    XStream‐PKG‐R™ RS‐232/422/485 RF Modem User’s Guide  3.2.3. Receive Mode If a modem detects RF data while operating in Idle Mode, the modem transitions into Receive Mode to start receiving RF packets. Figure 3.7. Reception of RF Data    After a packet is received, the modem checks the CRC (cyclic redundancy check) to ensure that the data was transmitted without error.

In order to achieve this state, DI3 (SLEEP) pin must be asserted (high). The modem remains in Pin Sleep until the DI3 pin is de-asserted. After enabling Pin Sleep, the SLEEP pin controls whether the XStream Modem is active or in Sleep Mode.
