5.0.1 Input/Output Jacks
Referring to the different models, the video signal input/output jacks are formed by the 4th row and 8th row VGA female terminals. The audio input/output jacks are formed by the 4th and 8th row 5-phase 3.8mm connection terminals. The VAX-2088 video signal input/output terminal channels are numbered from lower to upper and from left to right as NO.1 to NO.8 channels (in two rows). The video port is the video signal terminal. The audo signal input/output terminal channels are numbered from left to right as NO.1 to NO.8. Refer to the drawing on the housing for port terminals of different models.
Different models of the VAX matrix system provides a different number of input/output jacks for users to connect to different audio/visual equipment including CD/DVD players, graphics workstations, and number displays. The output terminals can be connected to projectors, video recorders, displays and multiplexers and so on.
5.0.1.1 Video Connecting Cable
Data processed by the display card will ultimately be output to the display, and the display output connector bridges together the computer and the display. It is responsible to output corresponding graphics signals to the display. Due to design and manufacturing, the CRT monitor can only receive analog signals, thereby the display card must also be able to input analog signals. The VGA (Video Graphics Array) connector, also called D-Sub conector, is the connector of graphics card for output of analog signals. Although the LCD display can directly receive digital signals, many low-end products still use VGA connectors for connection to the
8
Page 10
VGA card. The VGA connector is a D-sub connector with 15 pins in 3 rows (each row has 5 pins).
Presently, most computers connect with external displays via analog VGA connectors. The computer internally generates digital graphics data to be converted by the graphics card digital/analog converter into the R, G, and B process color signals, and coutour and gamut synchronous signals which are transmitted to the display via the cable. Regarding analog display equipment such as the analog CRT display, the signals are being sent directly to the corresponding processor circuit and drive the controlling Cathode Ray Tube into graphics display. Digital displays such as LCD and DLP are usually equipped with A/D (Analog/Digital) converters to convert analog signals into digital signals. Unavoidably, some losses to graphics happen after two times of conversion from analog to digital and vice versa. It’s understandable to use VGA connectors in CRT monitors, but to use it in LCD displays the quality of graphics display is likely to degrade in the process of conversion.
Different models of the VAX matrix system provides a different number of input/output jacks for users to connect to different audio/visual equipment including CD/DVD players, graphics workstations, and number displays. The output terminals can be connected to projectors, video recorders, displays and multiplexers and so on.
The RCA connecting terminal----audio/video port: The 4-hole RCA Jack is a conventional audio connector. Its installation hole measures 14x18mm.
The VAX Matrix supports various AV signal sources.

5.0.1.2 Audio Connecting Cable
Compared to the video connecting cable, the audio connecting cable has two different ways
of connection: the balanced and the unbalanced connection.
The “Audio Inputs” and “Audio Outputs” connectors of the VAX matrix are for connection
to the video players audio signal and multiplexers.
Balanced connection is a connection method of using two signal wires to transmit a pair of balanced signals. Since interference to two signal wires are similar and out of phase the interfering signals are cancelled out.The lower audio frequencies are susceptible to interference in long distrance transmission. Therefore, balanced connection is a way to counter interference commonly used in professional audio equipment. In household appliances, two-wire cable with sleeve is sometimes used. However, they are used for the left and right audio signal channels and do not belong to balanced connection.
Unbalanced connection uses only one signal cable for connection and is susceptible to interference. Most household appliances and not-so-demanding audio equipment uses unbalanced connection.
A specific connection of the audio signal cable is given below:
1. Unbalanced connection: The “G” leg connects to the Sleeve, and the “+” leg
connects to the red wire (TIP) while the “-“ leg connects to the “G” leg.
10
Page 12
2. Balanced connection: The “G” leg connects to the Sleeve, and the “-“ leg connects
to the black wire (RING) while the “+” leg connects to the red wire (TIP). Refer to Figure 5-3 below:
Figure 5-3 5-Phase 3.8mm Audio Connecting Socket Cable（Balanced/Unbalanced
Connection）
To select balanced or unbablanced connection is often depended on the connectors of the equipment. Use balanced connection as far as possible. Refer to the User Manual prior to connection. Occasionally, you will have to connect balanced connectors of one piece of equipment to unbalanced connectors of another equipment. In most cases, you can use unbalanced connection at the balanced end if quality is not so demanding. If you are demanding for audio quality, you must use a balun to convert a signal from balanced to unbalanced, or vice versa.
5.0.2 VAX Matrix and Control Computer Connection
Use the RS-232 connecting cable to connect the computer serial port (COM1 or COM2) to the RS-232 communication port of the VAX matrix host. The computer can then be used to control the VAX matrix after installation of application software.
Figure 5-4 VAX Matrix and Computer Connection
5.0.3 Remote Control Methods and Settings
The VAX matrix provides standard RS-232 and RS-485 serial communication ports. Aside from using the front panel keys for switching operation, you are also permitted to use the RS-232 and RS-485 serial communication ports for remote operation. It also supports RS-485 serial control.
5.0.3.1 RS-232 Communication Port, Connection Methods
The RS-232 port is a 9-pin female connector. The Leg functions are shown in the table below:

