Turn RV1 (contrast) fully anti-clockwise.
Set dipswitches SW1 (mode) to the ‘off’-position.
Set jumper SK3 for ‘cable’-operation but do not connect a serial cable
Connect the supplied wired female connector to SK8
Apply power (for power requirements, see pag. 10)
The LCD should initialise and the following text should appear :
K8045 Vxxxxxxxx (‘x’ indicates software version)
If the message ‘EEPROM FAILURE’ appears, check the position of IC2 and/or
re-check the complete assembly
Next, the display will show : 1 2 3 4 5 6 7 8
Check input 1 by shorting the left hand brown and the black wire. An ‘x’ appears
next to the ‘1’ on the screen, indicating ‘input active’
Check all inputs (brown to grey) in a similar fashion.
Next, flip dipswitch 2 of SW1 to the ‘ON’ position.
The display should display ‘9’ (the ninth message is displayed when no inputs
are active). Repeat the input test as above, but now the display will show the
active input only
RS232 interface setup :
Hook-up a serial cable (for details, see pag. 11) between a free serial port of
your computer/terminal and the K8045. You can download free software from
our website www.velleman.be, which allows you to transfer messages from the
PC to your K8045 and which allows you to display messages on you K8045.
You can also use a terminal or terminal emulation program to manually enter
messages. Terminal settings are :
Baudrate : 2400
Parity : none
Databits : 8
Stopbits : 1
