4.12 Connecting the Console Terminal
A console cable is provided with the product package to connect the SDM-9220/9230 to
the console terminal. This is a standard TIA-232 (V.24) straight-through cable with DB-9
female connectors at both ends (Ordering part number: 161-0703-001).
To connect the console terminal to the SDM-9220/9230 unit:
1. Install one end of the console cable onto the SDM-9220/9230 console port, labelled
CONSOLE on the rear panel. Refer to Figure 5-1 and Figure 5-2 on “Rear View of
the SDM-9230 UAC” on page 5-2 .
2. Connect the other end of the cable to a COM port on the console terminal or PC, or
to a modem for dialup connection to a remote console.
4.12.1 Important Console and Modem Settings for Startup
The console port performs autobaud detection when in auto-sensing mode. The SDM-
9220/9230 will set the speed of the console port as soon as it detects an active connection.
CAUTION:
:
For a trouble-free startup, you must set the console terminal and
modem as follows:
• Console terminal: The default console speed is 9600 bps during bootstrap ini-
tialization, boot sector validation and system initialization. Set your console ter-
minal emulator to 9600 bps to view all SDM-9220/9230 system status
messages on-screen during the startup sequence.
• Modem: Configure your modem with the following AT commands:
- at&d0 to ignore DTR. The SDM-9220/9230 cannot supply DTR to the
modem when in auto-sensing mode (the default setting).
- ats0=1 for Auto Answer mode
- at&w0 to save the modem configuration.
Once system startup has completed successfully, the SDM-9220/9230 enters auto-sensing
mode automatically. At that point, you can change your console speed, if desired.
• Available console speeds are 1200, 2400, 4800, 9600, 19200, 28800, 38400,
57600 and 115200 bps. The equipment you connect to the console port must
operate at one of these speeds.
