Hi group,
Im planning to build a new project and I need information about Zetron 45/48. First, the controller is Zetron 45B but I swap the firmware U3 and U4 to transform into model 48. My firmware version is 6.93 and I can do DCS, SMDR Print, SMDR Storage, DTMF, 2 Tone, 5 Tone and 325 Users. I want to activate the SMDR Storage option and program date and hour into the unit. Into Z48 manual, Zetron recommend to Change U5 IC to SMDR Memory IC, maybe somebody on the group know the number of this IC? Maybe it is just a Smart Socket like U6 with a real clock IC. The Smart Socket on U6 is a DS1213C. At this moment U5 number is Toshiba TC5565ALP15 and if I go to the Test Option and run Test Memory Z48 respond BAD:SMDR Another question, can we bypass the back-up battery into the Smart Socket like DS1213 with other external battery? Zetron sell the Smart socket ±70$ and I saw on Maxim web site for ±15$. It is very appreciated if somebody of you have hint to bypass the expensive Zetron kit option. You can contact me off list at this address (mour at sympatico dot ca) Thank you and 73 Eric
