John, there is a manual on line at the Repeater-Builder site, but your unit may be an earlier version of the EPROM than the one documented in that manual.
The default decode sequence is 12345# if it is in the factory original state. I had several that were not, and found that I could remove the RAM chip from the Dallas Semiconductor battery back up for a few minutes and have the processor come back up in the defauld condition when it was replaced and could program from there. You have to put the processor back into the RS-232 access mode after this step, and you have to have a special cable (not standard RS-232) in order to program it via computer. The cable is documented in the manual and you will find that older units will operate a sub-set of the commands shown in the manual. 73 - Jim W5ZIT -----Original Message----- From: Maire-Radios <[EMAIL PROTECTED]> To: Repeater-Builder@yahoogroups.com Sent: Sat, 14 Jul 2007 11:59 am Subject: [Repeater-Builder] Zetron can any tell me the default program codes for the: Zetron model 38 and Zetron model 38A thank you, John ________________________________________________________________________ Check Out the new free AIM(R) Mail -- Unlimited storage and industry-leading spam and email virus protection. =0
