, connect:
 OUTPUT 1 to display device 1 (for example, an LCD TV)
 OUTPUT 2 to display device 2 (for example, an LCD TV)
 OUTPUT 3 to display device 3 (for example, an LCD TV)
 OUTPUT 4 to display device 4 (for example, a plasma display)
3. If required, connect a PC and/or controller to the RS-232 port (see
Section
5.2).
4. Connect the power adapter to the device and to the mains electricity
(not shown in
Figure 2).
5. If required, acquire the EDID (see Section

To select an active input:
• Press the INPUT SELECTOR button to toggle between inputs 1 and 2
5.3 Connecting a PC/Controller via RS-232
You can connect a PC or serial controller to the VM-24HC using the
RS-232 connection. Note that a null-modem adapter/connection is not
required.
To connect to the VM-24HC via RS-232:
• Connect the RS-232 9-pin D-sub rear panel port on the VM-24HC
unit via a 9-wire straight cable (only pin 2 to pin 2, pin 3 to pin 3, and
pin 5 to pin 5 need to be connected) to the RS-232 9-pin D-sub port on
your PC/controller
5.4 Acquiring the EDID
Initially
3
the VM-24HC operates with the factory default EDID
4
stored in
the non-volatile memory. The source reads the EDID from the device
when the device is plugged in or powered on.
1 As required. Up to four outputs can be connected. Not all outputs need to be connected
2 Only connections to the first and last acceptors are shown in
Figure 2
3 This is usually done only once when the unit is being set up in an installation. Once acquired, the EDID is saved in non-
volatile memory and further acquisition is not necessary
4 The VM-2DH reads the EDID, which is stored in the non-volatile memory
