DSC keyfob 5 digit serial number

If you left mouse click the 5, a check the box will appear. You check it off, and it will switch from 5 digit to 6 digit ESN.

If the 5010 programming does not support 6 digit ESN at all, you will have to call DSC support to get the correct conversion.

The 5 or 6 field is greyed out and I can't alter that field in the DLS software. I suspect because the download software knows that it's connected to a PC5010 version 1.0 and the "Note" under that field says

5-digit serial numbers must be used if this module is used with PC5010 V1.0

I wonder whether DSC has some conversion from a 6-digit ESN to 5- digit? Or am I stuck unless I find an older fob that lists both 6- digit and 5-digit ESNs?

This is the conversion they do

1. The 1st digit of ESN number is also 1st digit of SN
2. Open up calculator in Microsoft Windows
3. Click on VIEW at top of calculator and select SCIENTIFIC

3a. Click on HEX button at top left of calculator

1. Input the 2nd, 3rd and 4th characters or numbers of the ESN number
2. Click on DEC button at top left of calculator
3. These are the last 4 digits of the SN number Example: ESN 26DA4A would be SN 21754

1. The 1st digit of ESN number is also 1st digit of SN
2. Open up calculator in Microsoft Windows
3. Click on VIEW at top of calculator and select SCIENTIFIC (or PROGRAMMING in Vista or Win 7)

3a. Click on HEX button at top left of calculator

1. Input the 2nd, 3rd and 4th characters or numbers of the ESN number
2. Click on DEC button at top left of calculator
3. These are the last 4 digits of the SN number Example: ESN 26DA4A would be SN 21754

Awesome!!! It's too late for me to download the panel and test it, but that looks to be the solution as the DLS software accepts the converted 5-digit ESN

Thanks a bunch!!!

I forgot to post the rest of it, here's the entire process

1. The 1st digit of ESN number is also 1st digit of SN 2. Open up calculator in Microsoft Windows 3. Click on VIEW at top of calculator and select SCIENTIFIC 4. Click on HEX button at top left of calculator 5. Input the 2nd, 3rd and 4th characters or numbers of the ESN number 6. Click on DEC button at top left of calculator 7. These are the last 4 digits of the SN number Example: ESN 26DA4A would be SN 21754
2. If 0 is 2nd digit use 3rd and 4th digits into calculator then add

00 to beginning of the result Example: If ESN is 6039E9 1. The 1st digit (6) of ESN number is also 1st digit of SN 2. Click on VIEW at top of calculator and select SCIENTIFIC 3. Click on HEX button at top left of calculator 4. Enter 3rd and 4th digit (39) 5. Click DEC button, the result should be 57 6. The SN number will be 60057

You are almost better off with a v2 or higher 5010, that v1 was odd in how it handled hardwire and wireless sensors.

And someone said Napco software is a pain???

No, DSC's software has a simple check box to toggle 5 or 6-digit serial numbers in fact it's amazing he missed it. The calculation I posted has nothing to do with the software other than determining the converted serial number to use modern sensors on ancient and rare PC5010 v1.0 or WS5010 panels.

Napco's software on the other hand is bloated, slow and has a terrible interface regardless of the wireless sensors and panels it is programming.

I tried toggling the 5 digits to 6 even before my first post but it's not an option. I suspect DSC software is smart enough to know what number of digits is required based on the panel that it's connected to. Despite a fiddly conversion, the fact that my customer can purchase a current wireless receiver and fob that works on a panel that is 14 years old is remarkable.

It was a good panel but v2 really made it a classic
