4.2.2 Rear Panel User I/O Connector
The User I/O connector exposes a number of internal electrical signals. For
convenience, a number of logic inputs and outputs are included, thereby negating the
need for extra PC based IO hardware. Using the APT support software, these user
programmable TTL logic lines can be deployed in applications requiring control of
external devices such a relays, light sources and other auxiliary equipment, or when
operating a dual NanoTrak application. A 5V supply is required to power the digital
outputs.
The pin functions are detailed in Fig. 4.2 and in each case must be referenced to the
indicated return pin for the signal to be true..
Notes.
* Opto-isolated, TTL level signal.
** For use with digital signals.
† For use with external signal monitoring equipment.
‡ For use with dual NanoTrak applications
