Interfacing the SX-560
Part Number 140-00192-100
OEM Interface
The OEM Interface (JP2) is the primary method for communications between the SX-560 and your
device. It is a 40-pin header that includes the necessary pins for serial data I/O, GPIO, and power.
Table 13 describes the OEM interface pinout for the SX-560 module.
