Serial Port Cable 53
LAN Switch. Straight-through network cables are delivered along with the
router.
■ Crossover network cable — The sequences of the wires crimped at the RJ-45
connectors of the two ends are different. The cable is used in the connection
between the terminal device, such as a PC or a router, and another terminal
device. You can create this cable yourself, if necessary.
Table 27 describes straight-through network cable pinouts.
Table 28 describes crossover network cable pinouts.
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 DB-50
receptacle. You must select the appropriate cable for the protocol.
