Printercontroller
• In normal operating mode the printer-unit is controlled via the interface RS232
HOST, and the chipreader via RS232 CHIP
• With the command <ESC>6 the ‚transparent mode’ is activated.
The HOST interface path is switched from the printer to the chip-reader
• To switch back the interface path to the normal operating mode, use the
command <ESC>7PRINTER
6.4.3 Electrical connections
The connector ST8 on the CPU-Board is reserved for connecting chipinterfaces.
To connect this interfaces several power-supply pins and the datalines #TXD1 und #RXD1
(see pin assignment ST8) are available.
Please pay attention to connect TTL-level signals only at the datalines. Connecting of
RS-232 level signals (+/-12V) is not possible and will destroy the printer-electronic.
Interface parameters:
Baudrate: 9600 Bd
Dataformat: 8/N/1
Signal level: TTL
Note:
If the ‚transparent mode’ is not used, all interface parameters can be configured freely
(max. Baudrate 57600 Bd)
Baudrate – conversion:
The Baudrate of the ‚HOST’ interface can be selected up to 57600 Bd (see DIP-switch
settings). Since the Baudrate of the ‚CHIP’ interface (transparent mode) is fixed to 9600 Bd
the printer converts baudrates automatically.
Please note, that small delays may arise due to different transmission speed.
