• 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

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
