8 I/O Ports
The TR-L100 Reader features four I/O ports. When using the standard STX software application
delivered with the TR-L100 Reader unit, the four I/Os are specifically configured for Industrial
Laundry and Textile Rental applications.
However, if you choose to develop your own software, the four I/O ports can be configured
independently as a general-purpose input or output. Depending on the application software
downloaded in the GemCore
®
OS, the I/O port may command a relay, trigger specific commands
(Windowing…) or read input signals.
8.1 Standard STX Standalone Module
When using the standard STX software application delivered with the TR-L100 Reader unit, the
Standalone module uses the I/O configuration given in Table 3.
Table 3: I/O Configuration in Standalone Module
I/O Port Description
1 Trigger (Input)
2 Copy of Trigger (Output)
3 Active when tag is correctly read (Output)
4 Active when no tag is read after a trigger (Output)
For more information about application software, refer to Section 4.2, "On-Board Application
Software".
8.2 General Purpose I/Os
Each I/O can be configured independently as an input or output.
When an I/O is configured as input, it can be used to connect sensors or industrial logic commands
to execute a specific task. For instance, the TR-L100 Reader can execute a tag Read command
according to the logical level of the input command.
When the I/O is configured as output, it can command a relay or any other transducer.
• Input: Industrial logic (0V to 28V) TTL-compatible.
• Output: Open drain, 250 mA (maximum).
8.2.1 Internal Connections
This paragraph describes I/O electronic schematics when the configuration is set to input or output.
It also gives the characteristics of the V
OUT
supply that is available on the I/O port.
