1.3 HLS Configuration using HUBs
Adding HUBs to the HLS network, the user system can satisfy it’s own needs (1) to (3) described above.
When adding a HUB to the network, the center IC constituting the HLS must be compatible
with the HUB. If incompatible, the center IC does not link correctly with satellite ICs.
1.3.1 Extending Total Length of Network Cable
Adding HUB(s) to the HLS network, the user can extend the total length of the network cable. Figure 1.2
shows an example of extending the total length of the network cable. Rt in the figure indicates a termination
resistor.
The user system can extend the recommended network cable length by adding the inserted count of HUBs
+1 to the basic HLS configuration. For example, adding a single HUB doubles cable length, adding two
HUBs triples cable length, and adding seven HUBs increases the cable length eightfold. Table 1-1 shows
the baud rates and the recommended total extension based on the number of the inserted HUBs when using
the recommended network connection.
