How to determine the MAC address of a SiteWorx Gateway (DLGW3)

Updated by Dan Buckley

The MAC address of a DLGW3 is based on the serial number. There are three serial number ranges and each serial number range has a different MAC address range:

  • 02020100 to 02020FFF use 7C70BC202000 to 7C70BC202EFF
  • 02021000 to 02021FFF use 7C70BC203000 to 7C70BC203FFF
  • 02022000 to 02022FFF use 7C70BC204000 to 7C70BC204FFF

Serial Numbers 02020100 to 02020FFF

GW3 MAC address format is 7C:70:BC:20:2x:xx where xxx is the last 1.5 bytes of the serial number minus 100.

Examples:

SN 02020123 has MAC of 7C:70:BC:20:20:23.

SN 02020709 has a MAC of 7C:70:BC:20:26:09

Serial Numbers 02021000 to 02021FFF

The MAC addresses begin in 7C:70:BC:20:3x:xx and the XXX is a direct match, do not subtract 0x100 for 02021XXX serials

Example:

0202103c is 7C:70:BC:20:30:3c

Serial Numbers 02022000 to 02022FFF

The MAC addresses begin in 7C:70:BC:20:4x:xx and the XXX is a direct match.

Example:

0202203c is 7C:70:BC:20:40:3c
