3.1 Usage Precautions

 System should be installed in a clean environment and has a prop temperature

and humidity.

 All of the power switches, plugs, sockets and power cords should be insulated and

safe.

 All devices should be connected before power on.

3.2 Connection Diagram

4. Control Operations

4.1 Front Panel Button Control

Users can control VMX-8 rapidly and directly with its front panel buttons. Here is a brief
operation guide to front panel buttons.

Format: “Input Channel” + “Switch Mode” +“Output Channel”

Note:

1) “Switch Mode”:

AV: Transfer AV signal from AV signal card& audio signal from audio card
synchronously

Video: Transfer AV signal from AV signal card
Audio: Transfer audio signal from audio card.

2) “Input Channel”: Fill with the number of input channel to be controlled,

3) “Output Channel”: Fill with the number of output channels to be controlled. Press

“All” to select all the outputs.

4) The input/output channels on the rear panel are counting from left to right, top to
bottom.

5) The input delay time between two numbers of every input& output channel must be
less than 5 seconds; otherwise the operation will be cancelled.

Example:

1. To transfer input 1 to output 1, press input “1”, output “1”.

2. To transfer signals from input 1 to all output channels, press buttons in this order:

“1”, “All”.

Functional Buttons:
UNDO button: return to the previous status

Example: Input 6 is connecting with output 6, press input “6” + “AV”+ output 4 to
change the connection. Press “Undo” to enable input 6 to reconnect with output 6.

 button: If you press buttons “1”, “AV”, “2”, “” in order, then “2” will be canceled.
THROUGH button: get straight I/O connection, e.g. input 1-> output 1, input 2-> output

2.

Press “Input Channel” + ”Through”
Example: If you press buttons “ALL”, “THROUGH” in order, then the result will be like

input 1 output 1, input 2output 2, input 3output 3 … input 8output 8.

4.2 IR Remote Control

With the IR remote, VMX-8 could be controlled remotely. As the function buttons on
the IR remote are the same with the ones on the front panel, the IR remote shares the
same operations and commands with the control panel.
Press the buttons under below format:

“Input Channel” + “Switch Mode” +“Output Channel”

4.3 RS232 Control

4.3.1 Connection of RS232 Communication Port

Except the front control panel and IR remote, VMX-8 can be controlled by far-end
control system or through the Ethernet control via the RS-232 communication port.

This RS-232 communication port is a female 9- D connector. The definition of its pin
layout is shown in the table below.

When VMX-8 connects to the RS232 port of a computer with control software, users
can control it by that computer. To control the switcher, users need to use RS232
control software.

4.3.2 RS232 Communication Commands

With this command system, users are able to control and operate the VMX-8 with
RS232 software remotely.

Note:

 Please disconnect all the twisted pairs before sending command

EDIDUpgrade[X].

 Type the command carefully, it is case-sensitive.
 Commands pertaining to EDID only avails for signal cards that support EDID

management.

 VMX-8 boasts 6 in-built EDID data, the chart below illustrates the detailed

TCP/IP default settings: IP is 192.168.0.178, Gateway is 192.168.0.1, and Serial Port
is 4001. IP & Gateway can be changed as you need, Serial Port cannot be changed.

 Controlled by Single PC
Connect a computer to the TCP/IP port of the VMX-8, and set its network segment to
the same as the default IP of the VMX-8 (192.168.0.178).

14

Modular Matrix Switcher 8x8

 Controlled by PC(s) in LAN
The VMX-8 can be connected with a router to make up a LAN with the PC(s), this

make it able to be controlled in a LAN. When control, just make sure the VMX-8’s
network segment is the same with the router. Please connect as the following figure for
LAN control.

Step1. Connect the TCP/IP port of the VMX-8 to Ethernet port of PC with twisted

pair.

Step2. Set the PC’s network segment to the same as the VMX-8. Do please

remember the PC’s original network segment.

Step3. Set the VMX-8’s network segment to the same as the router.
Step4. Set the PC’s network segment to the original one.
Step5. Connect the VMX-8 and PC(s) to the router. In the same LAN, each PC is

able to control the VMX-8 asynchronously.

Then it’s able to control the device via a TCP/IP communication software.
