Model Changes – from Serial to Wedge & back
All that is required to change a serial model TriCoder to a Wedge model
TriCoder (or wedge to serial) is to simply move a block of jumpers inside
the TriCoder and change the cable. Although this sounds like an easy
change to make, it is not necessarily a convenient one. It is especially
advantageous for Dealers (they only have to stock one model) and for the
user who utilizes the TriCoder as a wedge for most of the year, and changes
to serial only occasionally to do an inventory or other periodic activity.
The serial interface is much faster for uploading large files. If you find
yourself changing back and forth from serial to wedge quite often, you may
want to consider investing in another reader or using Portkey with a serial
reader to get keyboard wedge-like operation. As with the Firmware
Upgrade, use these precautionary measures when changing the interface:
•
Upload all data and programs from the TriCoder.
•
Turn the TriCoder off and unplug the AC power adapter.
Follow these steps to change the interface:
1. Open the TriCoder and lay the two halves flat as shown below.
2. Referring to TriCoder diagram
above
, locate the
Keyboard/Serial
jumper positioned next to the two RJ45
scanner and computer ports. The jumper block is
9
positions
long and has
3
rows of pins.
