2.2.2.2 RS-485 Connectivity (X3)
Figure 9: RS-485 Interface Connector X3
An RS-485 transceiver on the phyBOARD-Regor converts the TTL level signals of UART1
from the phyCORE-AM335x to RS-485 level signals. The RS-485 level signals are available
at the Phoenix Contact MINI COMBICON connector X3 (5 positions, 3.5 mm pitch).
Connector X3 is located on the right side of the board (
Figure 2
).
Figure 9
shows a detailed
view of the X3 connector.
Table 9
shows the pin assignment of X3.
In case jumpers J5 and J6 (
section 2.1.4
) are set to the respective positions, the RS-485
level signals are also available at the card edge connector X7 (
section 2.2.8
).
