Acquiring The Edid - Kramer VM-114H2C User Manual

2. Connect the TP source (for example, a PT-571 HDMI Line Transmitter
another VM-114H2C or a VM-1114H4C) to the IN 2 (CAT5) connector.
3. Connect the HDMI OUT connectors to up to two HDMI acceptors (for
example, LCD TV or plasma displays)
4. Connect the TP RJ-45 output connectors to up to two TP acceptors (for
example, the PT-572+ HDMI Line Receiver
VM-114H4C).
5. Optional—Plug the remote IR sensor into the front panel remote IR 3.5mm
mini jack.
6. Optional—Connect a PC via RS-232 to the RS-232 port on the VM-114H2C
(see Section
7. Connect the power adapter to the power socket on the VM-114H2C and to
the mains electricity (not shown in
8. Optional—Press the EDID READ button to acquire or change the EDID
information (see
5.2

Acquiring the EDID

Each input on the VM-114H2C has a factory default EDID loaded
Section 9). This lets you connect the power before having to connect one of the
acceptors.
You can acquire the EDID
• One output (the relevant output LED flashes)
• The default EDID (all output LEDs flash)
• Up to four connected outputs using the Auto-mix Mode
light)
To acquire the EDID:
1. Connect the output(s) from which you want to acquire the EDID.
2. Press the EDID SELECT button briefly.
The device enters the EDID programming mode. The last acquired EDID is
indicated by the lit LED (for example, if Output LED 2 is lit, the EDID
acquired was from Output 2).
3. Press the EDID SELECT button repeatedly until the required EDID is
indicated based on the patterns described above.
1 Another example is the TP-573
2 Another example is the TP-574
3 The VM-114H2C reads the EDID, which is stored in the non-volatile memory
4 This is usually done only once, when the machine is being set up in an installation Once acquired, the EDID is saved in non-volatile
memory and further acquisition is not necessary
5 The EDID acquired is a weighted average of all the connected outputs For example, if several displays with different resolutions are
connected to the outputs, the acquired EDID supports all the resolutions, as well as other parameters included in the EDID
