CONFIGURATION

The USP-S24/48 is configured using a standard web browser (Internet Explorer, Firefox, and Chrome). Enter the USP’s IP address in the Address/ URL bar, typically located at the top of the web browser page, to access the configuration Home Page. Use the links on the left side of the Home Page to access the desired configuration web page.

All configuration settings are saved in non-volatile memory in the unit. Settings are retained when power is removed.

Settings may be uploaded to a computer as a configuration file (.dnf) for storage. Configuration files may be downloaded from a computer into the USP to restore a saved configuration. A configuration file contains all of configuration settings except IP address, subnet mask, and gateway address. Partial configuration upload or download is not supported. The configuration file is a not a text formatted file. It can not be viewed or modified with a text editor.

To access the System Configuration web page, use the following log-on when prompted.

User name: dnfuser

Password: controls

One EVENT IN can trigger more than one ACTION. Select the same EVENT IN on multiple lines and then select an ON or OFF ACTION on each line.

Only EVENTs and ACTIONs associated with the Remote Device’s Device Type or Connection Type will be displayed in the drop down menus. If the desired event or action is not displayed, then go to the Remote Device Assignment web page and change the Device Type or Connection Type for the Remote Device.

In the Event Action and Tally Assignment Tables, the USP-S24/48 keys are identified by their Column, Row position for easy identification. Key number #11 is located in column #1, on row #1. Key number #16 is located in column #1, on row #6. Key number #84 is located in column #8, on row #4.

13. PANEL KEY MAPPER™ APPLICATION

The DNF Controls supplied Panel Key Mapper™ is a small Windows® application that maps USP-S24 and USP-S48 key presses to HOTKEYs for Editors, Graphic devices, Production Playout & Automation systems, as well as other Windows based applications.

For example, map USP-S24 Key: #2 to “SHIFT F3”

#10 to “CTRL SHIFT F10”

#23 to “CTRL ALT F1”

The USP-S24/48 connects to the Windows computer running Panel Key Mapper (pkm.exe) over an Ethernet connection, eliminating USB connectivity issues in mission critical applications.

The USP-S24/48 provides single button control for commonly used functions reducing errors, which saves time and money.

Use the Key Mapper web page to create the HOTKEY key combinations used by the Editor or other Windows applicaton. Use the Event Action Table to map a key press to one or more Key Mapper entries and assign the Remote Device to transmit the HOTKEY to. One HOTKEY can be sent to multiple remote devices.

INSTALLATION

Install the supplied pkm.exe and pkm.ini files in a folder on the Windows computer.

Edit the pkm.ini with Notepad.exe or other simple text editor. (Do not use a word processor.) Change the Panel 1 IP address to the IP address of the USP-S24 or USPS48 that will send HOTKEYs to the computer. Change the Port number from 50000 to any other port number if that port is already in use on the computer.

Add pkm.exe to the computer’s Start Up folder or create a Scheduled Task to launch the application when the computer starts up. Or, using a mouse, double click on the application to launch it. A black box will appear briefly on the screen and then disappear. Check Windows’ Task Manager to confirm that pkm.exe is running.

LOGGING

pkm.exe will create a log file, pkm.log, in the same folder that it resides. Open the log file with a text editor. Each time pkm.exe is launched the log file will show:

04/02/2011, 13:09:41 DNF Control Panel Key Mapper Log 04/02/2011, 13:09:41 pkm.exe startup 04/02/2011, 13:09:41 Console hidden 04/02/2011, 13:09:41 C:\temp\pkm.exe Version 1.3 04/02/2011, 13:09:41 Successfully opened file C:\temp\pkm.ini 04/02/2011, 13:09:41 Successfully processed file C:\temp\pkm.ini 04/02/2011, 13:09:41 Listening on Port 50000 for Panel Key Mapper commands 04/02/2011, 13:09:41 Accepting commands from Panel IP Address 192.168.10.62

where Panel IP Address and Port will reflect the pkm.ini entries.

Every command received from the USP-S24/48 will be logged as follows:

04/01/2011, 23:50:05 Received OID Value: KM_70:1

18. DNF CONTROLS LIMITED WARRANTY

DNF Controls warrants its product to be free from defects in material and workmanship for a period of one (1) year from the date of sale to the original purchaser from DNF Controls. In order to enforce the rights under this warranty, the customer must first contact DNF’s Customer Support Department to afford the opportunity of identifying and fixing the problem without sending the unit in for repair. If DNF’s Customer Support Department cannot fix the problem, the customer will be issued a Returned Merchandise Authorization number (RMA). The customer will then ship the defective product prepaid to DNF Controls with the RMA number clearly indicated on the customer’s shipping document.

The merchandise is to be shipped to:

DNF Controls 12843 Foothill Blvd., Suite C Sylmar, CA 91342 USA

Failure to obtain a proper RMA number prior to returning the product may result in the return not being accepted, or in a charge for the required repair. DNF Controls, at its option, will repair or replace the defective unit. DNF Controls will return the unit prepaid to the customer. The method of shipment is at the discretion of DNF Controls, principally UPS Ground for shipments within the United States of America. Shipments to international customers will be sent via air. Should a customer require the product to be returned in a more expeditious manner, the return shipment will be billed to their freight account. This warranty will be considered null and void if accident, misuse, abuse, improper line voltage, fire, water, lightning or other acts of God damaged the product. All repair parts are to be supplied by DNF Controls, either directly or through its authorized dealer network. Similarly, any repair work not performed by either DNF Controls or its authorized dealer may void the warranty.

After the warranty period has expired, DNF Controls offers repair services at prices listed in the DNF Controls Price List. DNF Controls reserves the right to refuse repair of any unit outside the warranty period that is deemed non-repairable.

DNF Controls shall not be liable for direct, indirect, incidental, consequential or other types of damage resulting from the use of the product.
