• Connect the monitor desired to read the EDID information from
to the SW OUTPUT Connector.
• Connect the PC to the RS232 port
• On the PC, run and configure HyperTerminal to read the COM
port with 4800, 8, none, 1 and No handshake. See the paragraph
titled “To configure HyperTerminal” above for more
information if necessary.
• Power the VS-2A-PRG and the Monitor
• HyperTerminal will display the power-on menu.
• Hit the "R" key once and HyperTerminal will show a series of
HEX digits appear that were read from the connected monitor.
A display 'Similar' to below will be shown (the actual data
displayed will depend on the device connected to the SW
OUTPUT Connector):
00FFFFFFFFFFFF00106C901991030000280F01037A241D782

• Disconnect the Monitor from the SW OUTPUT Connector
• When programming a Mini-Cat sender, connect the Mini-Cat to
the SW OUTPUT Connector and power up the Mini-Cat. If
programming an EDID emulator, plug in the emulator into the
SW OUTPUT connector.
• Hit the "W" key once and HyperTerminal will show a series of
".' characters for each HEX byte written to the Mini-Cat such as:
........................................................................................................
........................
NOTE
The operator should be very certain about what is connected to
the SW OUTPUT connector before hitting the ‘W’ key. If a
video monitor is connected to the SW OUTPUT connector and
‘W’ is pressed, the monitors EDID information could be
accidentally overwritten and unless previously saved,
unrecoverable.
