Testing Communication using NON PORTABLE mode
Testing communication between a serial interface TriCoder and a PC needs
some kind of software to read the serial port. If using a dumb terminal/host
configuration, the testing is almost identical to that of a PC keyboard
wedge. To establish communication between a serial TriCoder and its host,
go to
Chapter 3 ; Non Portable Mode for detailed instructions. The key to
testing communications is to keep it simple – you don’t want to have to
determine whether it’s your software or the TriCoder causing a problem.
Keyboard Wedge Interface (not USB)
Connecting the Hardware
The TriCoder can operate as a keyboard wedge on both a PC and a
Macintosh. A simple cable and configuration change is all that is needed.
PC Keyboard Installation (does not apply to USB)
To install the TriCoder as a keyboard wedge, use a Splitter cable, F30/1 for
the PC. Use the following procedure and the diagram on the following page
to install the TriCoder between the keyboard and computer:
1. Before unplugging or plugging in anything , the computer must be
turned OFF . With the power OFF, locate the cable coming out of
the keyboard and follow it to the back of the computer where it
plugs in. Unplug the keyboard cable, look at the connector and
note whether it is large and has 5 pins or small with 6 pins. Take
the F30-1 Y cable and check whether the female end of the cable
matches (5 pin or 6 pin) the male end of the keyboard cable. If it
does not, remove the adapter from the Splitter cable (it may be on
either end), flip it over and place it on the correct end. You should
now have the two ends of the Splitter cable and the keyboard cable
all with the same size connector.
