1. ULI BOARD WIRING INSTRUCTIONS V1 2 Thank you for your ULI Board purchase The ULI Software and Documentation are available for download at http www ilinkboards com ULI1 2Files zip The Docs will take you step by step through the software installation and usage The board comes ready to operate and does not require the software for initial set up To set up advanced features such as the timeout timer CAT control etc the software will be needed To test the board run the ULI Test Software and to make advanced changes run the ULI XP Setup For all platforms To run the setup software copy the zip file to a blank folder on your computer Name it uliboardsetup Then unzip the file into that folder Now run the setup exe file Regular updates to the software and other information will be available through the ULIBOARD Yahoo Newsgroup USING THE MONO JACKS ON THE BOARD 1 Make up a microphone connector to your rig that has two shielded cables one carrying the PTT with PTT Ground and the other the Microphone Audio with Microphone Ground These cables will be terminated with mono 1 8 male plugs on at least one end Insert the PTT plug into the PTT Jack on the rear panel of the ULI board and the MIC Audio cable plug into the TX Mic jack on the front panel If you are using a COS connection make a third cable terminated with a 1 8 plug install it from your receiver into the mono COS in jack on the front panel The COS signal can no2. his can be plugged into the COR jack Note this will over ride rig COR output from a rig connected to the RJ45 Set the Threshold to about 2v and leave the box unchecked The following information is included online ULI Software Doc Instructions Kit Instructions Schematic Block Diagram Parts List WinPSK31se Please visit our web site for more information or contact me at wb2rem amsat org I have also setup a software help page at http www ilinkboards com echolinksetup html In addition please notify me of any irregularities As usual PIC upgrades will be done for free when the PIC chip is sent back with a SASE 73 JIM WB2REM and TERRY G4CDY
