Rule R704

R704 *Only use allowed ports and bandwidth to communicate with the ROBOT. Communication between the ROBOT and the OPERATOR CONSOLE may not exceed the following and is restricted to network ports listed in Table 8‑5:

A. 7 Mbits/second for Vivid Hosting wireless bridge radios

B. 4 Mbits/second for OpenMesh radios

Table 8‑5 Open FMS ports

Port	Designation	Bi-directional?
UDP/TCP 1180-1190	Camera data from the roboRIO to dashboard software when the camera is connected the roboRIO via USB	Yes
TCP 1735	SmartDashboard	Yes
UDP 1130	Dashboard-to-ROBOT control data	Yes
UDP 1140	ROBOT-to-Dashboard status data	Yes
HTTP 80	Camera connected via switch on the ROBOT	Yes
HTTP 443	Camera connected via switch on the ROBOT	Yes
UDP/TCP 554	Real-Time Streaming Protocol for h.264 camera streaming	Yes
UDP/TCP 1250	CTRE Diagnostics Server	Yes
UDP/TCP 5800-5810	Team use	Yes

Teams may use these ports as they wish if they do not employ them as outlined above (i.e. TCP 1180 can be used to pass data back and forth between the ROBOT and the Driver Station Software if the team chooses not to use the camera on USB).

Note that the 4 Mbit limit will be strictly enforced by the wireless bridge.

The FMS Whitepaper has more details on how to check and optimize bandwidth usage.

While FIRST makes every effort to provide a wireless environment that allows teams access to a full 4 Mbits/second data rate (with about 100 Kbit used for ROBOT control and status), at some events wireless conditions may not accommodate this.
