Identify Cabling with Ease

Integrated label design makes cable grouping and identification simple in enterprise racks or office bundles.

The BLACK BOX® Universal RS-232 to RS-422/485 Converter with Opto-Isolation isolates and converts RS-232 signals into RS-422/RS-485 signals and vice versa. Unlike other converters, external software is not required to control data flow. The RS-232 input is wired for DCE through a DB9 female connector, and RS-422/RS-485 signals are interfaced through a removable terminal block. To supply external power to the terminal block, you need our 120-VAC/12-VDC Wallmount Power Supply (PS1003).

For RS-232, the connection requires RD, TD, and Signal Ground.

In RS-422 mode, the driver is always enabled for full-duplex communications. A twisted pair is required for transmit, and a twisted pair is also required to receive. A ground reference wire is also needed. Switch settings are Switch 1: RS-422; Switch 2: Echo On; Switches 3 and 4: 4 Wire.

In both RS-485 modes, the RS-485 driver is automatically enabled during each space state by the presence of an RS-232 signal. When the RS-232 data is in a mark or idle state, the RS-485 driver is disabled and the RS-485 data lines are held in a mark state by the bias provided by a 4.7-ohm resistor; the value of this resistor may need to be changed, depending on the termination you use.

To connect to several RS-485 devices with minimal wire, select the unit's 2-wire, half-duplex RS-485 mode. When data is requested, the addressed device transmits and then reverts back to receive status. Switch settings for this mode are Switch 1: RS-485; Switch 2: Echo Off; Switches 3 and 4: 2 Wire.

For 4-wire master/slave circuits, select the unit's 4-wire, full-duplex RS-485 mode. In this mode, addressed devices can receive data while transmitting data from a previous request. When used as a master in a single-master system, Switch 1 may be selected because the unit is the only transmitter in the system. When used as an RS-485 slave, the RS-232 device must provide addressability. Biasing in a master/slave system is provided by the end-of-line slave. Switch settings for this mode are Switch 1: RS-485; Switch 2: Echo On; Switches 3 and 4: 4 Wire.

The ServSwitch Wizard™ DVI Dual-Link (USB) 4-Port or 8-Port has breakthrough USB True Emulation technology. This ensures that the full characteristics of the connected USB peripherals-including keyboards and mice-are passed to every system, so specialized features are quickly recognized on the attached devices. What's more, each computer retains this information, even if the device is plugged into another computer. Because of this technology, the switch avoids many of the limitations found in traditional emulations, enabling instantaneous switching and hotkey support.
You can switch up to four or eight PCs via hotkeys, mouse, or RS-232/V.24. The switch provides resolutions up to 2560 x 1600 or 2048 x 2048 at 60 Hz. Plus, it supports duallink DVI-D, single-link DVI-D, and VGA.
Intelligent options port
Flash upgrade the ServSwitch Wizard DVI Dual-Link (USB) via its intelligent options port. You can also switch it via simple RS-232 protocol or even dry contacts. When linked with another ServSwitch Wizard, the options port can be used for synchronous switching of multiple video heads.
USB 2.0 transparency
A clever architecture combines transparent USB 2.0 protocol with emulated keyboard and mouse control. To support this, there are two dedicated keyboard/mouse ports
