15.4 Baud Rate<br />
Baud Rate is set by either hardware or software configuration to 125kbps, 250kbps or 500Kbps. The<br />
baud rate will be set by software when DIP switch positions 7 and 8 are ON. For more information refer<br />
to Section 3.10.3—Baud Rate and Table 3.3—Baud Rate Switch Settings. The factory set baud rate is<br />
500Kbps.<br />
15.5 Calculating F/T Values for CAN<br />
The Net F/T multiplies each force and torque value with a factor before it is sent over the CAN interface.<br />
This allows for sending force and torque values with the full resolution. The application program has to<br />
divide each force and torque value with a specific factor to obtain the real data.<br />
Refer to Table 14.1—DeviceNet Input Bitmap for 16-bit data handling and Table 14.2—EtherNet/IP<br />
Input Bitmap for 32-bit data handling.<br />
