I had a problem similar to yours in gaining access to some older Zetron 38A controllers. I found that the RAM where the access code was stored was battery backed up using a Dallas Semiconductor battery back up chip. I found that I could remove the RAM chip from the battery back up chip and the access code would reset to factory default. After a few minutes, plugging the RAM chip back in resulted in a reset to the original factory access code, and factory parameters. From there is was follow the manual to set them up to the parameters I wanted. 73 - Jim W5ZIT

I recieved several replies from the group but nothing seemed to work. Fortunately we were able to pull the chip out of one I had, read and copy copy it and insert it into my friends unit to get it working again. Below is copy of a procedure that I recently forwarded to another friend with a CSI-32 who had a similar prolem, this will work with out copying someone elses chip, (The info below should be edited and posted in the CSI section of the RB site for future reference.) This may also work on the CSI-32 super and CSI-32Plus as well. "The link below will take you to the Repeater Builder Website and the .PDF file for the CSI- 32 Controller Manual. If you don't have a copy of the manual, print out a complete copy for yourself first. Then carefully read paragraph 5.10 on resetting the Programming Access Code. The Default setting is"35687". It states that you can only change the last 2 digits of the code, however you can also use the A,B and D characters from the 4th row of the DTMF pad in the modified the access code string. If you can't enter the program mode using the Default No. 35687 then enter "35600" thru "35699" (100 combinations) or "356 A/B/D 0 thru 9" (30 combinations) or "356 0 thru 9A/B/D" (30 combinations). There are 160 total combinations. You must wait 5 seconds between entering these combinations. After you finally locate the correct combination to unlock the Controller and place it into the programming mode write that number down on a peice of paper, and/or reprogram the access code back to the Default No.35687 so you don't have to go thru the whole process again if you lose or forget the code." Hope this helps someone else out there who has a CSI controller collecting dust because they can't reprogram it. 73 Doug N3DAB http://www.repeater-builder.com/other-mfrs/csi-32.pdf ________________________________________________________________________ Check Out the new free AIM(R) Mail -- 2 GB of storage and industry-leading spam and email virus protection.
