6.1 External Bar Code Readers
6.1.1 PowerScan
®
Standard, LR and XLR Bar Code Scanners
The 7535 G2 supports Psion Teklogix’ PowerScan
®
industrial bar code scanner with stan-
dard, long range and extra long range options.
To connect this scanner to the 7535 G2, attach the device to the tether port at the upper-right
side of the 7535 G2. Before using the bar code reader, you may need to change some param-
eters (see “Non-Decoded Scanners” on page C-55). Review your Power Scan Programming
Guide (PSC) for details.
6.1.2 Entering Data With The Bar Code Reader
For external non-decoding scanners, when a label is scanned successfully, the 7535 G2 will
beep if configured appropriately and the scan LED will flash. (Most external decoding scan-
ners have their own indicators—some communicate with the unit.) Occasionally, the bar
code labels are poorly printed or damaged and cannot be read properly. In this case, use the
keyboard to enter data from the label.
6.2 RD7950 Integrated UHF RFID Reader
The RD7950 UHF RFID Reader is an EPC-compliant RFID reader available for Psion Tek-
logix rugged hand-held computing devices. The RD7950 can be retrofitted to deployed

RFID with existing technologies such as laser bar code scanning or imaging.
