TROUBLE SHOOTING

This section describes problems commonly encountered during system start up
13.1

An S1566 Reader malfunction

If the reader stops to communicate with the Host or indicates malfunction in any way, the reader
shall be replaced with a new reader. The non functional reader is to be sent back to TagMaster.
WARNING The TagMaster reader must NOT, under any circumstances, be opened to be
checked for errors. There are no replaceable parts inside. TagMaster takes no
responsibility for the consequences if the reader is opened by unauthorised personal.
13.2

Unsuitable interface converters

Connecting RS232/RS85 converters to the Reader port A or B requires intelligent converters i.e.
converters that can switch between receive and transmit dependent of the information flow
direction.
13.3 Interference
If more than one Reader is used in closed vicinity of each other, they must be set to different RF
channels. Neglecting to do this will reduce communication range.
13.4 Using wrong address
When many Readers are controlled by one host in a polled network, different Reader addresses
must be used. Neglecting this will cause serious communication problems in the network.
13.5 Forgetting the free-wheel diode across inductive
loads
Inductive loads connected to the Communicator digital and relay outputs must be provided with
a free-wheel-diode to prevent malfunction or damage of the Communicator.
13.6 Using different data speed in the Tag(s) and in the
Reader(s).
A Reader operating at high data speed can not communicate with Tags set to low data speed and
vice versa.
