User’s Manual 3
Table 1 summarizes the main features of the RCM3209 and the RCM3229 modules.
The RCM3209 and RCM3229 are programmed over a standard PC USB serial port
through a programming cable supplied with the Development Kit, and can also be pro-
gramed directly over an Ethernet link using the RabbitLink.
Appendix A provides detailed specifications for the RCM3209/RCM3229.
1.2 Comparing the RCM3209/RCM3229 and RCM3200/RCM3220
This section compares the two lines of RabbitCore modules.
• Temperature Specifications
— We can no longer obtain certain components for the
RCM3200/RCM3220 RabbitCore modules that support the -40°C to +70°C temperature
range. RCM3200/RCM3220 RabbitCore modules manufactured after May, 2008, are
specified to operate at 0°C to +70°C. The RCM3209/RCM3229, rated for -40°C to
+85°C, are offered to customers requiring a larger temperature range after May, 2008.
•
Maximum Current — The RCM3200/RCM3220 draws 255 mA vs. the 325 mA
required by the RCM3209 (with Ethernet) or 190 mA (RCM3229 without Ethernet).
• LEDs
— The
LNK
/
ACT
LEDs have been combined to one LED on the RCM3209, and
the RCM3209 has an
FDX
/
COL
LED where the
ACT
LED was on the
R
CM3200. The
RCM3229, like the RCM3220, has no LEDs and no Ethernet.
•
Ethernet chip. A different Ethernet controller chip is used on the RCM3209. The
Ethernet chip is able to detect automatically whether a crossover cable or a straight-
through cable is being used in a particular setup, and will configure the signals on the
Ethernet jack interface. The RCM3229, like the RCM3220, has no Ethernet interface.
• Dynamic C
— You may run an application developed for the RCM3200/RCM3220 on
the RCM3209/RCM3229 after you recompile it using Dynamic C v. 9.60. The new
Dynamic C release incorporates many of the modules that previously had to be pur-
chased separately.
