RF Communication Problems
If the RF link device and the printer are not communicating, try each of
these suggestions to correct the problem.
Change or recharge the terminal’s battery.
Have your System Administrator ensure that the following
communication parameters are set on both the terminal and the
printer:
8 data bits
No parity
9600 baud
1 stop bit
DTR flow control (on the printer)
RTS/CTS flow control (on the terminal).
NOTE: The application on the terminal should be written with the
parameters built in.
Re-link the printer and RF link device.
Move the modules closer than three meters apart.
Move the RF link device and printer around to find the best relative
position between the two.
Swap in new devices (printer or RF link device) to narrow the problem
down to a particular device.
Make sure no other RF devices are within the 20-foot zone because
they may obscure the intended linking.
