8AS Cable
Description
An 8AS interface card can be used in four scenarios, where different cables are required. Table 8-62 describes the scenarios and applicable cables.
Cable Type |
Application Scenario |
Description |
|---|---|---|
Financial dumb terminal |
The pin assignments at both ends of the cable are the same. |
|
Telecommunications terminal |
An adapter cable has an RJ45 male plug at one end and an RJ45 female socket at the other end. The cable converts the wire sequences on a dumb terminal to the standard wire sequences for telecommunications devices. The RJ45 male socket of the adapter cable is connected to a straight-through cable, which is connected to a terminal. |
|
Common network device |
An asynchronous serial cable has an RJ45 connector at one end and a DB25/DB9 connector at the other end. |
|
Serial port server |
The wire sequences of twisted pairs in the two RJ45 connectors are determined by the type of signals transmitted from the connected terminal. |

Adapter Cable plus Straight-Through Cable: Connecting to a Telecommunications Terminal
Adapter Cable plus Asynchronous Serial Cable: Connecting to a Common Network Device
Figure 8-41 shows the structure of an asynchronous serial cable.
Table 8-67 lists the pin assignments of an asynchronous serial cable.
Self-made Cable: Connecting to a Serial Port Server
Figure 8-42 shows the structure of a self-made cable.
Table 8-68 lists the pin assignments of a self-made cable.

Connection
- Financial dumb terminal connection: Connect one end of a straight-through cable to the 8AS interface card and the other end of the cable to the dumb terminal.
- Telecommunications terminal connection: Connect the X1 end (RJ45 male plug) of an adapter cable to the 8AS interface card and the other end to a straight-through cable. Then connect the other end of the straight-through cable to the telecommunications terminal. See Figure 8-44.
- Common network device connection: Connect the X1 end (RJ45 male plug) of an adapter cable to the 8AS interface card and the other end to a RJ45 connector of an asynchronous serial cable. Then connect the DB9 or DB25 connector of the asynchronous serial cable to the telecommunications terminal.
- Serial port server connection: Connect the X1 end (RJ45) of a self-made cable to the 8AS interface card, and the X2 end (RJ45) to the serial port server.
