Operating the VM-214DT
Acquiring the EDID
Each input on the VM-214DT has a factory default EDID loaded (see Default EDID
on page 30). This lets you connect the power before having to connect one of the acceptors.
The VM-214DT reads the EDID, which is stored in the non-volatile memory.
The following procedure is usually done only once, when the device is being set up.
To acquire the EDID:
1. Press the EDID Select button repeatedly until the required EDID source is selected,
(either Default, Ext, or one of the outputs).
The relevant LED lights green.
2. Press the EDID READ button.
The EDID Read button lights red for a short while and the EDID is copied to the currently
selected input. If the EDID Read button flashes twice after the first flash this indicates
that the EDID was not read and the device reverts to the last stored EDID, as indicated
by the LEDs.
Note: If the EDID READ button is not pressed for five seconds, the procedure is terminated
and the device does not store a new EDID. The last EDID is restored.
The EDID can also be modified using EDID Designer.
RS-232 Control and Pass-Through Using the VM-214DT
The VM-214DT can be controlled via RS-232. As shown in Figure 5, you can connect a PC
(or other serial controller) directly to the VM-214DT to control the VM-214DT.
The VM-214DT also transparently passes bidirectional RS-232 signals over the TP cable from
the TP-580Txr transmitter to the TP-580Rxr receiver. For example, a PC connected to the
RS-232 port on the TP-580Txr can control an RS-232-controllable device (for example, a
projection screen) connected to the TP-580Rxr.
