Monitoring Module Status
You can monitor the module status using the yellow, green and orange LED status indicators on the
Evaluation Daughtercard. Table 2 defines the default functions of the LED status indicators.

OEM Interface
The OEM interface is a 40-pin header (JP2) that is used to connect the SX-560 module to the SX-560-6900
Evaluation Daughtercard. It will also serve as the primary means of communications between the SX-560 and
your OEM device (refer to Chapter 5 for information on using this header to connect with your device).
Table 3 shows the OEM interface pinout for the Evaluation Daughtercard. Table 4 shows the OEM
interface signal descriptions. Please note that the OEM interface signals are not directly accessible from
the OEM header when the Evaluation Daughtercard is used. Rather, these signals are available through
convenient connectors on the Evaluation Daughtercard, such as the 26-pin I/O Header and the 9-pin
serial connectors. These connectors are described later in this chapter.
All input and output signals, except the differential signals, are 0 to 3.3 V logic signals.
