 ===== Jumpers =====
   * For the CAN bus, we use the built in 120Ω terminal resistor, activated by bridging jumper JP3.
-  * For the RS-485, we use the built in bias network of resistors, activated by bridging jumpers JP1, JP2 and JP4. //TODO, check this//

-===== Watchdog =====
+===== Logic Controller Configuration =====
-The watchdog of the Strato Pi has to be configured for our use. First the firmware has to be updated to 3.5. Then we can connect to the serial interface.
+Configuration of the StratoPi logic controller is performed through a 1200 baud, 8N1 UART connection at the following pins (5V if board is not connected to RPI)
-^ Heading 1      ^ Heading 2       ^ Heading 3          ^
+^ USBUART      ^ Stratopi       ^ Corresponding pin on RPI          ^
-| Row 1 Col 1    | Row 1 Col 2     | Row 1 Col 3        |
+| GND    | 6     | GND        |
-| Row 2 Col 1    | some colspan (note the double pipe) ||
+| 5V    | 2 | 5V |
-| Row 3 Col 1    | Row 3 Col 2     | Row 3 Col 3        |
+| RX    | 35     | GPIO19        |
+| TX    | 33     | GPIO13        |
+Pin counting begins with the pin closest to the screw terminals as 1.
-USBUART - Stratopi - Corresponding pin on RPI
+This configuration assumes FW 3.5 on the logic controller.
-GND - 6 - GND
-V - 2 - 5V
-RX - 35 - GPIO19
-TX - 33 - GPIO13
-Where counting begins with the pin closest to the screw terminals as 1
-baud, 8N1
+==== Watchdog ====
-We have FW3.1, deduced by XFW?(and others) not working
+  * ''XWED'' Set the watchdog enable mode to disabled (Badly named, in this mode, it's enabled by setting WatchdogEnable gpio pin from the RPI).
-Seems buggy, only responds if beginning with command "XSM?". Can then run command:
+  * ''XWH00005'' Set timeout to 5 sec.
-"XWH00005" to set timeout to 5 sec
+  * ''XWW00001'' Set the watchdog forced shutdown timeout to 1sec(min).
-"XCCS" to permanently save setting
+  * ''XCCS''  Make configuration permanent.
+==== RS-485 ====
+The StratoPi uses the PIC MCU to toggle between receiving and transmitting on the half-duplex RS-485 connection. selecting the toggleing configuration is supposed to happen automatically, but for 115200baud, this happens too slow in cases where the receiving and transmitting switches instantaneously, producing garbage data. An example of this is the command mode of the TB Live hydrophone used.
+To fix this, the [[https://www.sferalabs.cc/files/strato/doc/stratopi-logic-controller-advanced-configuration-guide.pdf|StratoPi logic controller]] must be configured sending these commands over the 1200 8N1 setup serial:
+  XSMF // Set TX-Enable fixed speed mode
+  XSP98N1 // Set 115200 baud, 8N1
+  XCCS // Make configuration permanent
