Tab le 4 .1 Modes Allowed by Control Panel
NOTICE!
When using the PSTN (Contact ID) over GSM mode on a GV3 Series control panel, ensure that
the “C” character is dialed before the central station’s phone number. The "C" character
disables dial tone detection after the first DTMF digit is dialed.
NOTICE!
Bosch recommends that when using GSM mode, always enter a 10-digit phone number in the
control panel. This is because the SIM card might have originated in a different area code from
the installation location.
DUAL
NOTICE!
When using the PSTN (Contact ID) over GSM mode, the control panel must be set up for
DTMF (tone) dialing only.
4.1 Use Short Message Service (SMS) to Configure the ITS-DX4020-G
The ITS-DX4020-G supports configuration by SMS. You can send the SMS via mobile phone to
the ITS-DX4020-G. The SMS string follows a specific format. If the configuration message
exceeds 160 characters, you must send multiple messages. Refer to Section 4.1.2 Compose
the Configuration SMS, page 19 for details.
When the ITS-DX4020-G receives the final valid part of an SMS message, it accepts the
configuration. The ITS-DX4020-G waits as long as the CONFIG MODE jumpers are shorted
together with the supplied jumper plug.
NOTICE!
To allow the receipt of SMS data, the CONFIG MODE jumper pins must be shorted together
with the supplied jumper plug. Refer to Table 4.6, Page 21, for LED activity.
If the CONFIG MODE jumper pins are not shorted together, incoming SMS data is discarded.
4.1.1 Enter CONFIG MODE
Ensure that the CONFIG MODE jumper pins are shorted together with the supplied jumper
plug. The STATUS, CELL IP, and AUDIO ACT LEDs start a scrolling pattern.
F01U133268 | 03 | 2010.05 Installation and Operation Guide Bosch Security Systems, Inc.
GPRS/GSM IP Communicator Configuration | en 19
4.1.2 Compose the Configuration SMS
Use the appropriate SMS template for the selected mode of operation, and compose the
configuration SMS message on your mobile phone. SMS can contain only 160 characters.
Refer to Section Multiple SMS Messages (for Messages Longer than 160 Characters), page 20 for
instructions for sending a multiple SMS configuration.
The templates below contain only the essential configuration IDs. For additional configuration
IDs, refer to Table 4.9, Page 30.
NOTICE!
Separate each ID or value pair with a line feed (<LF>), a carriage return (<CR> or
< ENTER>), or a semi-colon <;>. Because of phone and carrier differences, Bosch
recommends using semi-colons to create and send SMS messages (for example,
%1;1=4020G;10=Airnet1;14=88;17=2;!). To allow spanning of configuration across multiple
messages, each SMS starts with the sequence number followed by the command line
separator.
Any of these characters is acceptable to separate command lines. Refer to your cellular
phone’s documentation for available characters.
Refer to Table 4.1, Page 18 for information about the modes allowed for your control panel.

57 GPRS session
timeout
1 to 255 hrs (4 hrs) If no IP over GPRS communication occurs within the
GPRS session timeout period, the ITS-DX4020-G
sends a message to keep the current session alive,
ensuring that the network path is active. To avoid
connectivity delays, set the GPRS session timeout
to fewer hours than your carrier's session expiration
period to avoid connectivity delays.
58 Trouble reporting
delay time
0 to 65535 sec (120 sec) When low signal strength, SIM card missing, or
unable to register on the network is detected for
longer than the time entered in this parameter, the
ITS-DX4020-G stops responding on the bus to
indicate a Trouble condition to the control panel. No
information is sent to the control panel. The next
attempt by the control panel to poll, or send a
message to the ITS-DX4020-G, fails. The control
panel then creates a trouble condition. When signal
strength is detected, it must remain restored for the
amount of time entered in this parameter before the
ITS-DX4020-G sends signals again.
59 Enable low signal
strength reporting
– 0 = Disabled
– 1 = Enabled
When enabled, the ITS-DX4020-G sends a trouble
signal to the control panel if the signal strength falls

4.3 Polling Configurations
Plan carefully when selecting the control panel poll time, ACK wait times, control panel
retries, ITS-DX4020-G GPRS ACK timeouts, and D6x00 Receiver poll and ACK wait times.
Having the wrong or improper settings could cause trouble conditions when the network
carrier performs maintenance, and increased data volumes that could effect your monthly
cost. Your settings for these parameters determine how the system works, but depend on the
security level needed.
4.3.1 High Security Application (bank, jewelry store, UL fire, and so on)
Polling times are typically less than 20 min. Path integrity is critical, and short interruptions in
network service are indicated at the premise and central station. The following High Security
Application recommendation assumes the ITS-DX4020-G is the primary communication device
with no backup.
Control Panel Settings
– Poll Rate: 60 sec
– ACK Wait: 13 sec
– Retry Count: 5
ITS-DX4020-G Settings
– GPRS ACK Timeout: ACK wait (13) x Retry Count (5) + ACK Wait (13) = 78 sec
– GPRS Session Timeout: Must be greater than control panel poll time (60 sec) + GPRS
ACK timeout (78 sec). The minimum GPRS session timeout setting is 1 hour; the default
4 hour setting is acceptable.
D6x00 Receiver Settings
– Control Panel Poll Rate: 60 sec
– ACK Wait: 78 sec
Bosch Security Systems, Inc. Installation and Operation Guide F01U133268 | 03 | 2010.05
32 en | Configuration GPRS/GSM IP Communicator
4.3.2 Medium Security Application
Polling times are typically 1 to 4 hours. Path integrity is important, and short interruptions in
network service might be indicated at the premise and central station. The following Medium
Security Application recommendation assumes the ITS-DX4020-G is the primary
communication device with no backup.
Control Panel Settings
– Poll Rate: 3 hours
– ACK Wait: 300 sec (5 min)
– Retry Count: 5
ITS-DX4020-G Settings
– GPRS ACK Timeout: ACK wait (300 sec) x 2 = 600 sec
By setting the GPRS ACK timeout less than the retry count, the ITS-DX4020-G can
reconnect to the network if the carrier dropped the connection or for short maintenance
interruption outages.
– GPRS Session Timeout: Must be greater than control panel poll time (3 hours) + ACK
wait (5 min) x Retry Count (5) + ACK Wait (5 min) = 3 hours and 30 min. The GPRS
session timeout default setting of 4 hours is acceptable.
NOTICE!
If you use a control panel poll rate of 4 hours, change the default GPRS session timeout to
5 hours. Ensure that your SIM service provider’s session timeout is greater than 5 hours.
Check the information that came with the SIM card. If the carrier’s session timeout is less
than your GPRS session timeout, the communication path is dropped by the carrier and the
event message is not received until a new connection is made, delaying your event messages
from being delivered when expected. To ensure the communication path is not dropped, set
the poll rate to less than the carrier timeout (for example, 2 hours).
D6x00 Receiver Settings
– Control Panel Poll Rate: 4 hours
– ACK Wait: 15 sec
NOTICE!
To set the control panel poll rate by the hour, ensure that the D6x00 Receiver has D6200CD
V1.35 firmware or later.
Because the Bosch D6x00 Receivers only have hours and seconds settings, the receiver would
have to be set to 4 hours instead of 3 hours and 30 min. The receiver can only support up to
255 sec maximum for the ACK wait time.

