You can use Table 28 as a reference while distinguishing or preparing the two kinds of Ethernet cables. While preparing the Ethernet cables, follow the chromatogram given in this table to arrange the wires. Otherwise, communication quality will be affected even though the equipment at two ends is connected.
Serial Port Cable | The synchronous/asynchronous serial port cable is connected to a |
| receptacle. You must select the appropriate cable for the protocol. |
