Serial Ports
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
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.

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 release incorporates many of the modules that previously had to be pur-
chased separately.
