screws) from the top side of the Carriage Assembly, then remove the Barcode
Reader from the TLS.
7.7.2 Barcode Reader Replacement
This procedure assumes that the barcode reader was removed in Section 7.7.1.
1.
Position the Barcode Reader under the Carriage Assembly, with the mounting
screw holes in the Barcode Reader facing up, and the BCR cable’s plug facing the
cabinet door.
2.
Align the mounting screw holes in the Barcode Reader with the mounting screw
holes in the Carriage Assembly.
3.
Install both BCR mounting screws (6-32 x 1/4-inch Flathead screws) from the top
side of the Carriage Assembly. Use a number 2 Phillips screwdriver to securely
tighten both BCR mounting screws.
4.
Insert a 9/64-inch Allen wrench into the Access Hole in the rear of the Insertion
Axis Motor again.
5.
Gently turn the Allen wrench clockwise, until the Gripper is completely re-
tracted (towards the cabinet door), then remove the wrench.
6.
Connect the Barcode Reader cable to the jack in the back of the Barcode Reader.
7.
Close the cabinet door.
7.7.3 Reconfiguring the TLS for a Different Model Barcode Reader
If the type of barcode reader used in the TLS (model 3600 or 3700) has changed dur-
ing the replacement procedure (Section 7.7.2), the TLS
must
be reconfigured to accept
the new barcode reader.
NOTE
The installation of a Welch Allyn model 3700 Barcode Reader requires that the TLS firmware be
at Revision 1.09 or higher. Enter the Maintenance\Display Revision menu to view the Revision
value; it must be 1.09 or higher. If the Revision value is 1.08 or lower, you must first upgrade
the TLS firmware. This can be accomplished via the SCSI interface, or by replacing the Flash-
PROM as described in this manual or Product Information Note #012.
