SELF CHECK SYSTEM

1. Purpose of Self Check System

8
This Self Check System for the System Controller WV­CU550 and the Matrix Switcher WJ-SX550 was designed for testing the WV-CU550 and each Board of the WJ­SX550 perfect in the Production line. However, many of the procedures included here can be used for the field service.
8
This Self Check System does not require a fully config­ured System for testing. However, one of each of the fol­lowing Boards are required: CPU Board, Control Board, Alarm Board, Video Input Board and Video Output Board.

2. Execution Procedure of Self Check System

2.1. The execution of the Self Check System can be con-
trolled by either the 10-Key of the WV-CU550, the Test Switches on the each Board, RS-485 line or RS­232C line. Depending on how Instruction codes are input to the System either 2-digit or 3-digit codes are used.
2.2. It is possible to use a Personal Computer for checking
the CPU Board, Control Board, Alarm Board and Video Output Board of the WJ-SX550 and WV-CU550 after connect the Personal Computer to the RS-232C Connector on the CPU Board of the WJ-SX550. A 3-digit Instruction code is used. However, when entering Instruction Codes directly on the Board through the use of Dip Switches, A 2-digit code is used.
2.3. It is possible to check the CPU Board, Control Board,
Alarm Board and Video Output Board of the WJ­SX550 by use of the WV-CU550. A 3-digit Instruction code by the 10-key of the WV­CU550 is used. However a 2-digit Instruction code is used with the WV-CU550 self check.
2.4. Different ways of entering to the Check Mode:
1) Enter the Check mode by turning On the Power Switch after setting the Test Switch on each Board or the WV-CU550.
2) Enter the Check mode by the Check Program Execution Request message from the Personal Computer during normal operation.
3) When using the WV-CU550, the WV-CU550 trans­mits the Check Program Execution Request mes­sage to the CPU Board of the WJ-SX550.
8
The CPU Board transmits the Check Program Execution Request message to the WV-CU550 and to all the Boards of the WJ-SX550 if the CPU Board has received the Check Program Execution Request message.
8
The Check Program Execution Request message is "STX CPS ETX".
2.5. The Self Check System is ended when the Power
Switch is turned off.
2.6. Self check through use of Test Switches alone:
8
The Microprocessor of the CPU Board controls and checks some items of the Control Board, Video Output Board and Video Input Board, therefore these three Boards should be controlled by the CPU Board for a more complete check.
