The Modem <strong>Inter</strong>face Unit provides the necessary link<br />
between a modem and <strong>Satchwell</strong> Networking controllers on<br />
a remote site, when using Satchnet Pro Networking<br />
Software. An RS232 input is provided for connection to a<br />
modem on a Wide Area Network (WAN). The MIU is then<br />
able to be connected (via its RS422/485 link) to upto 31<br />
Networking controllers.<br />
FEATURES<br />
• RS232 and RS422/485 ports<br />
• Autoanswer operation on modem sites<br />
• Optional battery backed up Real Time Clock Board<br />
• Allows a further 32 Networking controllers to be<br />
connected, making a maximum of 63 on a single LAN<br />
This Intelligent Advanced Controller is designed for use in<br />
small and large buildings such as office blocks, hotels and<br />
schools. The IAC has a stand alone capability, and may be<br />
configured from a central computer over the serial link.<br />
The IAC has pre-sets to control common applications such as<br />
terminal unit control, VAV and zone control. In addition the<br />
controller can be customised to work on other less common<br />
applications.<br />
The Satchnet software is used to program and monitor the<br />
IAC controllers.<br />
FEATURES<br />
• Compact size allows mounting in a confined space<br />
such as on a fan coil unit<br />
• Serial link<br />
• IACs configured from a computer using the simple<br />
Bubbleland graphical interface<br />
• <strong>Inter</strong>nal software time clock, controller and lighting<br />
time schedules<br />
• Complies with latest European EMC standards<br />
• Switched outputs may be configured as stepped<br />
outputs (including plant rotation), actuator outputs or<br />
outputs for lights and fans<br />
• Six configurable inputs that can be individually<br />
configured as temperature (resistive), analogue<br />
(0...10Vdc) or Digital (Switched) inputs<br />
• 0...10 volt inputs can be used for<br />
humidity/pressure/velocity control or as a reset input<br />
• Resistive inputs can be used for <strong>Satchwell</strong> “T” type<br />
temperature sensors, RPW remote setting units,<br />
Ohms and Light sensors (NORP-12 Light Dependent<br />
Resistor (LDR)).<br />
