12.5.2 Network Interface Modules
The Bosch Security Systems, Inc. DX4020 Network
Interface Module is a four-wire powered SDI device
that provides connection for two-way communication
over Ethernet networks to D9412GV3 and
D7412GV3.
For programming information on enhanced
communications, refer to the D9412GV3/D7412GV3
Program Entry Guide (P/N: F01U170807).
The DX4020 can be installed up to 305 m (1000 ft)
from the control panel using 0.8 mm (22 AWG) wire.
The ITS-DX4020-G GPRS/GSM IP Communicator
enables two-way IP or dialed communication over a
commercial GPRS/GSM network. Typical applications
are event reporting to a central monitoring station and
remote access to Bosch intrusion control panels.
The ITS-DX4020-G GPRS/GSM IP Communicator
has two modes; GPRS uses Modem IIIa
2
; and GSM
uses Contact ID.
For programming information refer to the
ITS-DX4020-G GPRS/GSM IP Communicator
Installation and Operation Guide (P/N: F01U163066
).
12.5.3 Address Settings
The DX4020 has specific DIP switch settings for SDI
Addresses 88 and 92 when using the DX4020 for
Remote Programming Software (RPS) or enhanced
communications in a local-area network (LAN) or
wide-area network (WAN) environment. Refer to
Figure 30 for the correct switch settings.

12.5.4 Supervision
Supervision of the DX4020 and D9133DC at SDI
Address 88 and 92 is available through programming
that ensures operation between the module and the
control panel.
If supervised and the module does not respond to
control panel supervision polls, SERVC SDI 88 or
SERVC SDI 92 appears at the keypad. The report to
the receiver includes the address of the troubled
module indicating which module needs service.
