2.2.2.1 RS-232 Connectivity (X5)
Figure 8: RS-232 Interface Connector X5
Two RS-232 transceivers on the phyBOARD-Regor convert the TTL level signals of UART0
(the standard console) and UART2 from the phyCORE-AM335x to RS-232 level signals. The
RS-232 level signals are available at the Phoenix Contact MINI COMBICON connector X5
(5 positions, 3.5 mm pitch).
Connector X5 is located on the right side of the board (
Figure 2
).
Figure 8
shows a detailed
view of the X5 connector.
Table 8
shows the pin assignment of X5. The pin-description in
the table is given from the perspective of the phyBOARD-Regor.
The UART0 interface serves as the standard console output of the phyCORE-AM335x module
on the phyBOARD-Regor. The initial setting of the UART0 interface is specified to a baud-
rate of 115200 baud with 8N1 configuration (8 data bits, no parity bit, 1 stop bit).
Pin Signal Description
1 UART0_RXD_RS232
UART0 serial receive signal RS-232 level (receive signal from
peripheral device at phyBOARD-Regor)
2 UART0_TXD_RS232
UART0 serial transmit signal RS-232 level (send signal to
peripheral device from phyBOARD-Regor)
3 GND Ground
4 UART2_RXD_RS232
UART2 serial receive signal RS-232 level (receive signal from
peripheral device at phyBOARD-Regor)
5 UART2_TXD_RS232
UART2 serial transmit signal RS-232 level (send signal to
peripheral device from phyBOARD-Regor)
