Description of the Hardware EPC9 Manual 14
Rear-panel connectors: Three 40-pin connectors and an analog trigger input allow
connection of the EPC9 to other devices:
• Computer-Interface: This is the connection to the Mac-23, AT-16, PCI-16, or
PCI-18 board in the host computer, that allows the computer to communicate
with the EPC9.
• Digital I/O: TTL-level, digital input and output lines are available here for the
control and monitoring of digital signals. See pin assignments in Appendix II:
Technical Data.
• VR10/100: This digital input port is provided by the ITC-16 but is not used by
the EPC9 and its software.
• Trigger In: Input for an external trigger to start data acquisition when the ITC-
16 is waiting for an external trigger. This mode is set in Pulse+PulseFit when
either Trigger Series or Trigger Sweeps is selected in the Pulse Generator.
