5.2.2.1.
RS232_Reader (ATM)
RS232 ATM connection may be used to connect RS232 devices to the Access Touch 2.0.
Note:
By
default, any pre-installed Access Touch 2.0 internal reader uses this connection, Therefore you
should connect devices to this port only after any internal reader has been disconnected from it.
Data from this RS232 connection routes through the Access Touch 2.0 application controller.
Consult the separate Access Touch 2.0 Protocol Description for RS232 ATM device output.
Corresponding data routes through the
/dev/ttyS1
port in the Access Touch 2.0 Embedded Linux
Operation System.
5.2.2.2.
RS232_COM (ETX)
The RS232 ETX connection may be used when connecting a second RS232 device to the Access
Touch 2.0. This connection may also be used if the primary RS232 ATM port is unavailable. This
hub is connected directly to the ETX- e COM module.
Data from this connection may be routed through the
/dev/ttyS0
port in the Access Touch 2.0
Embedded Linux Operation System.
5.2.2.3.
Speaker
A speaker may be attached using the SPKR- R connection. By default any built-in speaker also
connects to this hub.
5.2.2.4.
Microphone
Microphones can be connected via the MIC connection.
