2. KEYBOARD PARAMETERS
2.1. Keyboard Number
The keyboard number is determined by the physical connection to
the MV300 switcher.
To observe the present keyboard number, hold down the SHOW
key until the letter ‘n’ appears on the monitor number display. The
keyboard number (1 to 4) will alternately be shown on the camera
number display.
To return to normal operation, depress the SHOW key.
2.2. Beeper Enable/Disable
It is possible to enable or disable the beeper by holding down the
SET key until the letter ‘p' appears on the monitor number display.
This is then followed by either depressing the ON key to enable the
beeper or depressing the OFF key to disable the beeper.
To return to normal operation, depress the SET key again.
2.3. Communication Speed with MV300
The keyboard can communicate with the MV300 switcher at 4
different speeds (ie. 19200, 9600, 4800, and 2400bps).
To see the current speed, hold down the SET key until the letter ‘p’
appears on the monitor number display. This is followed by
depressing the RUN key until the letter ‘b’ appears on the monitor
number display. The baud rate (in abbreviatec form) will then be
displayed on the camera number display (Please refer to Table 1).
The speed of the MV300 switcher can be decreased or increased by
depressing the keys ON and OFF respectively. The communication
speed should be set to match that of the MV300.
To return to nuomal operation, depress the SET key again.

6. ERROR CODE DEFINITIONS
There are two types of error that the keyboard is capable of displaying;
one is where the fault is local to the keyboard and the other is where the
fault is generated from the MV300 Switcher.
6.1. Communication (Local) Error
6.1.1. No Line
This occurs when there are no responses from the switcher.
At this instance, the letters ‘LinE’ will appear on the display.
This error may be due to:
i) Incorrect Baud Rate or communication speed with the
switcher.
ii) faulty I.C. (DS3696)
iii) the connecting cable to the switcher is faulty.
6.1.2. Line Error
This occurs when erroneous data are received and the
letters ‘Lerr’ will be displayed on the keyboard display.
The probable causes are:
i) Incorrect Baud Rate or communication speed with the
switcher
ii) faulty I.C. (DS3696)
iii) the connecting cable to the switcher is faulty
6.2. Operation Error
This error is associated with the MV300 Switcher. A qualified
service personnel is required for the repairing.
This fault usually arises during an operation process, whereby the
letter ‘E’ followed by an error number will be displayed. Refer to the
MV300 Switcher manual (Table 1 of Section 3.21) for definitions of
the error numbers.
