(See Fig.1.)Theaddress will decrease by one unit each time youpress the (Black) “STEP”push button.If youpress-and-hold the(Black)“STEP”push button,theaddress will decrease continuously,slowly at first,and then faster as you continuetohold the buttonin.(Youdo needtocontinueto hold-in the“TRIPRESET’push button while you do this.)The letter “H” refers to the High 9600Baud rate;and the letter “L” refers to the Low 1200 Baud Rate.An “X”in the Baud Rate field indicates that neither“H”ighnor “L”owBaudRatehas beenselected.Press and release the(Black)‘TEST” push buttontochangethe baudrate.(Youdo needtocon-tinue-to hold-inthe“TRIP RESET”pushbutton.)Suggestion:Beforeyou press and release the(Black)“TEST”push button,setthe“TEST AMPS”switch to“1”,tominimize the effectofan"unin-tendedtest”,which canoccur,if yourotherfingerwould happen tocomeoffthe“TRIP RESET”pushbutton.Note:For correctcommunications,be suretousetheterminating resistor at the endofthetwisted pair(last element in the INCOM®chain).(See Figures11.1,11.2, and 11.3,and referto theIMPACC®WiringSpecification listed in Section 6.)When the address and baudratecode in the dis-play window are correct,release the"TRIPRESET’ push button tosavethe values into theTrip Unit’s non-volatile memory, and the kA,MW orMWh value will return to the display window.Ifcon-trol power is lost, theTrip Unit will still know its(new) address and baud rate.3)4)6)5)F:T*NEffective May 1997
