Console Port Connection

Connecting an Open-Ended Cable to the Console Port

The R2 console port requires that the cable is connected to another device; otherwise,
spurious noise could cause the R2 console port to be unresponsive especially when the R2
is reset. If you plan to connect a cable to the console port but not always have that cable
connected to a device (such as connecting the console cable to a patch panel), you need to
attach the TX and RX pins to ground, as shown in the cabling diagram below. A patch
panel would be between the two RJ45 connectors.
