2.2 Hardware Connections
2.2.1 Attach Module to Prototyping Board
Turn the RCM3000 module so that the Ethernet connector end of the module extends off
the Prototyping Board, as shown in Figure 1 below. Align the pins from headers J1 and J2
on the bottom side of the module into header sockets RCM2JA and RCM2JB on the Proto-
typing Board (these sockets were labeled J12 and J13 on earlier versions of the Prototyping
Board).

Figure 1. Install the RCM3000 Module on the Prototyping Board
Although you can install a single module into either the MASTER or the SLAVE position
on the Prototyping Board, all the Prototyping Board features (switches, LEDs, serial port
drivers, etc.) are connected to the MASTER position — install a single module in the
MASTER position.
NOTE: It is important that you line up the pins on headers J1 and J2 of the RCM3000
module exactly with the corresponding pins of sockets RCM2JA and RCM2JB on the
Prototyping Board. The header pins may become bent or damaged if the pin alignment
is offset, 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 header sockets—press down in
the area above the header pins using your thumbs or fingers over the connectors as shown
in Figure 1. Do not press down on the middle of the RCM3000 module to avoid flexing
the module, which could damage the module or the components on the module.
Should you need to remove the RCM3000 module, grasp it with your fingers along the sides
by the connectors and gently work the module up to pull the pins away from the sockets
where they are installed. Do not remove the module by grasping it at the top and bottom.