4.3.3 Backup or Low Security Application (residential or other once-a-day reporting location)
Polling times are typically 12 to 24 hours. Path integrity is only tested once or twice a day, and
short interruptions in network service are generally not indicated at the premise and central
station. Using settings similar to the following allows the system to recover from short
outages without causing trouble conditions at the premise. The following Backup or Low
Security Application recommendation assumes the ITS-DX4020-G is the primary
communication device with a different technology backup (PSTN or Wired IP).
Control Panel Settings
– Poll Rate: 24 hours
– ACK Wait: 300 sec (5 min)
– Retry Count: 10
ITS-DX4020-G Settings
– GPRS ACK Timeout: ACK wait (300 sec) x 2 = 600 sec
By setting the GPRS ACK timeout less than the retry count, the ITS-DX4020-G has time to
reconnect to the network if the carrier dropped the connection or for short maintenance
interruption outages.
– GPRS Session Timeout: Must be greater than control panel poll time (24 hours) + ACK
wait (5 min) x Retry Count (5) + ACK Wait (5 min) = 24 hours 55 min. This property’s
default 4 hour setting must change. Check with the SIM service provider to determine the
maximum time allowed for a session. Your GPRS session timeout must be less than this
value.
NOTICE!
Several SIM service providers only support up to 24 hour session timeout. Check the
information that came with the SIM card. If the carrier’s session timeout is less than your
GPRS session timeout, the communication path is dropped by the carrier and the event
message is not received until a new connection is made, delaying your event messages from
being delivered when expected. To ensure the communication path is not dropped, set the
poll rate to less than the carrier timeout (for example, 18 hours).
D6x00 Receiver Settings
– Control Panel Poll Rate: 25 hours
– ACK Wait: 15 sec
NOTICE!
The D6x00 Receiver must use D6200CD V1.35 or later to support hour selections.
NOTICE!
Signal outages can be caused by routine upgrades and maintenance of the mobile towers. On
average, these outages can last from 1 to 15 minutes. One option to minimize the number of
signal failures caused by these outages, reduce the poll rate setting in the control panel to half
of the poll rate setting in the central station receiver.

4.4 SIM Card Data Usage
NOTICE!
The security level you need determines which SIM card data plan you should use. If you obtain
a data plan for once-a-day test messages, but you set up polling for 60 sec, you will receive a
larger-than-expected cellular bill. It is important that you chose a data plan that matches your
application.
– Poll Message or Event Message: ~100 bytes
– RPS Sessions: This setting depends on the RPS tasks you perform (for example, full
upload/download of programming data, history retrieval, diagnostics) and the number of
times you access the control panel. On average, such usage could range from 10 kb to
100 kb.
Other factors such as the number of session timeouts received and so on will also increase
the data usage.
Based on 60 sec polling and 5 events/day, you can expect to use ~5 MB of data per month not
including RPS usage.

5 Testing
1. Configure the control panel for communication routes.
Refer to your control panel’s documentation for programming instructions.
2. Send a test alarm using the configured route(s), and verify receipt of the alarm at the
central station.
3. If incoming GSM calling is enabled, initiate a phone call to the control panel.
5.1 GSM Trouble Indication
The ITS-DX4020-G module activates the phone voltage after GSM registration finishes. The
module removes the phone voltage if it detects a communication problem when being used in
PSTN (Contact ID) Over GSM Mode. If all trouble conditions restore, the phone voltage is
automatically reapplied. This allows legacy control panels with phone line voltage monitors to
support the module and display communication trouble signals. The removal and restoral of
the phone voltage from a trouble condition is controlled by the trouble reporting delay time
parameter.
The following conditions cause the phone voltage to be removed:
– SIM missing
– Low signal strength
– Not able to register on the GSM network
5.2 Firmware Version
Use the LED DIS function to determine the firmware version of the ITS-DX4020-G module
without a USB connection. When you first install the LED Disable jumper, the LED flashes the
firmware version as a series of three flashes (for example, 1 - 4 - 3 flashes signifies
firmware version 1.4.3).
