be used to attach Zip® drives and other parallel devices, nor can it be used for parallel file transfer using utilities such as Laplink®.

The Extender also doesn’t support the newer IEEE 1284 or Bitronics® signaling (and the transmission delay would cause timeout problems for these protocols anyway), so don’t try to establish bidirectional, Extended Capabilities Port (ECP), or Enhanced Parallel Port (EPP) communication with an attached parallel printer.

Lastly, you should be aware that the latest version of the standard parallel-printer device driver from Hewlett-Packard®(HP®) will not work with printers attached to a CPU across an Extender link. If you have problems with your printer driver, contact your printer dealer or HP support.

5.1.6SERIAL DEVICE (OPTIONAL WITH ACS236A)

The ACS236A Extender’s serial interface is an EIA/TIA RS-232 serial interface, pinned according to TIA-574 on DB9 connectors just like the serial ports of an IBM PC compatible computer. The serial port on the Local Module is a DCE and the serial port on the Remote Module is a DTE. The Extender supports the TD, RD, RTS, CTS, DSR, and DTR signals. This means that you can attach just about any serial device to this port that you would directly attach to a PC’s serial port, including a printer, plotter, scanner, or touchscreen. Keep in mind, though, that the maximum data rate that the Extender can transmit across the fiber link is 38,400 bps.

ACS236A, ACS235A specifications

The Black Box ACS235A and ACS236A are advanced video and audio extenders designed to facilitate the transmission of high-quality multimedia signals over long distances, utilizing standard Ethernet infrastructure. These devices are essential for professional audio-video applications, such as conference rooms, classrooms, and broadcast studios, where reliable and high-definition signal distribution is crucial.

One of the standout features of the ACS235A and ACS236A is their support for high-definition video formats, including 1080p and 4K resolutions. 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.
