B.1 Tether Port Pinout
The tether port connector incorporates multiplexed undecoded scanner, decoded
scanner, RS232 serial, and USB interfaces. In order for it to operate, a special wiring
scheme is needed. If you need to create cables for the tether port, contact Psion
Teklogix and request an instruction sheet for tether port termination.
Important: Do not attempt to interface with the tether connector without
direction from a qualified Psion Teklogix technician. Doing
so may cause damage to the 8525 G2/8530 G2 and/or the
tethered device.
