USING THE TEST PROGRAM
Set RF Output Power
Enter the desired RF output power as a percentage of the maximum power into the Set
Power box. Click the set Power button. (Note: the actual maximum Radiated RF Power is
factory set to comply with the radio regulations in the country of use. In the USA and
Canada this is 4 Watts EiRP).
Set Beam
The beam direction may be pointed to any desired direction within ± 30 degrees of a line
perpendicular to the centre of the SASL antenna panel. When looking in the direction of the
beam (as if through the SASL), and with the SASL orientated with the arrow upwards, Phi
+ve angles are up, -ve angles are down. Theta +ve is left and –ve is right. Enter the
steering angles Theta and Phi in the respective boxes and click set beam.
Read Tags
Click the Inventory button. Tag UII (EPC code) followed by the Received Signal Strength in
dBm will be shown in the window for each tag identified. If there is more than one tag, then
each tag identified will be shown on a separate line. Click the Repeated_Inventory button
to repeatedly query for tags present in the SASL beam. This function is useful for identifying
tags that are moving.
APPLICATION INTERFACE
The SASL uses an International Standard, Application Program Interface (API) as defined in
ISO/IEC 24730. Further details of the API and commands are contained in the Programmer’s
Reference Guide.
