TS-8820-jumpers
From embeddedTS Manuals
The TS-8820 has two sets of jumpers, one located near the System-on-Module (inside the enclosure), and another near the system power, red, and green LEDs. These jumpers control a number of aspects of the platform's behavior. The jumpers are labeled on the silkscreen rather than numbered:
| Label | Description |
|---|---|
| Force SD Boot | When jumper is set, boot kernel and Debian from the SD card. Otherwise boot kernel and Debian from eMMC. |
| U_Boot | When jumper is set, U-Boot attempts to boot from USB before dropping to a U-Boot shell. Otherwise boot straight to Debian. |
| No Chrg | When jumper is set, disable charging of the TS-SILO Supercapacitors. Beneficial for early development and testing. |
| Term. CAN | When jumper is set, adds a 124 ohm termination resistor across the isolated CAN H and L pins. |
| Term. 485 | When jumper is set, adds a 124 ohm termination resistor across the isolated TS-485 + and - pins. |
