Connecting through the Parallel Interface

This section explains how to connect I/O to the F160 through its parallel inter-
face to input signals such as measurement triggers or output signals such as
measurement results.
Either the I/O terminals or I/O connector can be used for the parallel interface.
The I/O terminals and I/O connector cannot be used simultaneously.
I/O Terminals
When the required control signals are being connected to the I/O terminals,
attach the control wires to the included connector (Phoenix MC1.5/10-STF-
3.5) and then insert the connector into the F160.
I/O Connector
When you want to use the parallel interface to input commands and output
measurement results, prepare a parallel I/O cable and connect it to the I/O
connector. Refer to the Communications Reference Manual for details on com-
munications settings and I/O formats.

I/O Terminal Connections

Wire the cable carrying the control signals to the connector that was included
with the F160 and insert the connector into the F160. The following diagram
shows the I/O allocation of the F160's I/O terminals. Just wire the terminals
that are needed.

Precaution
Do not input the RESET input immediately after turning ON the power. When
using RESET input to synchronize startup timing, wait at least 1 s after turning
ON the F160's power supply before turning ON the RESET signal.
CHECK
Use a DC power supply with countermeasures against high voltages (safe
extra low-voltage circuits on the secondary side) for the COMIN terminal. If the
system must meet UL standards, use a UL class II power supply.
