Connectors (male) of ESX-3XL (KS1 and KS2)
First of all, connectors are shown once again for a easier finding of pins.
Power connection wiring
Notes:
1. Minimal connections for operating are D+, +UE and GND.
2. Fuse is recommended if short circuit to UBat cannot be excluded.
Attention: Applying this fuse can result in minor precision of applied sensors!
3. +UB1 is needed when 4A-High side outputs are used.
4. +UB2 is needed when 2.5A-High side outputs 1 to 8 are used.
5. +UB3 is needed when 2.5A-High side outputs 9 to 16 are used.
Communication wiring
Notes:
1. Default CAN-Interface for KEFEX-Winflash is CAN1.
2. Standard mode for RS-232 is a three line serial connection (RxD, TxD, Gnd) with no handshake (neither hardware nor software).
3. Avoid short circuits on TxD-lines to GND or +UBat under all circumstances!!!

Description
1. Power ON LED: (green)
This LED indicates that all necessary voltages in the ESX-3XL for running the CPU are given. At least +UE and D+ have to be powered on for this.
If this LED doesn't light, the ESX-3XL has no supply or it is damaged.
2. ERROR LED: (red)
This LED shows severe errors which were encountered during POST (Power On Self Test) or while the system is/was running. The following table shows various blink codes for various errors:
| Blink code | Error name | Explanation of error |
|---|---|---|
| LED is off | No error | While there is no error the LED remains off |
| LED is always on | Flash ROM error | System encountered a flash ROM CRC error during booting up. System is halted. Please contact your local sales representative! |
| LED is continously fast flashing (5 Hz) | EEPROM error | System encountered a EEPROM read error during POST or a EEPROM write error during runtime. It is possible that this error can be fixed by using the function x_sys_config_supervisor. If the error persists please contact your local sales representative! |
| LED flashes 3x, then pausing for app. 300ms | UF error | System encountered a low voltage power supply (< 8 V) error during runtime. This error is non-permanent. |
| LED flashes 2x, then pausing for app. 500ms | Usys error | System encountered an error on the system voltages during runtime. This error can be seen for a short time during power up and is non permanent. |
| LED flashes 1x, then pausing for app. 700ms | Watchdog error | System encountered an watchdog error. The watchdog wasn't retriggered in time. |
3. User LED 1: (red/green)
This LED is freely programmable by the user. Look at x_sys_set_led.
4. User LED 2: (red/green)
This LED is freely programmable by the user. Look at x_sys_set_led.

For test of the Engine RPM, Output Switches, CVT and Steering modules something like the following hardware will be needed.
IO for ECS
Inputs:
Channel 1 (KS1 pin 70) : Extra engine speed input. (PNP 12 V). Channel 2 (KS1 pin 12) : Extra prop shaft (CVT) input. (PNP 12 V). Channel 5 (KS1 pin 69) : Prop shaft (CVT) quadrature encoder A. (PNP 12 V). Channel 6 (KS1 pin 11) : Prop shaft (CVT) quadrature encoder B. (PNP 12 V). Channel 7 (KS1 pin 30) : Engine speed. (PNP 12 V). ??Channel 8 (KS1 pin 49) : CVT Neutral. Switch to 12 V (i.e. PNP type). Channel 9 (KS1 pin 68) : Steering angle left. (Potentiometer). Channel 10 (KS1 pin 10) : Steering angle right. (Potentiometer).
Outputs:
Channel 2 (KS1 pin 33) : Aux Rear (hydraulics). Channel 3 (KS1 pin 51) : Lights (head). Channel 4 (KS1 pin 52) : Horn. Channel 6 (KS1 pin 14) : Reversing Lights. Channel 7 (KS1 pin 71) : Flashing Light Left (indicator light). Channel 8 (KS1 pin 72) : Flashing Light Right (indicator light). Channel 9 (KS2 pin 49) : Steering reference. Channel 13 (KS2 pin 50) : CVT Speed reference. Channel 16 (KS2 pin 70) : PTO Rear. Channel 17 (KS2 pin 51) : Engine speed reference.
Sensor supply.
Uext1 (KS1 pin 66) ??Supply for steering angle potentiometers? AGND (for Uext1) (KS1 pin 47)
Supply for output groups.
+UB1 (KS1 pin 5) +UB2 (KS2 pin 5) +UB3 (KS2 pin 2)
RS-232
TXD (KS1 pin 44) RXD (KS1 pin 63)
CAN1 (interface to NavCom).
CAN1_H (KS1 pin 7 / 8) CAN1_L (KS1 pin 26 / 27) Consider whether both pins should be connected (what would be the easiest in case the test pattern generator CAN2 should be connected/disconnected).
CAN2 (generating test pattern (commands)).
CAN2_H (KS1 pin 45 or 46) CAN2_L (KS1 pin 64 or 65) Idea: write task which will output a test pattern - not necessarily listening to any reports. If complicated tests (many packets) are needed it seems the generation of CAN messages should be automated - the ESX 3XL seems to be the only available device which can generate CAN message patterns).
Supply for computer.
GND (KS1 pin 2) +UE (KS1 pin 6) D+ (KS1 pin 25) ??Will this be necessary for this test?
??Consider sequencing input for test purposes? The RS-232 or the CAN bus should probably be used instead.
