A Digital Dash for Your Link G4+, the RDM-7

Running a Link G4+? The RDM-7 is a 7-inch CAN digital dashboard with a built-in Link G4+ preset. Pick Link in the setup wizard and the channels come up named and scaled, read straight off the bus. No tuning software, no licence, no subscription.

Which cable you need, and it depends on your ECU

There is no RDM adaptor loom for Link. Link make their own CAN cables, we stock them, and the right one is decided by whether your ECU is a plug-in or a wire-in.

  • Plug-in with the 5-pin CAN connector — the CANJST. This is the one most G4+ plug-ins take.
  • Wire-in with the 6-pin round connector on the front panel — G4+ Xtreme and Fury on CAN1, and G4+ Force and Thunder on CAN1. You want the CANLTW.
  • Wire-in taking CAN off the ECU header — G4+ Atom and Monsoon on CAN1; Storm, Xtreme and Fury on CAN2; Force and Thunder on CAN2. You want the CANSS.

All of them are 300 mm and terminate in Deutsch DTM-4, so they join straight onto the 2 m lead in the RDM-7 box. The CANEXT adds two metres if the run is longer, and the CANTEE splits the bus if you want a second CAN device on it.

If your ECU is a newer G4X plug-in with the 4-pin powered CAN connector rather than the 5-pin, you want the CANJST4 instead — that one is on the G4X page.

What the install takes

Four wires at the dash end: 12 V switched ignition, chassis ground, CAN High, CAN Low. Fuse the 12 V feed at 2 A. The plug is an eight-way push-in terminal block with release tabs — strip the wire, push it in, no crimping.

Link's CAN cables carry 12 V and ground alongside CAN High and CAN Low on the same DTM-4, pin 1 through pin 4.

What you get

800x480 IPS touchscreen, around 50 fps, under 20 ms from the bus to the screen. Up to 128 CAN channels. Onboard logging to microSD at 1 to 200 Hz in plain CSV. Thirteen widget types and as many layout presets as your card holds. The layout editor is served by the dash itself over Wi-Fi, so you build your screen in a browser tab on your phone.

Free firmware updates over Wi-Fi. No dealer visit and no licence.

Display, logging and CAN transmit only. The RDM-7 reads, displays, logs and transmits. It does not tune your ECU.
