The Communication Ports position enables selecting
and programming the serial port of the instrument
–
Serial Port ( RS232 or Bluetooth ).
<ENT>
In case of the RS232 serial port, two parameters should be defined: transmission
speed ( Baud Rate: 1200 , 2400 , 4800 , 9600 , 19200 , 38000 , 57600 or
115200 bits/s) and the time limit during which the data transfer should be
performed ( Time Out ). Other RS 232 transmission parameters are fixed to 8 bits
for data , No parity & 1 Stop bit .
The default value of the Time Out parameter is equal to one second, but this may
be too short for the printers, which are not fast enough. In such cases, the
Time Out parameter should be increased.
In case of Bluetooth, you can set the PIN with the ◄ / ►
keys. Default value is
1234 .
