Installation
Programming
The analog telephone lines should be
connected in parallel. Connect the
serial output of the CA-4 to a serial
printer or a PC using a 9 position RS-
232 cable. The RS-232 connector is
configured as shown in the table below.

Battery back-up can be provided to maintain the clock operation. If
battery back-up is desired, remove the cover from the CA-4 and install a
9V battery onto the battery snap. Then remove the backing of the double
back tape on the inside of the cover and press the battery firmly to the
tape. The clock time will be maintained for approximately 24 hours.
B. Clock Battery Back-Up
A. Date and Time
a. Call one of the telecom devices connected to the CA-4 using a Touch Tone phone.
b. When the telcom device answers, enter a ✱and the security code “845464”(V-I-K-I-N-G).
Note: The security code can not be changed.
c. To change the time and date, enter two Touch Tone digits for each parameter.
min hours day month year
Example: 2:30pm March 9, 1998. Enter: 30 14 09 03 98
Note: You must use a leading “0” if the value is less than 2 digits.
d. When finished, hang-up.
a. Connect the serial port of the PC to the DATA port of the CA-4.
b. Establish serial communications (see section C. Setting Up Your Communications Software).
c. To change the time and date, enter two digits for each, in the following order: minutes, hours, date, month
and year. Press the <Enter> key to update the time and date.
Note: You must use a leading “0” if the value is less than 2 digits. If there is an invalid entry, “PROGRAM-
MING ERROR” will appear on the screen. Simply reenter the values and press the <Enter> key again.
d. Once the new programming values have been accepted by the CA-4, the new values will appear on the PC
screen.

The CA-4 has a built-in charging circuit for rechargeable batteries. If a
standard battery is used, Jumper 1 must be removed before installing the
battery (see diagram at right) to disable the charging circuit.
B. Inbound DTMF Screening
The CA-4 does not monitor for ring voltage. The only method of determining whether a call is an “inbound” or
“outbound” call is the Touch Tones recorded. In certain situations Touch Tones may be entered on inbound calls,
such as when an Auto Attendant or voice mail system is called. To compensate for these applications, you may set
a maximum inbound Touch Tone filter. This filter will determine any call that uses fewer Touch Tones than the filter
setting to be “inbound.” All other calls will be labeled “outbound.”

The CA-4 monitors the voltage between Tip and Ring to determine if the line is in use. If the voltage is below 18V DC,
the line is deemed in use and the CA-4 notes the time and date of the call. At this point the call timer is started. While
the line is in use, if any Touch Tones are detected, they are buffered, up to a maximum of 20 digits. When the call is
complete, (minimum 5 sec.) the call timer is saved and all the call data is stored in the call buffer.
Operation
C. Setting Up Your Communication Software
Important: Viking Electronics will NOT support computer software or hardware problems. If you experience these
problems, research your hardware/software instruction manuals or contact the manufacturer’s technical support
department. Start your communication software. For example, “Terminal” is the communication software supplied
with Windows 3.x and “Hyperterminal” is supplied with Windows 95. Configure a profile called “CA-4” as follows:
A. Data Output Modes
1. Buffer Mode
In the “Buffer” mode, the CA-4 will store up to 1820 call records. If the maximum buffer capability is surpassed,
the oldest call records will be purged.
a. Manual Operation - To change the output mode, momentarily press the DATA button. The CA-4 will toggle
between modes. The “Buffer” mode is indicated by a slow flash (1 second on, 1 second off).
b. PC Operation - To enable the “Buffer” mode, enter <Ctrl+B>.
Important: Viking Electronics will NOT support printer problems. If you experience these problems, research your
hardware/software instruction manuals or contact the manufacturer’s technical support department.
Configure the serial printer as follows:
D. Setting Up Your Printer
<Ctrl+X> = Statistics reset
<Ctrl+Z> = Send date, time & mode
<Ctrl+B> = Buffer mode
<Ctrl+D> = Dump mode
<Ctrl+S> = Start/Stop (toggle)
<Ctrl+H> = Halt and return to start
Parity check and carrier detect should be left unselected. Save your settings. This will allow you to retrieve your
settings whenever you wish to download CA-4 data without having to manually set the parameters each time.
Com = that of your serial port (1 - 4)
Baud rate = 9600
Baud rate = 9600
Data bits = 8
In the Buffer mode, call records are held in the CA-4 for later retrieval. In the Dump mode, all stored call data is output
to the serial port. As long as the CA-4 is in the dump mode, subsequent call records are output as soon as the calls are
terminated. Output of the CA-4 can be controlled either manually by using the DATA button on the front panel or by
entering <Ctrl> characters when interfaced with the serial communication software of a PC. Following are the <Ctrl>
characters and their operations:
<Ctrl+A> = ASCII Delimited format
<Ctrl+T> = Tabular format
2. Dump Mode
In the “Dump” mode, all buffered data is downloaded to the RS-232 port. If left in the dump mode, each
additional new call will also be downloaded.
a. Manual Operation - To change the output mode, momentarily press the DATA button. The CA-4 toggles
between modes. The “Dump” mode is indicated by a fast flash (1/2 second on, 1/2 second off).
b. PC Operation - To enable the “Dump” mode, enter <Ctrl+D>.

Note: Communication software menu commands may vary with brands and versions. The commands listed are
only the most common. If your software does not use these menu commands, use the commands that most closely
correspond.
1. Connect your PC to the RS-232 port of the CA-4.
2. From the personal computer, start the communication software and, open the profile as
explained in Programming section C. Setting Up Your Communications Software.
3. From your communication software select “Transfer...” or “Transfer File...,” then “Receive text...” or “Capture
text...”
4. In the file name box, create a name with a .txt extension (Example: data.txt). Click “OK” or “Start.” Your PC is
now ready to receive the call data from the CA-4.
5. Enter <Ctrl+Z>. The CA-4 will respond with time, date and mode, verifying communications between your PC
and the CA-4.
6. Enter <Ctrl+D> to begin dumping the data. The call records will appear in the terminal window of your PC.
Notes: You may momentarily pause and restart the data transfer by entering <Ctrl+S>. Alternatively, you may
also abort and restart the transfer from the beginning by pressing <Ctrl+H> followed by <Ctrl+D>.
7. When the file transfer is complete, click on “Stop” or “Stop Transfer” button.
8. If desired, enter <Ctrl+B> on the PC keyboard to put the CA-4 back into the call “Buffer” mode.
To use the data in a spread sheet, import the ASCII Delimited Text file you have just created and manipulate
the data as necessary.

C. Printer Mode
You may download records individually using the dump mode or store the records and dump all of the records at
once using the buffer mode. Below is a sample printout/terminal screen.
Connect your serial printer to the RS-232 port of the CA-4 and set up your printer as shown in “Programming
section D.” For ease of viewing, the Tabular mode should be used (see B. Data Format, 1. Tabular Format)
3. Deleting Data
To delete all stored data, press <Ctrl+X> (PC mode only).
1. Tabular Format
In the tabular format, the data is spaced to form a table. This is best for downloading to a serial printer.
2. ASCII Delimited Text Format
In the ASCII delimited text format, a text file is produced with commas delimiting the individual data fields. This is
best for downloading to a PC.
Manual Operation - To change the data format, hold in the DATA button. After one second, the CA-4 will
begin flashing the LED, first consecutive five single flashes, then five double flashes and then repeating the
pattern as long as the button is held in. Continue to hold the button down while watching the flashing LED.
Release the DATA button when the LED produces a single flash to put the CA-4 in the tabular mode.
