Alarm Output Connector Pins; Serial Communication Pins; Encoder Input Pins - Olympus EPOCH 650 User Manual

Ensure the rubber protective cover over the Digital Out connector is firmly closed
before exposing the EPOCH 650 to harsh and wet environments. Always keep the
rubber protective cover firmly closed when no cable is connected.

Alarm Output Connector Pins

The EPOCH 650 includes three dedicated alarm outputs that allow you to control an
external device based on an alarm condition. These outputs are combined with the
Digital Out signals on the same connector (see Table 23 on page 305). Each alarm
output is a 5V TTL digital signal that corresponds to the current alarm condition for
each gate. See "Gate Alarms" on page 133 for details on the gate alarm functions.
When a gate alarm is triggered, the corresponding alarm output switches from 0V to
5V TTL.
In addition to three dedicated digital alarm outputs, the EPOCH 650 also includes a
pulse width modulated (PWM) output. This output is enabled by any alarm condition
on the instrument, and is intended to provide an output to control an external horn or
beeper. The N600-EXTALM (U8780332) external alarm box (optional item) is
controlled by this output and amplifies the alarm beep compared to the internal
beeper included with the EPOCH 650.

Serial Communication Pins

Serial communication allows remote command of the EPOCH 650. A comprehensive
series of remote commands is available to allow you access to all functions of your
instrument. Contact Olympus for further information.
1.2.2.3

Encoder Input Pins

The EPOCH 650 supports single axis quadrature encoder inputs through the Digital
Out connector. The encoder input pins are exclusively supported by the B-scan
feature embedded in the Corrosion Module software option (see "Corrosion Module"
on page 275). The optional Olympus B-scan encoder BSCAN-ENC (U8779522) can be
connected to the EPOCH 650 using the CBAS-10669-0010 (Q7790008) encoder cable.
Other encoders can be supported using customized cables (see Table 23 on page 305
for the specifications of the supported I/O signals).
