Functional DIP Switches
DIP-Switch settings for interfaces like JTAG, RS485 and CAN.
CAN1 (X5)
DIP switch S3 is used to configure the CAN interface CAN1.
Both switches must be set to ON or OFF otherwise the CAN Bus has an improper termination.
| DIP | S3-1 & S3-2 |
|---|---|
| ON | CAN Bus not terminated |
| OFF (default) | CAN Bus terminated (120Ω) |
CAN2 (X6)
DIP switch S7 is used to configure the CAN interface CAN2.
Both switches must be set to ON or OFF otherwise the CAN Bus has an improper termination.
| DIP | S7-1 & S7-2 |
|---|---|
| ON | CAN Bus not terminated |
| OFF (default) | CAN Bus terminated (120Ω) |
RS485 configuration (S5)
DIP switch S5 is used to configure the RS485 interface.
| DIP | S5-1 | S5-2 |
|---|---|---|
| ON | RS485 TxD terminated (120Ω) | RS485 RxD terminated (120Ω) |
| OFF (default) | RS485 TxD not terminated | RS485 RxD not terminated |
JTAG configuration (S13)
DIP switch S13 is used to configure the JTAG interface.
| DIP | S13 |
|---|---|
| ON | JTAG via connector X11 |
| OFF | JTAG via Micro-USB (x10) |
