Appendix C • Remote Control and Monitoring

Introduction

This document provides the guidelines to successfully
communicate and integrate with the MicroVission con-
trol panel.

Networking

The MicroVission supports two different hardware
networks:
• Ethernet: Supporting Modbus TCP and Ethernet IP
protocols
• RS485: Supporting serial Modbus RTU protocol

Communication Wire

For any communication network to work properly, it is
important to use the proper wire.

Ethernet Cable Specifications

For Ethernet communication, the Category 6 cable is
recommended. Many installations now use gigahertz
switches, and category 6 provides greater immunity to
signal crosstalk.

RS-422/485 Cable Specifications
The following cables are recommended for RS-422/485
serial communications.
Although you may elect to use other cables, a low capac-
itance (less than 15 pF/ft.) is important for high-speed
digital communication links. The cables listed below are
all 24-gauge, 7x32 stranded, with 100-ohm nominal im-
pedance and a capacitance of 12.5 pF/ft.
Select from the following four-pair, three-pair, and two-
pair cables, depending on your application needs. All will
yield satisfactory results. It is recommended that you
choose a cable with one more pair than your application
requires.
Use one of the extra wires, rather than a shield, for the
common.
Four-Pair
• Belden P/N 8104 (with overall shield)
• Belden P/N 9728 (individually shielded)
• Belden P/N 8164 (individually shielded with overall
shield)
• Manhattan P/N M3477 (individually shielded with
overall shield)
• Manhattan P/N M39251 (individually shielded with
overall shield)
