Overview

The Digi 76002109 is an Ethernet adapter cable for rail installations, terminated with a 4-pin M12 D-code female connector on one end and an 8-pin M12 X-code male on the other. It lets the M12 D-code Ethernet cabling installed for a Digi WR44 RR plug straight into the X-code ports on a TX64 5G Rail router - so a router upgrade does not force a re-cabling of the vehicle.

  • Adapts M12 D-code Ethernet cabling to M12 X-code router ports
  • 4-pin M12 D-code female connector on the harness end
  • 8-pin M12 X-code male connector on the router end
  • Specified for Digi TX64 5G Rail and WR44 RR installations
  • Locking threaded M12 couplings on both ends resist vibration
  • Green jacket follows Ethernet color convention in vehicle looms
  • Digi part number 76002109
  • Upgrade WR44 RR sites to the TX64 5G Rail without re-cabling the vehicle

The expensive part of upgrading a rail router is rarely the router - it is touching the cabling that was certified and dressed into the vehicle years ago. Digi's 76002109 exists so you do not have to. It adapts the M12 D-code Ethernet cabling used with the WR44 RR to the M12 X-code Ethernet ports on the TX64 5G Rail, one green adapter cable per Ethernet run.

Both ends are locking M12 connectors, the rail-standard format whose threaded coupling shrugs off the vibration that destroys RJ45 latches in vehicles. The D-code female end accepts the existing 4-pin D-code male harness lead; the X-code male end plugs into the TX64 Rail's 8-pin Ethernet socket. Keyed codings mean neither end can be forced onto the wrong port type.

One engineering note worth knowing up front: D-code carries Fast Ethernet on four conductors, so a link adapted through this cable runs at 10/100 Mbps - exactly what the legacy WR44 RR cabling delivered. For most onboard systems that is ample, and it preserves the option of pulling X-code cabling later for gigabit without blocking today's migration.

Cloud Care Networks stocks the 76002109 alongside TX64 Rail routers and their power and antenna accessories, so fleet upgrades can be kitted on a single order with a spare adapter for the maintenance shelf.

Ideal for

  • Migrating WR44 RR rail installations to the TX64 5G Rail router
  • Connecting legacy D-code Ethernet harnesses to X-code equipment
  • Rolling-stock refits that must preserve certified cabling
  • Bench validation of rail router upgrades before fleet rollout

Questions buyers ask

What is this adapter cable for?

It joins M12 D-code Ethernet cabling - the type installed for Digi WR44 RR rail routers - to the M12 X-code Ethernet ports on the Digi TX64 5G Rail. It is the standard migration piece when upgrading the router without re-cabling the vehicle.

Will the link run at gigabit speed through this cable?

No. M12 D-code carries Fast Ethernet over 4 pins, so the adapted link runs at 10/100 Mbps - the same rate the legacy cabling always supported. For gigabit you would pull X-code cabling end to end.

Which end goes where?

The 4-pin D-code female end accepts the existing harness's D-code male lead; the 8-pin X-code male end plugs into the TX64 Rail's Ethernet port and threads down to lock.

What is in the box?

One green Digi 76002109 adapter cable with factory-fitted M12 D-code female and M12 X-code male connectors.
