| Comment: | U01 is comprised of the Universal OPC Server (UOS) for Serial and TCP/IP Devices and the LD301.PRO device profile. The U01 mnemonic is used to identify this unique combination. UOS will also support many other serial or TCP/IP device profiles. Please refer to our web site for the current list. |
| UOS is a stand-alone OPC Server that can be used with any OPC compliant Client such as Intellution’s FIX® or FIX Dynamics® or OA’s Enterprise Automation software. UOS has many advanced features like: DataView, DataScope, Serial and TCP/IP communications support, and multiple "different" device support. Please refer to our web site for more information on UOS capabilities. | |

Introduction |
| This document provides general information on the device commands supported by UOS and the LD301.PRO profile. If you have installed UOS, you should also review the sections titled About the I/O Driver, How Do I…, Setting up The I/O Driver, and Using the PowerTool in the UOS electronic documentation. To get there, click on Help and Help Topics on the PowerTool menu bar. The PowerTool is a client application with a graphical user interface that accesses the UOS OPC Server and lets you view and modify communications channel, device, and datablock properties. |

| Interface Modules: |
| Device Manufacturer: ANSCO, PO Box 24069, Minneapolis MN 55424 |
| Interface: PRIMM modem, Bell-202 modem for HART protocol, RS-232 port powered. |
| Comment: HART protocol devices such as the SMAR LD-301 Pressure Transmitter requires a modem between the computer serial port and the device network. A PRIMM modem manufactured by Ansco, Inc. was used during testing. |
