1. Mark the wiring for all devices connected
to the SDI bus with the numbers of the
terminals.
2. Disconnect all devices from Terminal 29
through Terminal 32.
3. Set all DIP switches on a known good
keypad to ON (address number 1).
4. Directly wire the keypad to Terminal 29
through Terminal 32.
5. Using the D5200 Programmer or RPS,
go into GV2MAIN→Command
Centers →Command Center
Assignments.
6. At Command Center Assignment
Address “1”, ensure that Scope is set to
“Panel Wide.”
If using the D5200 Programmer,
disconnect it from the control panel and
release the reset pin.
Does the keypad operate correctly?
The SDI circuitry on the control panel
failed. Remove and replace the control
panel.
The SDI bus wiring has a short. Refer to
TTP46 Shorted Wiring on page 98.
Use a digital voltmeter (DVM) and measure the input
power voltage on the NIM. Set the DVM to VDC.
Connect the red lead to the positive (+) terminal on
the NIM. Connect the black lead to the negative (
−)
terminal. Refer to Figure 33 on page 78 for the
DX4020, or in Figure 34 on page 78 for the
D9133TTL-E.
Is the voltage +12 VDC to +13.8 VDC?
The power wiring between the control panel
and the NIM has an open condition. Refer to
TTP47 Open Wiring on page 100.
Use a digital voltmeter (DVM) and measure the
voltage on the data circuit to the NIM. Connect the
red lead to Terminal G (green). Connect the black
lead to the negative (−) terminal. Refer to
Figure 33
on page
78 for the DX4020, or in Figure 34 on page
78 for the D9133TTL-E.
The voltage on these terminals is not a steady
voltage.
Is the lowest voltage indicated on the DVM less
than 3.5 VDC?

The network communication parameters for the
control panel are not correct. Use the RPS
software or the D5200 Programmer and
perform the programming procedure. Refer to
Using RPS (RAM IV) on page 83 or Using a
D5200 Programmer on page 84.
The data circuit between the control panel and the
NIM has an open condition. Refer to TTP47 Open
Wiring . on page 100
Generate a signal by latching and unlatching the reset pin
on the control panel. Observe the serial transmit (SER-TX)
LED and the serial receive (SER-RX) LED on the NIM. Refer
to
Figure 37 and Table 44 on page 80 for the DX4020, or
Figure 38 and Table 45 on page 82.
Do the SER-TX and SER-RX LEDs flash?
Generate another signal and observe the Xport LEDs
on the DX4020 or the Ethernet Status LEDs on the
D9133TTL-E. Refer to
Figure 39 and Table 46 for the
DX4020 on page Figure 4080, or and Table 47 for
the D9133TTL-E on pages
81 and 82.
Do the LEDs flash or light?
Check the Ethernet network RJ-45 connection
and the Ethernet cable and connections.
Use a laptop PC and perform the procedure
described in Using the PING Command on page 88.
Does the ping command generate four replies?
