RabbitCore RCM3200
1.2 Comparing the RCM3209/RCM3229 and RCM3200/RCM3220
We can no longer obtain certain components for the RCM3200/RCM3220 RabbitCore
modules that support the originally specified -40°C to +70°C temperature range. Instead of
changing the design of the RCM3200/RCM3220 RabbitCore modules to handle available
components specified for the original temperature range, we decided to develop a new
product line — the RCM3209/RCM3229 — based on the RCM3900 RabbitCore modules
that were released for the same reason.
The RCM3209/RCM3229 modules are similar in form, dimensions, and function to the
RCM3200/RCM3220 modules. We strongly recommend that existing RCM3200/RCM3220
customers and designers of new systems consider using the new RCM3209/RCM3229
RabbitCore modules.
This section compares the two lines of RabbitCore modules.
Temperature Specifications
— RCM3200/RCM3220 RabbitCore modules manufac-
tured 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 RCM3200. 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 or later. The
new Dynamic C release incorporates many of the modules that previously had to be
purchased separately.
