breff Posted October 3, 2006 Share Posted October 3, 2006 No need for pull ups on 9800 if using bell trigger. The opinions I express are mine and are usually correct! (Except when I'm wrong)(which I'm not) Link to comment Share on other sites More sharing options...

Guest Posted October 3, 2006 Share Posted October 3, 2006 old you was right on this one and that to be honest shocked me, i assume you wired the bell and the dialler in series mate!!lmao Whats more shocking is you state i was right this time, have i been wrong everyother time? , or not to be possibly Link to comment Share on other sites More sharing options...

arfur mo Posted October 4, 2006 Share Posted October 4, 2006 right arfur's gone and got his shotgun out of the closet 9800 SAB neg trig can be 'overcome' when not driving by the externall siren (depends on model) neg voltage being backfeed from the 'ringing' input, causing a 'floating voltage' not distinct enough to allow a 100% switching everytime on every operation. again dependent on dialler (pyronox as example) they need a clear 'high to low' sisgnal for reliable operation - the 9800 need 'asistance' in this for the digi output, the strobe output and the programmable outputs. so click of rusty trigger and blaammmm!! up to you james and OH, but like with iD and screened cable - if it aint broke don't fix it regs alan If you think education is difficult, try being stupid!!!!

arfur mo Posted October 4, 2006 Share Posted October 4, 2006 It does strike me as strage that the digipins, dont have pull ups on them as i thought it was a design standard of the molex foot print. hi James, these days its only loaded with gunpowder - not shot :'( as for the molex pins, makers (i'd assume) put their own 'bias ressister' on the piggyback board, with wired inputs anyone can liturally stick in any device they like. regs alan If you think education is difficult, try being stupid!!!!
