Structure and Pin Assignments
Trunk Extension Cable
A 120-ohm DB9-to-RJ45 cable is 3 m long by default. If the default length is not enough for cable connection, you can use a 120-ohm trunk extension cable as an extension cable.
When using a 120-ohm trunk extension cable to prolong a 120-ohm DB9-to-RJ45 cable, connect one RJ45 connector of the trunk cable to a network interface connector and the other RJ45 connector to the remote device, as shown in Figure 8-19.
Connection
A 120-ohm DB9-to-RJ45 cable is connected as follows:
- The DB9 connector is connected to a router.
- The RJ45 connector is connected to a network device.
Ordering Information
If 120-ohm DB9-to-RJ45 cables need to be prolonged, configure one network interface connector and one 120-ohm trunk extension cable for each 120-ohm DB9-to-RJ45 cable.
Table 8-30 provides the 120-ohm DB9-to-RJ45 cable ordering information.
