B.1.3 GS2200M UART Connector Pinouts
The UART peripheral connector (J6) is a Pmod™ Type 4-compatible interface. It supports
attaching a peripheral or a host device via a UART interface. Either UART0 or UART1 in
the GS2200M may be routed to the connector, as configured via jumper settings on header
J18.
- UART0 routed to USB port / UART1 routed to peripheral connectors for host mode
- UART0 routed to USB port / UART1 routed to peripheral connectors for peripheral mode
- UART0 routed to peripheral connectors for peripheral mode / UART1 routed to USB port
Alternatively, either UART can be left unconnected by omitting jumpers for that port.
The USB port is always configured for peripheral mode such that the board will always be
a peripheral to the host PC it is connected to.
