Operating the VM-2DT
This section describes how to:

Route the IR and RS-232 signals via the HDBT ports
(see
Routing the IR and RS-232 Signals on page 6 ).

Acquire the EDID (see Acquiring an EDID on page 9 ).

Perform Firmware upgrade via K-Upload (see Upgrading the Firmware on page 10 ).
Routing the IR and RS-232 Signals
VM-2DT transports IR and RS-232 signals between the HDBT input and the two HDBT
outputs. Each signal can pass bidirectional commands via the VM-2DT HDBT ports (one input
and two outputs).
The IR/RS-232 signal routing is set via the SETUP DIP-switches .
Setting the DIP-Switches for Routing
Set the DIP-switches as defined by the following table:
Output # IR Routing is
enabled when:
RS-232 Routing is
enabled when:
Figure 3: VM-2DT DIP-Switches
OUT 1 DIP 1
– OFF
DIP 5
– OFF
OUT 2 DIP 2
– OFF
DIP 6
– OFF
DIP-Switches 3, 4, 7 and 8 are preserved
for future use.
For example, in the DIP-switch setup shown in Figure 4 , DIPs 1, and 6 are set to OFF. This
means that IR signals can traverse between IN and OUT 1 ports and RS-232 commands can
traverse between IN and OUT 2 ports. DIP-switches 2 and 5 are set to ON and are therefore
disabled.
