Configuration

Serial Data Link

The SV565UTPUSA/SV565USAGB is able to link two RS232 ports together to allow touchscreens, monitor control ports and other devices to be used remotely. The port’s baud rate is detected automatically and supports 300 to 19200 bps, with 9600 being the preferred rate. If using a baud rate other then 9600 it may take several bytes of data being sent to properly calibrate it. By default the first Receiver Unit has control of the serial port, but any Receiver Unit can be accessed by using the configuration menu on the Transmitter Unit.

Automatic Calibration Button and Light

SV565UTPUSA/SV565USAGB is able to automatically calibrate to different cable lengths in order to preserve image quality. This allows it to work out of the box without any adjustments. Once a good calibration setting is attained, it can be set into fixed calibration mode. This ensures it uses the same settings if it is reset or powered off.

The calibration button on the back of the Receiver Unit can be pressed with the tip of a pen. The image will display a brief test pattern and the indicator light will flash. If it is held for more then half a second, it will switch to fixed calibration mode. In fixed mode the indicator LED below the button will light up and auto calibration will not occur in this state. Press and hold the button again to return to auto calibration mode.

Manual Calibration and Settings Menu

A text-based menu is available on the serial port of both the Transmitter and Receiver units. This can be used to make fine adjustments to the image quality. The menu can be accessed by connecting the serial port to a PC or laptop using a straight-through cable for Transmitter Unit or a null modem cable for Receiver Unit. For computers that don’t have a serial port built in, the StarTech.com ICUSB232 can be used. You can use any terminal communication software to connect to the serial port, such as minicom for UNIX, and HyperTerminal or TeraTerm for Windows.

If the serial data link is being used, the Transmitter Unit will already be set up for serial communication. To connect to a Receiver Unit the serial device must be unplugged first and replaced with the RS232 null modem cable. Use the same baud rate that the serial device and PC had used to communicate.

If you are not using the serial link just attach the RS232 cable and use 9600 bps. Also configure the terminal software to use 8N1, or 8 bits with no parity and 1 stop bit.

An escape code is used to enter the serial menu from data transfer mode. The code is a one second delay, followed by 3x @ symbols, then another one second delay. A confirmation message will appear if it works. If it does not appear, try again a few
