The SX-550 embedded intelligent module provides a complete solution for integrating wireless or
wired networking technology into virtually any OEM product that has an RS-232 or UART serial
port. It can also be used as an Ethernet to 802.11 bridge to enable wireless capabilities on
devices that have an Ethernet interface. It is available in two models:
Part Number 40183-101
IMPORTANT: The SX-550-2701 modular approval requires use of an antenna and antenna cable with
the same characteristics as those used for the Silex testing. Silex can only support testing of other
antenna configurations in the end user product for the US and Canada regulatory domains.
Important: The SX-550-1701 model does NOT include FCC Modular Approval, so it is the responsibility of the
OEM to test for compliance with FCC Part 15 Subparts C and E and RSS-210 intentional radiation standards.
SX-550-0700 Ethernet model. The SX-550 Ethernet model consists of a printed circuit
board (processor card) that measures 44.60 mm by 59.70 mm. It includes an embedded
processor, auto-sensing 10Base-T/100Base-TX Ethernet MAC/PHY, two UART serial
ports (one port is dedicated for use with a console terminal), intelligent power control, and
an embedded operating system with a full networking stack and drivers.
SX-550-2701 WLAN model. This wireless model uses the same processor card as the
Ethernet model, but also adds a second printed circuit board (radio card) that contains an
802.11a/b/g wireless LAN radio based on Atheros’s AR5413 chipset. This second board
measures 36.0 by 59.70 mm; the two boards plug together via a 20-pin connector. Note
that the Ethernet interface and the wireless radio cannot be used concurrently except
when the Ethernet-to-802.11 bridge mode feature is enabled. The SX-550-2701 includes
FCC Modular Approval, which can eliminate the need to test for compliance with FCC
Part 15 Subparts C and E and RSS-210 intentional radiation standards. Please refer to
Appendix D for specific information about FCC Modular Approval.
SX-550-1701 WLAN model. This wireless model uses the same processor card as the
Ethernet model, but adds a second printed circuit board (radio card) that contains an
802.11a/b/g wireless LAN radio based on Conexant’s PRISM WorldRadio chipset. This
second board also measures 44.60 by 59.70 mm; the two boards plug together via a 20-
pin connector. Note that the Ethernet interface and the wireless radio cannot be used
concurrently except when the Ethernet-to-802.11 bridge mode feature is enabled.
