TROUBLESHOOTING

READER IS SLOW TO RESPOND

If the Desktop Reader pauses for a second or longer before responding to a command sent to it then the USB

connection may be introducing excessive voltage loss. The Desktop Reader pauses to allow an internal power

store to be recharged before doing a transponder read. A voltage drop in the cable used to connect the reader

slows down the recharge. For best performance the USB cable used should be short, good quality and not

connected through an unpowered hub.

USB SERIAL PORT NUMBER TOO HIGH

In some cases where there have been a lot of other devices installed on the host computer the UHF reader may

be given a Virtual Com Port (VCP) with a higher number e.g. COM35. Some applications are unable to connect to

com ports greater than 16. To resolve this, navigate to Device Manager from 'Start>Control Panel>Device Manager'

(or one of the many alternative ways). Expand the section 'Ports (COM & LPT)' to see a list of the available ports.

Right click on the Reader port and select 'Properties', then the 'Port Settings' tab and the 'Advanced button' to get

to the screen shown below:

Select a spare COM port number below 16. This may still show as 'In use'. So long as the device that was using it

has been disconnected it is safe to ignore the warning and click 'OK' to complete the change of port.
