Unit Description / Title
The software release and serial number of the unit are displayed on the Title screen.
Audio Status
The status of the received audio and the data rate of the codec.
The codec has been designed to Mute the audio signal if end-to-end synchronisation is not
achieved. The data rate shown here is the actual data rate which the codec has achieved end-to-
end synchronisation, and not necessarily the configured mode.
AES Status
The status screen displays information about the AES input data stream.
RX is the status of the AES audio receive signal.
Con = Connected, Dis = Disconnected
FMT is the AES format.

NOTE1: CTS output signal should be used for Flow Control when Auxiliary Data is enabled.
NOTE2: All modes appended by “(alt)” are compatible with codec’s manufactured by APT.
NOTE3: Relay mode enables two sets or bi-directional contact closures. The connection details are shown in the “Manager Input
Port” and “Manager Output Port” sections of this manual.

System Options
The user can modify the global System configurations of the Codec.
Password
The C530xr has two levels of password protection to avoid accidental re-configuration; Edit Lock
and Full Lock.
The user can view all configuration menus but is not allowed to make any changes - the YES
button is disabled. Edit Lock enables ISDN calls to dialled and hanged. Full Lock disables ISDN
dial and hang, however, incoming ISDN calls will be answered.
Loopback
The C530xr can be configured to provide an internal digital loopback of the compressed audio
signal prior to the X.21 / ISDN interface. The loopback function will automatically use the highest
data rate available.
NOTE : The loopback function is not available when operating in Backup Master or Backup Slave modes.
Ethernet Options
The C530xr can be remotely managed via the Ethernet Port. The display will show:-
Inactive,
Negotiation,
100BASE-TX full-duplex,
100BASE-TX half-duplex
10BASE-TX full-duplex
10BASE-TX half-duplex
Ethernet DHCP
When Dynamic Host Configuration Protocol (DHCP) is selected to ON the C530xr will request a
temporary IP Address from the IP Server and thereby simplifying the setup process.

Ethernet Webserver
Firstly configure the appropriate settings for your network in the Ethernet options menu. Once
configured correctly connect the port labelled “LAN” to your router.
On your computer web browser type in the IP address of the codec (http://192.168.0.2).
A Windows Login screen will be displayed. The default Username is “admin” and the default
password is “admin”.
The screen shot below shows the layout of the Webserver :-

12
Email Alert Messages
The codec can be configured via the Ethernet
Webserver to send an Email Alert message
following Sync Loss.
In the Send To This E-mail Address box, type
the e-mail address where the alerts will be
sent. Enter the full e-mail address (for
example, [e-mail]. If you leave
this box blank, no alerts or logs will be sent
to you.
In the Outgoing Mail Server box, type the
name or IP address of the outgoing SMTP
mail server of your ISP (for example,
mail.myISP.com). If you leave this box blank,
no alerts or logs will be sent to you.
In the Subject box, enter the text to be
displayed in the email subject line.
If you leave this box blank, no alerts or logs
will be sent to you.
Email Timing
Once the Email Alert has been configured
correctly, the codec will send an email Event
Log 10 seconds after a Sync Loss has
occurred. The Event Log will then be cleared
and disabled for 15 minutes before being re-
enabled again.
If the codec is unable to send the email
successfully, then the Event Log will be
cleared and returned to the enabled state.

13
REMOTE MANAGEMENT
The C530xr Codec can be configured
remotely by connecting a straight 9 Way D-
Type cable to the MGR IP port, and using the
Standard Windows Terminal Program. To
configure more than one unit at the same
time, the user can connect another straight
9 Way D-Type cable from the MGR OP port of
the first unit, to the MGR IP port of the next
unit, in a “Daisy Chain” manner. There are
no limitations on the number of codecs
which can be linked together for remote
configuration purposes.
On initial connection, the Standard Windows
Terminal Program screen will be blank. The
user should then press the Enter key to clear
the command buffer.
Type “poll” followed by the serial number :-
poll 0108-001 < carriage return / enter >
0108-001>
A prompt of the actual serial number will
appear on the screen. The unit is now ready
to receive commands.
Type “help” for a complete list of commands
and options.
