2.2 Hardware Connections
There are three steps to connecting the Prototyping Board for use with Dynamic C and the
sample programs:
1. Attach the RCM3700 module to the Prototyping Board.
2. Connect the programming cable between the RCM3700 and the COM port on the
workstation PC.
3. Connect the power supply to the Prototyping Board.
The connections are shown for the RCM3700 Prototyping Board, and are similar for the
RCM3720 Prototyping Board.
2.2.1 Step 1 — Attach Module to Prototyping Board
Turn the RCM3700 module so that the Ethernet jack is on the left as shown in Figure 2
below. Insert the module's J1 header into the TCM_SMT_SOCKET socket on the Proto-
typing Board. The shaded corner notch at the bottom right corner of the RCM3700 module
should face the same direction as the corresponding notch below it on the Prototyping
Board.

NOTE: It is important that you line up the pins on header J1 of the RCM3700 module
exactly with the corresponding pins of the TCM_SMT_SOCKET socket on the Proto-
typing Board. The header pins may become bent or damaged if the pin alignment is off-
set, and the module will not work. Permanent electrical damage to the module may also
result if a misaligned module is powered up.
Press the module's pins firmly into the Prototyping Board headers.
