3.2.1 RF Channels
The TR-L100 Reader can drive up to two antennas with each channel able to drive up to four
watts. LEDs indicate which RF field (channel) is transmitting (green).
3.2.2 Synchronization Input/Output
When configured for input, this BNC connector makes it possible to use an external 27.12-MHz
clock to generate the RF field, instead of the internal clock generator.
When configured as output, this connector can drive other TR-L100 readers and provide the
27.12-MHz clock.
The Sync LED indicates the clock mode:
• Red: The internal clock generator is enabled and an external clock signal cannot be input.
• Green: The internal clock generator is disabled. A 27.12-MHz clock signal must be
connected to the Sync In/Out connector.
By default, the internal clock mode is applied and the Sync In/Out connector is configured as an
output. If the external clock mode is required, contact your TAGSYS sales representative for
specific configuration information.
3.2.3 I/O Port Connector
The TR-L100 reader provides four Input/Output (I/O) ports. Each I/O can be independently
configured as an input or output by the application software.
When configured as outputs, I/Os are open drain (250 mA). A pull-up supply must be connected to
the I/O port reference input (V
IN
). The pull-up supply voltage range is between 5V and 28V.
When configured as inputs, the I/O input signal range is between 0V and 28V.
I/O port LEDs indicate whether the I/O is configured for input (green) or output (red).
Please refer to Section 8, "I/O Ports" for more information.
3.2.4 Init Button
The Init button aborts the embedded application stored in the Data Processing Unit memory. The
TR-L100 Reader is then ready to be downloaded with a new application.
3.2.5 Serial Connector
The serial connector is used to communicate with an external environment. User commands and
data exchanges are transmitted through this port that can be set to RS-232, RS-485 or RS-422
mode by the software. Different baud rates can be defined for each mode.
CAUTION: The antenna MUST be connected to the reader before the unit is turned on.
Industrial I/O ports can only be accessed via the Data Processing Unit (DPU).
The TR-L100 Reader must be switched off and then back on before an embedded
application takes effect.
