Determining power supply

•

Determining operating mode

•

Select 'Bus' for the first test: MiniTerminal's 'on' message remains displayed and

contrast can be adjusted properly. In 'FixedText' mode, conversely, the 'on' message

disappears after a short time and the relevant fixed text is displayed, which may still

be empty on delivery, in which case nothing appears.

Initial operation

•

Connecting to a PC

•

The MiniTerminal is now ready for operation

Important:

•

(optional power supply see app. section)

Set jumper J9 to the desired operating mode

(open='FixedText', closed = 'Bus').

Connect the stabilised power supply to the clip connector, make sure that

polarity and voltage is correct. A stabilised 5V is required if a voltage stabilizer

is not used.

Configure the potentiometer P1 so that the display can be easily read.

You should be able to read the configuration data:

V<Software Version> T<Display Type> B<Baud Rate>

Example (default setting):

Using the connecting cable and an extension cable if needed (but not a zero

modem), connect the 10-pole CN6 jack to a serial interface (COM1 or COM2)

on the PC

Start the terminal program (transfer parameters: 9600/N/8/2, terminal

emulation 'none' or 'TTY'). Now enter a text as it should be displayed on the

MiniTerminal.

If a 40x2 display is used, the MiniTerminal must first be configured accordingly;

otherwise the display will not be correct:

o to correctly control a 40x2 display, the command sequence

'ESC &S [11]' must be entered, where ESC and [11] are entered as

bytes. To do this, press the Alt key – not the ESC key - and type in the

digits '2' and '7' on the numerical keypad for ESC and '11' for [11].

These characters are not displayed on the screen!

If you are using a voltage stabilizer please read the Power Supply section

Turn power OFF before making any changes to display configuration

Jumper J1; J2 closed
