PCI20EX PCI Express (Pcie)
PCI20EX PCI Express (PCIe) Bus ARCNET® Network Interface Modules INSTALLATION GUIDE INTRODUCTION The PCI20EX series of ARCNET network interface modules (NIMs) links PCI Express (PCIe) bus compatible computers with the ARCNET local area network (LAN). Since most PC motherboards have migrated from the legacy PCI and PCI-X Bus, a PCI Express style NIM is required. The PCI20EX series is compliant to the PCI Express Card Electromechanical Specification Revision 2.0 and both standard height and low-profile brackets are provided. The PCI Express interface allows for jumperless configuration and Plug and Play operation. The module operates with either an NDIS driver or a null stack driver in a Windows® environment. The PCI20EX incorporates the COM20022 ARCNET controller chip with enhanced features over the earlier generation ARCNET chips. New features include command chaining, sequential access to internal RAM, duplicate node ID detection and variable data rates up to 10 Mbps. Bus contention problems are minimized since the module’s interrupt and I/O base address are assigned through Plug and Play. The PCI20EX exploits the new features of the COM20022 which includes 10 Mbps communications utilizing the various EIA-485 transceiver options. Each PCI20EX module has two LEDs on the board for monitoring network operation and bus access to the module. It is equipped with an 8 position, general purpose DIP switch typically used to assign the ARCNET node address. Ultimately, the node address is configured via software so the DIP switch can also indicate user-defined functions such as data rate, cable interface, or master/slave status of the system. -

Openbas Application Manual
LT-6617 Rev. 1 Application Manual July 2017 Table of Contents 1.0 Frequently Asked Questions 4 2.0 OpenBAS Wiring Guidelines 6 3.0 OpenBAS-HV-WLSTH Wiring 9 4.0 Glossary 11 3 1.0 Frequently Asked Questions 1.1 What is a Building Automation System? Building Automation Systems (BAS) are centralized, interlinked networks of hardware and software which monitor and control the environment in industrial, commercial, or residential applications. While managing various building systems, the automation system ensures optimal operational performance of the facility, comfort and safety of building occupants, and increases energy efficiency. 1.2 What is OpenBAS? Mircom’s OpenBAS (Building Automation System) is a wide selection of UL/ULC listed controllers and supporting accessories that can be easily integrated into any industrial, commercial, or residential applications. OpenBAS delivers HVAC (heating, ventilation, and air conditioning), Lighting, Power Metering, and VAV Fan & Coil control to optimize comfort and energy management within a facility. OpenBAS controllers are programmable and configurable with advanced functions to accommodate any custom application. 1.3 Which systems in a building can OpenBAS control? OpenBAS delivers HVAC (heating, ventilation, and air conditioning), Lighting, Power Metering, and VAV Fan & Coil control to optimize comfort and energy management within a facility. 1.4 Is OpenBAS recognized by any listing agencies? OpenBAS equipment is certified by listing agencies, such as: UL, ULC, CSA, and FCC. 1.5 How many PLCs (Programmable Logic Controllers) can I have on my network? Depending on the network type, different capabilities are offered. TCP/IP networks have the number of devices limited by the number of IP addresses available on each network; however, routers can be used to span multiple networks allowing an unlimited number of devices. -

FFU-HE High Efficiency Fan Filter Unit
FFU-HE High Efficiency Fan Filter Unit Price High-Efficiency Fan Filter Units (FFU-HE) are the most energy efficient line of fan filter units (fan filter modules) on the market today. Designed specifically for use in cleanrooms, pharmacies, pharmaceutical manufacturing facilities and laboratories, the FFU-HE delivers high volumes of HEPA (or ULPA) filtered air at low sound levels while reducing energy consumption by 15 to 50% versus comparable products. Typical Applications Fan Filter Units are used in critical FFU-HE, Roomside FFU-HE, Bench Top Removable Filter Replaceable Filter applications such as healthcare, Ducted Inlet Non-Ducted pharmaceutical compounding, or microelectronics manufacturing. With the integrated HEPA or ULPA filters, ultra-clean air is delivered with a unidirectional vertical downward airflow pattern into the space. The integrated high efficiency motors are designed to overcome the static pressure of the filter, and are ideal for retrofit applications where the FFU-HE Filter Options air handler is not able to provide the required static. Product Information FFU-HE is available in 24x24, 24x36 and 24x48 modules, in both aluminum, stainless steel and hybrid construction. Both PSC and EC motors are available, and have been optimized for industry leading energy efficiency. HEPA filters are typical, while ULPA are available as an option. FEATURES AND OPTIONS High Energy Efficiency • High Energy Efficiency • Industry leading energy efficiency means lower operating costs, potentially saving thousands of dollars in electricity per year. • High Airflow Capacity • Energy consumption as low as 55 Watts at 90 fpm (2x4 module) • Complete Control and • See performance data for specific energy consumptions Monitoring via BACnet High Airflow Capacity • Roomside Removable • High airflow capacity per unit means fewer units and lower first cost (RSR) filter • Active filter area is maximized with the Bench Top Replaceable (BTR) filter, with 2x4 units able to achieve up to 930 CFM.
