8. Programmable Inputs and Outputs

Some of the pins on the Digital Out connector can be programmed to accomplish
certain actions. The optional Analog Out connector can be programmed to output
information to an external device.
8.1

Alarm Outputs

The EPOCH 650 includes three dedicated alarm outputs that allow you to control an
external device based on an alarm condition (see Table 23 on page 305). Each alarm
output is a 5 V TTL digital signal that corresponds to the current alarm condition for
each gate. The three gate alarms that can be set are positive threshold, negative
threshold, and minimum depth (see "Gate Alarms" on page 133). When a gate alarm
is triggered, the corresponding alarm output switches from 0 V to 5 V TTL.
8.2

Serial/USB Command Protocol

The EPOCH 650 can be remotely controlled through either the Digital Out connector
or the USB Client port. A comprehensive series of remote commands is available to
allow you access to all functions of your instrument. Contact Olympus for further
information.
Through serial communication over either the Digital Out connector or the USB Client
port, you can connect the EPOCH 650 to a computer for communication with the
optional Olympus GageView Pro computer software.
