Keyboard Interface Problems
Installation of the reader is generally trouble free, but there are some
things to watch for if you are experiencing problems.
Do you have the proper cable?
Most modern computers and terminals use a PC/XT/AT-compatible
keyboard. However, the cable connecting it to the keyboard port may
have variations in either the signal pins or the connector itself. Make
sure that you have the proper cable for the computer/terminal with
which you are interfacing.
Does the keyboard work?
Since the data from the keyboard must pass through the reader, the
cabling connections are correct if the keyboard is operational.
Can the host computer accept the data fast enough?
Some computers and terminals are expecting the data rate from the
keyboard port to come in at a keystroke rate, and might not be able to
accept it as fast as the reader is transmitting. Try adjusting the inter-
character delay to simulate the effects of keystroke delays.
