Chapter 3: Getting To Know Your 7530 G2
Connecting & Disconnecting Tethered Peripherals
52 Psion Teklogix 7530 G2 Hand-Held Computer User Manual
tographers. When pointing at a shiny surface, either shift the bar
code to the side or top, or angle the bar code so that the glare
reflects away from the imager scanner.
Most imagers take several ‘snap shots’ of the bar code in order to
decode it. It is normal for the LEDs to flash two or three times. Hold
the unit steady between flashes to improve decode performance.
• Turn the hand-held computer on. Wait until the unit has booted
up completely.
• Aim at the bar code and press the scan key or the trigger.
• When the scan button or trigger is pressed, a red, oval shaped light (the
framing marker) is displayed. Centre the framing marker in the field –
either in the centre of the bar code you want to scan or in the centre of the
area in which multiple bar codes are to be scanned. Hold the scan trigger or
button until a successful or failed scan result is obtained.
Illumination LEDs flashes (typically several times) and a picture of the bar code(s)
is taken.
3.7 Connecting & Disconnecting Tethered Peripherals
Tethered peripherals such as scanners and printers connect to the hand-held
computer with a quick release, circular connector. When a peripheral is connected to
the hand-held, the unit detects the peripheral and loads the necessary drivers for it.
An icon in the taskbar at the bottom of the screen provides a visual representation of
the peripheral and indicates that it is ready for operation.
To attach the peripheral to the round, tether port on the side of the unit:
• Insert the barrel of the plug into the tether port and rotate slowly until
it clicks into place. The red dot on the port and on the connector should
be aligned.
