DS2/DS4 Hardware Manual
Page 6
3 Introduction
This manual covers the hardware information for the Director product line. It details the standard and
optional hardware, specifications, and information required by the system designer for setting up the unit
configuration. The different models of Director use the same software operating system and are differentiated
from each other simply based on the physical enclosure and hardware platform.
The DS2/DS4 consists of a processor board and base board containing four serial channels. Optional I/O
cards may be added to the board stack via a 16-bit PC/104 header to provide Ethernet, additional
communication channels, analog and digital I/O, or HART protocol ports. All boards are mounted in an
industrial metal enclosure. Director units are provided fully tested and may have customer-specific
configurations when they leave the factory.
By default, the processor board has four serial ports, one of which may be configured for two-wire RS-485.
These four ports are intended for local configuration and programming, and for connection to external field
devices.
The serial ports are configured using the ACE software tool. Using Windows HyperTerminal or another
terminal emulator, one communications port may be used to download the configuration file generated by
ACE and provide diagnostic capabilities. I/O signals from optional I/O boards are cabled from the PC/104
stack using a 50-way header and may be connected to an external breakout device to provide screw
terminations.
