GPIO Configuration DIP Switches
Each of the four GPIO Input blocks can be set to either Isolated or TTL
operation using the configuration switches to the left of the terminal blocks.

VIRTUAL DATA CABLE PORTS
The Isolated/TTL configuration switches only apply to the GPIO inputs.
With the switch in the down position, the input is set to TTL. Use this setting
for voltage‑type signals. GPIO inputs set for TTL operation can handle signal
voltages up to 5 Volts.
The up position (Isolated) sets the input to accept on/off switch signals.
Do not use the Isolated setting with voltage-based signals. See the
GPIO Specifications later in this document for additional configuration
information.
GPIO Terminal Blocks
Each GPIO input or output has a positive and negative contact that can
be wired as needed. Four of each are provided. Only a small screwdriver is
required.
RS-232/422 Port
The Pro64 RS‑232/422 VDC port allows a pair of devices to transfer either RS‑
232 or RS‑422 control data (user selectable) at rates up to 57.6k baud across
the Pro64 network. Using Virtual Data Cables for RS‑232/422 always requires
two VDCs because RS‑232/422 data transfers require communicating devices
to be set up in a handshaking pair. Note that RS‑232/422 communication is
point‑to‑point, meaning that a maximum of seven RS‑232 and/or RS‑422
connections (14 total devices) are possible when using Pro64 Virtual Data
Cables.
