Figure 1 SX-550-1701 (left) and SX-550-2701 (right)
The SX-550-1701 and SX-550-2701 are virtually identical in form and functional identical, with a
few minor differences. The one major difference is the SX-550-2701 includes FCC modular
approval (see Appendix D). Other differences include:
• International roaming (802.11d) is a standard non-configurable feature of the SX-550-
2701, so there are no corresponding configuration items.
• Programmable RTS threshold is supported on the SX-550-1701 and not on the SX-550-
2701
• User defined scan mask is supported on the SX-550-2701 and not on the SX-550-1701
• User defined transmit power level supported on the SX-550-2701 and not on the SX-550-
1701
• 802.11b only mode supported on the SX-550-1701 and not on the SX-550-2701
• Default radio mode is 802.11b/g on the SX-550-1701 and 802.11a/b/g on the SX-550-
2701
• Transmit rate setting supported on the SX-550-1701 and not on the SX-550-2701
• AP density (roaming control) supported on the SX-550-1701 and not on the SX-550-2701
• WPA group key for link encryption supported on the SX-550-1701 and not on the SX-
550-2701
• Blank SSID indicating any SSID OK supported on the SX-550-1701 and not on the SX-
550-2701
To expedite the development process, the SX-550-6900 Evaluation Daughtercard is available.
This board includes an RJ45 Ethernet connector, two 9-pin serial connectors, power supply,
antenna, cables, and software. The Evaluation Daughtercard is described in detail in Chapter 2
of this manual.
