The SDI to DVI Adapter has an RS422 port that can be used to view the current settings
of the unit. To connect the RS422 port to a PC you need a special RS422-RS232 cable
that can be purchased from Gefen by contacting support@gefen.com You can also
make the cable using the wiring diagram shown at the end of this document.
• Connect COM1 of the PC to the SDI to DVI Adapter using the RS422-RS232 cable
• Run HyperTerminal on your PC and make a direct connection on COM1
• Connection Properties should be set to: 38400 Bauds, 8 Data Bits, Odd Parity, 1 Stop
Bit, and None Flow Control.
When you power up the SDI to DVI Adapter, plug or unplug the SDI input or DVI output.
Messages will be displayed in the HyperTerminal window indicating the input and output
formats as well as the native monitor resolution reported by the EDID message.
Since the SDI to DVI Adapter does not have OSD capabilities, this is the only way to
verify the SDI to DVI Adapter's current settings.
Auto Mode shows the input format in the message, other modes don’t (see example
below)
• A “A” or “B” after the input format designates the input channel.
• A “p” after the output format designates a progressive output mode.
• A “PT” after the output format designates a pass through mode.
