Revision to Connecting an LCD control panel

Ian A-S

== Connecting a PanelDue ==
-There are two cable options for connecting the PanelDue, both options are included with the PanelDue kit. Option 1 is the included 10-wire ribbon cable. Option 2 is the included 4-wire cable with Molex KK connector ends.
+There are two cable options for connecting the PanelDue, both options are included with the PanelDue V3 kit. Option 1 is the included 10-wire ribbon cable. Option 2 is the included 4-wire cable with Molex KK connector ends. For some boards, both cables need to be plugged in to enable both TFT panel and SD card socket.
-=== PanelDue version 3.0, and Duet 2 (WiFi/Ethernet) revision 1.01 or later ===
+Information for connecting older versions of the PanelDue is available here: [https://miscsolutions.wordpress.com/paneldue/]
-==== Option 1: Ribbon cable ====
+=== PanelDue 3 connection matrix ===
-In order to use the SD card slot on the PanelDue, you must use the ribbon cable option. If you do not wish to use the SD card slot, it's recommended to use the 4-wire cable option described in option2.

-Connect a 10-way ribbon cable between socket X5 on the PanelDue and socket CONN_SD on the Duet 2. The connector is a standard 10 pin 2 row 2.54mm pitch box connector that accepts IDC connectors for 1.27mm ribbon cable.
+== Option 1: Ribbon cable ==
+
+* Available on PanelDue V2.0 and V3.0 only
+* Compatible with Duet 2 WiFi, Ethernet, Maestro
+* Supports use of PanelDue SD card slot
+* Connects to CONN_SD on Duet 2
+* Limit cable length to 400mm for reliability
+* For PanelDue V2.0, both the ribbon cable '''AND''' 4-wire cable need to be connected to enable use of SD card slot.

+In order to use the SD card slot on the PanelDue, you must use the ribbon cable option. If you do not wish to use the SD card slot, it's recommended to use the 4-wire cable option described in option 2.

In tests using standard 28awg 1.27mm spaced ribbon cable, 400mm worked reliably but 800mm did not. So 400mm is the maximum recommended cable length. You can also get 26awg 1.27mm ribbon cable, and by using such cable you may be able to achieve reliable operation with cables longer than 400mm.
-Caution: if you are using a thermocouple and/or PT100 daughter board, the use of long ribbon cables between the Duet and PanelDue may affect communication between the Duet and the daughter boards, because the ribbon cable connection to the SD card on PanelDue uses the same SPI bus as the daughter boards.

+== Option 2: 4-way cable ==
-Use' a 4-way cable terminated in Molex KK or compatible connectors as shown here:
+* Compatible with all Duets and all PanelDues
+* Provides longest cable run
+* SD socket on PanelDue not accessible; use ribbon cable or see notes for SD connectivity

The length of the 4-way cable is not critical, however the resistance per conductor should not exceed 0.1 ohm. The SD card socket on the TFT panel will not be functional. The cables supplied by Escher3D and Duet3D are about 800mm long. There have been reports of cables up to 1500mm long being successfully used. Take care to route the cable away from motor and endstop cables. Twisting the cables may help prevent cross talk interference.
-=== PanelDue versions 1.0,1.1. or 2.0 and/or Duet 2 WiFi revision 1.0 or Duet 0.8.5 ===
+== Notes ==
-Use the 4-way cable as described above. If you are using PanelDue 2.0 or 3.0 with Duet 2 (WiFi/Ethernet) then you can optionally connect the ribbon cable as well in order to use the SD card socket on the TFT panel.
+=== Duet 3 ===
+
+[image|1876|align=right]
+
+A PanelDue can be connected to connector IO_0 using a 4-core cable wired like this. Note that while the PanelDue can be connected while a Single Board Computer is attached to control the Duet, the PanelDue will not be fully functional (file operations do not work correctly as of RRF 3.0). PanelDue is fully functional (except SD card socket) in Duet 3 stand-alone mode.
+
+=== Duet 2 WiFi v1.0 and v1.01 ===
+
+Older versions of the Duet 2 WiFi/Ethernet need both the 4-wire and ribbon cable to be plugged in to use the TFT Panel and the SD card socket, when connecting PanelDue v2.0 or v3.0.
=== Duet 0.6 ===
