Initial Actions
• Obtain from the network administrator and record
the following information for the network interface
module (NIM):
Initial Actions
Make sure that you have performed the

− Netmask address
• Ensure that Jumper P2 in the network interface
module (NIM) is in the enabled position. Refer to
Procedure
To test the operation of the control panel and the local
phone line, program the control panel to communicate with
the receiver in Technical Support:
on page 79 for the DX4020 and Figure 37 Figure 38
on page
80 for the D9133TTL-E.
• Ensure that the power and data connections
between the control panel and the network interface
module (NIM) are connected correctly and securely.
Data connections are shown in
1. Using RPS or your D5200 Programmer, select
GV2MAINÆPanel Wide ParametersÆPhone.
2. Record the primary central station phone number that
the control panel currently uses.
on page Figure 33
78 for the DX4020, or in on page 78Figure 34 for
the D9133TTL-E.
3. Replace the current phone number with
1 800 289
0096 CCCC 4119.
Procedure
Programming CCCC before the last four digits of the
phone number allows a 12-second pause for the
Observe the BUS-XMIT and BUS-RCV (DX4020) or
BUS TX and BUS RX (D9133TTL-E) LEDs on the
network interface module (NIM). Refer to
automatic attendant to request the extension number.
Figure 37 and
If using the D5200 Programmer, you must use both
Table 44
lines to program the phone number. Use all digits in the
first line before continuing on the second line.
4. Place a telephone butt set in the Monitor position, and
connect the set to the TIP and RING posts on the
control panel. Refer to
Figure 32 on page 74.
5. Call Technical Support using the control panel. Watch
or listen for each indicator described in Table 43 on
page
72 during the two-way communication sequence.
Does the communication sequence finish successfully?
Replace the control panel. Repeat the test.
Call the central station to verify that the receiver is using the
correct ACK tones for the control panel.
For modem format: Modem IIIa
2
ACK tone
For BFSK format: 2300 Hz ACK tone
Is the receiver programmed with the correct ACK tones?
Ask the central station to program the receiver with
the correct tones.
If the central station does not provide a new
primary phone number, reprogram the control
panel with the original primary phone number
recorded earlier in this TTP.
Ask the central station to provide a phone number for a
different receiver or a different carrier.

Table 45 on page 80 for the D9133TTL-E.
Are the BUS-XMIT and BUS-RCV (DX4020) or BUS
TX and BUS RX (D9133TTL-E) LEDs flashing?
Check the address DIP switches on the NIM.
Refer to
Figure 35 on page 79 for the DX4020
and Figure 36 on page 79 for the D9133TTL-E.
Are the DIP switches set for address 88?
Set the DIP switches for address 88.
After changing the address, power the
NIM off then on.
Check the operation of other devices connected
to the control panel SDI bus.
Are other SDI devices working?
