3.1. Driving Capability

Before introducing the driving capability of the I-2533CS-FD, some characteristics
of copper cable must be assumed. The AC parameters are 120Ω impedance and 5ms/,
line delay, and the DC parameter follows the table show below.
Table 3-1-1 Recommended DC parameter for CAN Bus Line
Wire Cross-Section [mm
Under the condition described above, users can refer to the following table to know
the maximum node number in each segment following ISO 11898-2 and the maximum
segment length when using different type of wire.
