Bench Testing

It is suggested that the receiver be tested before actual
installation; becoming familiar with the connections and
setup of the unit on the work bench will make final instal-
lation more straightforward.
The following items are required:
• 28 V

Power supply

• One telephone line
• One or more dialer or digital dialer control panels

2.2.1 Power Up

When the 28 V

power is applied, the CPM2000 unit

will beep for approximately 1-2 minutes during system ini-
tialization. The buzzer will deactivate as soon as the
CPM2000 software initializes and is running. The LCD dis-
play on the CPM2000 should display 'Primary'. If the Line
Cards do not have telephone lines connected, the
DRL2000 modules will activate 'Line Fault' lights. The tele-
phone line should be connected to the POTS jack at the
back of the DRL SUBRACK. As soon as the line card
detects a phone line, a line restore message will be sent to
the printer and computer output. If the phone line is
removed, a line fault message will be sent to the printer
and computer output.
If there is no computer or printer connected, a trouble
message will be displayed on the CPM2000 LCD and the
'ACK' light will flash. Press the [ACK] button to silence the
CPM2000 buzzer.
The watchdog LED on the line card should flicker as soon
as it is initialized. The Trouble LED will activate if the line
card is not receiving a poll from the CPM2000. As soon as
the line card responds to the polling, the Trouble LED
should deactivate.

2.2.2 Operation with Default Programming

Without any changes to the factory default programming,
the receiver operates as follows:
• Answers incoming calls on the first ring
• Sends 2300 Hz as the first handshake
• Sends 1400 Hz as the second handshake
• Sends dual tone as the third handshake
• Sends SIA FSK tone as the fourth handshake
• Sends ITI , Modem IIE/ IIIa

tone as fifth handshake

• Sends Modem II tone as sixth handshake
• Receives all communication formats, except for: 3/2, 4/1

express, 4/2 extended and 4/2 checksum.

• The above formats can be manually selected.
• Signals can be displayed on the debug output computer

as they are received. The signals are then sent to the
parallel printer and computer connected to serial port
COM1 or to the 10BT connector. The default event
codes described in the 'DRL2000 Library Decoding and
Event Codes Table' will be used with the Sur-Gard auto-
mation communication protocol to send signals to the
computer, if connected.

• If a computer is not connected, press the [ACK] button

on the CPM2000 module to silence the buzzer.

2.2.3 Debug Output

The debug output is another means of accessing the line-
card's programmed options and diagnostics features. A
debug cable is required to connect by serial communica-
tion from the line card to a standard PC running Windows
9x/2000/XP.

2.2.4 Debug Cable Connectivity

• Connect the RJ45 end of the debug cable to the debug

jack on the front of the line card or to the debug jack of
the paddle board on the back of the sub-rack.

• Connect the female DB-9 connector to the serial port of

a computer (COM1 port - usually DB-9 male, COM2
port - DB-25 female).

2.2.5 Debug Software Setup

• Using WIN95, point and click on the 'START' button.

Access 'Programs' -> 'Accessories' -> 'HyperTerminal'.
Once in the HyperTerminal window, point and click on
'Hypertrm.exe' icon.

• A connection description window should appear. A

prompt should appear on the 'Name' category. Type a
name. Point and click on the 'OK' button.

• A phone number window should appear. Choose the

direct to COM port required for connection and point
and click on 'OK'.

• COMX properties windows should appear. The configu-

ration should be:

• Bits per second: 19200
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None
• Point and click on the 'OK' button after setting the con-

figuration.

• The HyperTerminal window should appear. Press any

button. The debug menu will be displayed.

2.2.6 Button Commands

:This button will display the address of the line card. The

address includes the shelf and slot number of the line
card making each line card unique.

:This button will initiate the download of a file to the

line card.

:This button will enable the user to dump the current

programmed options of the line card or set an option
to a particular value.

:Sets the message priority to be displayed. This is useful

for debugging purposes only.
