IBM WebSphere DataPower 7198 Installation And User Manual page 46

The DE-9 serial console cable has a 8-position modular plug at one end and a 9-pin
socket at the other end. This cable includes null modem functionality. The 9-pin
socket connects directly to the 9-pin plug on a PC that is running terminal
emulation software. The DE-9, often called DB-9, 9-pin socket is wired as data
circuit-terminating equipment (DCE) per the EIA/TIA-574 standard.
If your PC does not include a 9-pin serial port but has a USB port:
v You can use a USB-to-serial converter cable, if supplied
v You can use a USB-to DB-9 cable to connect to the supplied cable
v You can create a cable based on the cable pinout specifications in Table 4
If you use the USB serial console cable and your PC does not recognize the cable,
you might need to install the device driver. The drivers are on the IBM WebSphere
DataPower SOA Appliances: Resource Kit CD in an archive file.
v The driver for Windows systems is in the driver/win/ directory.
v The drivers for Mac OS systems are in the driver/mac/ directory.
For driver installation instructions, see the readme file or Installation Guide in the
archive file.
Notes:
Table 4 describes the serial port pinouts for the console connector.
To make the serial connection:
1. Use the appropriate cable to connect from an ASCII terminal or PC to the
2. Ensure that the terminal or PC is configured for standard 9600 8N1 and no
