TS-7250-V3 TS-SER4

TS-SER4

Product Page
8-bit IO

The TS-SER4 supports 4 UARTs as RS-232, RS-485, or RS-422.

Refer to the TS-SER4 manual for hardware documentation.

The TS-SER4 implements 16550A based UARTs which require a kernel driver.

Under Linux this requires a device tree change. See the Kernel compile section for more details about getting set up the compile the kernel.

For example, with the IRQ2,IRQ6, and COM1 jumpers installed.