10.0 Common Problems and Solutions
1. What to do if the VAX matrix front panel keys switching not responsive? Answer: The VAX matrix front panel keys employ scanning testing and require longer response
time. Press the keys for 2 seconds and then release. This way, key switching will be responsive in operation.
2. What to do if matrix does not display or color display is abnormal after hot plug? Answer: Switching of the matrix system goes through the IC chips. If the voltage difference
between the input signal equipment and the matrix equipment is too large, hot plug could easily cause damage to the IC chips. Please turn off power to the system before plugging or unplugging.
3. What to do if ghosting happens when VGA signals output to display? Answer: Ghosting is often caused either by the projector, inferior cable quality or long
transmission distance. You are advised to adjust the projector or replace with better quality cable.
4. What to do if loss of color reproduction happens or no video signal output? Answer: Please check if connectors at both ends of the VGA signal cable are correctly
connected.

5. What to do if the serial port (usually refer to the computer serial port) fails to control the VAX matrix? Answer: Check that the communication port set by the control software is correctly connected to
the corresponding serial port of the equipment. Also, check if the computer communication port is in good order.
6. What to do if the corresponding graphics fail to output during VAX matrix switching? Answer: (1) Check if there is signal on the input end. If there is no input signal, it could be that
the input connection cable is broken or the connector gets loosen. You are advised to replace the connection cable. (2) Check if there is signal on the output end. If there is no output signal, it could be that the cable is broken or the connector gets loosen. You are advised to replace the connection cable. (3) Check if the output port number is the same as the controlled port number. (4) If none of the above circumstances happen, it could be internal failure of the product itself. You must send for repair by qualified technical engineers.
7. What to do if the power LED is not on, LCD has no display and no response in operation? Answer: Check if the equipment power input is in good contact.
8. What to do if you sensed power leakage during plugging or unplugging of the audio/video ports? Answer: It could be that the equipment power is not properly grounded. You must properly
ground your equipment, otherwise product life can easily be shortened.
9. What to do if the LCD displays normally and the communication port has return code but no graphics or audio output? Answer: (1) It could be that the audio/video connectors got loosen. Simply replace the
connectors. (2) It could be the connection cable short-circuited. Simply replace the cable. (3) It could be the connection cable is broken. Simply replace the cable.
10. What to do if the VAX matrix panel keys and communication ports are out of order? Answer: Check if the equipment power input is in good contact and the computer
communication ports are in good order. If yes, it could be some internal failure of the
product, please send for repair by qualified technical engineer.
11. What to do if operation and function failure occurred? Answer: Check if the equipment and the matrix system are in proper connection. If the problem
persists, send the product to the maintenance center for repair.
NOTE:
Do not replace the power cord yourself. If the power cord is damaged, ask your distributor to
send qualified technician to replace it for you.
