SETUP PARAMETERS, cont'd.
Contrast
Serial Communication
• Baudrate
• Parity
• Character Length
• Stop Bits
• Flow Control
• New Line
This chapter explains the meaning of the various setup parameters.
There are several ways to change the setup:
• By means of the Terminal Setup option in UBI Shell, see the UBI
Shell Standard Startup Manual.
• By means of setup files or setup strings. See the UBI Fingerprint
Reference Manual, SETUP statement, or the UBI Direct Protocol
Programmer's Guide.
The contrast setup allows you to make minor adjustment of the
printout in regard of blackness, e.g. to adapt the printer to variations
in quality between different batches of the same paper quality.
The serial communication setup controls the communication between
the printer and the connected computer or other devices on
the standard serial channel "uart1:".
The serial communication setup has no consequence whatsoever
for parallel communication via an optional parallel interface
board.
For the serial communication channel, the following parameters
can be set. Make sure they match the setup of the connected device
or vice versa. The default setup (indicated by bold characters below)
is selected as to make the printer understand and act upon UBI
Fingerprint instructions transmitted from the host, regardless how
the host is set up. If the setup of the printer and the setup of the host
do not match, the response from the printer to host will be garbled.
• Baudrate:
The baudrate is the transmission speed in bits per second. The
following baudrates can be selected:
300
600
1200
2,400
4,800
9,600 Max. recommended baudrate for 20 mA current loop
19,200
If communication problems occur, try a lower baudrate.
