Contents Introduction

Connecting to the codec

Accessing XACLI

XACLI can be accessed through Telnet and SSH via the LAN
interface or through the COM port by connecting a serial cable
to the serial interface connector, referred to as the COM port.
The COM port (RS-232) is a 9-pin, female, D-sub connector
located on the back of the Codec C–Series. The connector i
marked with the text: Camera Control.
The port is configured as a DCE (Data Communications
Equipment). The COM port (RS-232) is default set to 38400
baud, 8 data bits, none parity and 1 stop bit from factory. The
port may also be referred to as the Data port.

Telnet/SSH login

Telnet is by default disabled. This can be changed with a
configuration command: xConfiguration NetworkServices
Telnet Mode: On/Off
•
xConfiguration NetworkServices Telnet Mode: On
Telnet/SSH login
•
User name is: admin
•
The default passworrd is blank.

Serial port login

The serial port is password protected by default. The password
protection may be configured.
•
User name is: admin
•
The default passworrd is blank.

Serial port configurations

On the serial port the baud rate and password protection may
be configured.
The configuration command for the baud rate is:
xConfiguration SerialPort BaudRate:
<9600/19200/38400/57600/115200>
•
xConfiguration SerialPort BaudRate: 38400

The configuration command for login required is:
xConfiguration SerialPort LoginRequired: <On/Off>
•
xConfiguration SerialPort LoginRequired: On

Reboot

The system requires a reboot for the changes to baud rate and
password protection to take effect.
NOTE: When system boots up the baud rate of the boot
messages is 38400 regardless of the baud rate set in the
codec application.
Hardware & Cabling (RS-232)
The pin outs for the RS-232 are defined in the tables to the
right. Observe that the DTE (Data Terminal Equipment), could
be a PC or any other device capable of serial communication.
Cable. A straight-through cable should be used between
the RS-232 port and the DTE. The lower table shows the
recommended cable-wiring scheme when connecting the
Codec C–Series to a PC through RS-232.
DTR and RTS are ignored. DSR, CD, and CTS are always
asserted, while RI is not used.
Troubleshooting (RS-232)
If communication cannot be established between the PC/
terminal and the Codec data port, the following should be
checked:
1. Verify that the serial cable is a straight-through 9-pin to
9-pin cable.
2. Confirm that the configuration of the PC/terminal's serial
RS-232 port is identical to the configuration of the RS-232
port.
3. Verify that the PC/terminal's serial RS-232 port is working
properly by connecting it back-to-back to another PC/
terminal and send characters in both directions.
