Connect a serial cable between the serial port of the computer and the female DB9
connector of the master control unit (VB1).
Connect the PS2 keyboard to the master control unit.
Configure the HyperTerminal on the computer using the following settings:
–

Configure the ASCII settings as shown in
Power-up the master control unit, the LED panel and also the slave control unit (if
connected).
The LCD on the master displays the menu program which shows “Press F1 for PC-
UARTComm”.
Press the F1 key on the keyboard attached to the PS2 connector of the master control
unit.
The HyperTerminal shows the message
–
–
Enter the slave control unit address (as seen on the LCD of the slave control unit) or
the address of the master (255), and then press the “Enter” key on the PC keyboard.
Addresses allowed are between 1 and 255.
If the entered address is not present there is an error message on the HyperTerminal,
“Address Mismatch; enter display board address”. Check the address of the slave
board and then re-enter it on the HyperTerminal.
When the address is matched, the message on the HyperTerminal is “Enter no. of LED
boards”. Enter the number of LED display panels connected in cascade to the selected
control unit (one LED display panel constitutes 16x32 LED's). A maximum of 8 panels
can be connected to any one control unit.
The next message is “enter mode; Entr between 1-9”. This is for entering one of the 9
display modes. These are the following:
