Bosch Security Systems, Inc. | 5/07 | 4998122718-02 5
1.0 Introduction
The C900TTL-E Dialer Capture Module (C900TTL-E)
is designed to link a control panel’s digital dialer (data
output) to an Ethernet connection on a local area
network (LAN) or wide area network (WAN).
When the dialer has data to report, the C900TTL-E
provides the signals and voltages necessary to simulate
a public switched telephone network (PSTN)
connection to the central station. The C900TTL-E then
decodes the digital dialer message and delivers the
decoded signals through the Ethernet connection to the
Conettix D6600 Communications Receiver/Gateway
(D6600). When the D6600 acknowledges receipt of the
message, the C900TTL-E sends an appropriate
acknowledge message to the dialer. This protocol
maintains true end-to-end security.
The C900TTL-E has three modular jacks:
•TELCO for connection to the public switched
telephone network (PSTN)
•PANEL for connection to a digital dialer using a
telephone cord
•ETHERNET for connection to the network.
In Intercept Mode, the C900TTL-E connects the digital
dialer to a LAN or WAN. In Fallback Mode, the
C900TTL-E connects the PSTN to the dialer, shunting
itself out of the phone circuit. Intercept Mode is
maintained only if the C900TTL-E CPU is functioning
(Output 1 held low). This ensures the Fallback Mode if
an operational failure occurs.

2.1 Mounting
The C900TTL-E is static sensitive. Ensure
that you touch earth ground before
handling the circuit board to discharge any
static electricity in your body.
Example: Run the ground wire to the
enclosure before handling the circuit
board. Hold the ground wire (or use a
ground strap) and install the circuit board.
2.1.1 Using the Optional Mounting Plate
An optional mounting plate (P/N: 40182) is available
for mounting the C900TTL-E on the door of a
control panel (D8103) or a fire control panel
enclosure (D8109). The D8108A Attack Resistant
Enclosure cannot be used.
Mounting a C900TTL-E in a control panel
enclosure is approved by UL only when
used with a DS7400Xi as shown in
Figure 5 on page 8.

2.2 Wiring
The C900TTL-E can be used with a variety of control panels (refer to Figure 16 on page 25). This section provides
instructions for wiring the C900TTL-E to a DS7400Xi.
The C900TTL-E intercepts the phone line between the telco service and the control panel, making the
control panel’s phone line monitor inactive. If phone line monitoring is required, use an external phone
line monitor, such as the DS7481 (available from Bosch Security Systems, Inc.).
The loss of network connectivity causes the open collector Output 2 on the C900TTL-E to de-activate
(open). This is useful because this output can be connected to a 24-hour zone on the control panel. If
the control panel needs a relay output instead of an open collector output, an optional D130 Relay
Module (available from Bosch Security Systems, Inc.) for network monitoring is required.
Refer to Figure 5.

The DS7400Xi is the only control panel that is approved by UL to be wired in the same enclosure. All
other control panels must be in a separate enclosure to receive UL approval.

2.3 Input/Output Functions
2.3.1 Inputs
The C900TTL-E has three inputs monitored by A/D
converters:
•Input 1 (IN1): Used as an EOL supervised loop. If
input status reports are enabled by the D6600
using Conettix D6200 Programming and
Administration Software, any voltage below
1.66 VDC is reported as a short to the D6600. Any
voltage above 3.33 VDC is reported as an open-
circuit condition. Input 1 must have the
10 kΩEOL resistor.
Input 1
−Supervised
−10 kΩend of line (EOL) resistor
−Power-Limited
•Input 2 (IN2): Used for Intercept Inhibit. If
input 2 exceeds 5.5 VDC, the C900TTL-E is
immediately forced into Fallback Mode for a
minimum of two min. Input 2 must be low for at
least 5 sec to be considered low. If input 2 is not
used, it can remain disconnected.
•Input 3 (IN3): Used for Intercept Override. If
input 3 exceeds 5.5 VDC for 5 sec, the
C900TTL-E enters into Fallback Mode. If input 3
goes low, the C900TTL-E returns to Intercept
Mode. If this is driven by a ground start relay
output, the C900TTL-E stays in Intercept, except
when the dialer begins to dial. Input 3 cannot force
an intercept if the C900TTL-E is in Fallback
because of an error, command, or input 2 high. If
input 3 is not used, it can remain disconnected.
Inputs 2 and 3
−Not Supervised
−Power-Limited
Do not use Inputs 1, 2 and 3 for UL Fire
listing. They can be used for other
purposes.

2.3.2 Outputs
The C900TTL-E has four open-collector outputs:
•Output 1 (OUT1): Active (shorted to ground)
when the CPU is operating normally. If the CPU
fails to operate or loses power, Output 1 opens.
Connect Output 1 from the C900TTL-E to a
24-Hour zone on the control panel. This 24-Hour
Zone alarm report allows the digital dialer (if used)
to indicate a failure of the C900TTL-E to the
central station, or to locally annunciate a failure if
the C900TTL-E’s CPU fails.
Outputs 1 through 4
−12 VDC max (separately energized)
−Maximum Sink Current: 25 mA
−Not Supervised
−Intended for connection to power
limited sources only.

C900TTL-E |Installation Guide | 2.0 Installation
10 Bosch Security Systems, Inc. | 5/07 | 4998122718-02
•Output 2 (OUT2): Active (shorted to ground)
when the D6600 is operating properly, and open
when the D6600 fails to respond to or
acknowledge a package sent from the
C900TTL-E.
Connect Output 2 from the C900TTL-E to a
24-hour zone on the control panel. This 24-hour
zone alarm report provides a means for the digital
dialer (if used) to indicate to the central station a
failure of the C900TTL-E, or to act as a means to
annunciate a failure locally if the network
communications path fails.
•Output 3 (OUT3): Active (shorted to ground)
when the C900TTL-E is in Intercept Mode.
•Output 4 (OUT4): Controlled by command from
the D6200/D6600 (default is open).
Do not use Outputs 3 and 4 for UL Fire
Listing. They can be used for other
peripheral devices.
Optional D130 Relay Modules (available
from Bosch Security Systems, Inc.) might
be needed if the control panel requires a
relay output instead of an open collector
output.

3.0 C900TTL-E Setup
3.1 Setting the DIP Switches
A 10-position DIP switch (Figure 9) programs the
C900TTL-E. The programming depends on the
application and dialer format of the control panel to
which the C900TTL-E is connected. DIP Switch
positions 1 through 4 and 10 work together to program
the dialer format for the C900TTL-E. Refer to Table 2
below and Table 3 on page 12 for DIP switch settings
and functions, and expected digital dialer protocol for
Dialer Format switches 1 through 4.
Figure 9: C900TTL-E DIP Switches
The C900TTL-E must emulate a phone line
and a digital receiver. It must be
programmed to recognize the format it
receives from the control panel.

1If an error occurs in the Intercept Mode, the C900TTL-E automatically switches back to telco line.
2If the D6600 does not acknowledge a report that was intercepted by the C900TTL-E within the programmed time, the digital dialer hangs up
and retries the message transmission. The programmed time is measured as a failed message transmission at the digital dialer. Based on the
number of hang-ups, the C900TTL-E switches to Fallback Mode.
3The elapsed time between polls from the C900TTL-E when idle (not expecting a dialer acknowledgement) requires C900TTL-E version 1.11
or later for a 75 sec poll with DIP Switch 7 OFF. Otherwise, the poll is 30 sec with DIP Switch 7 OFF.
4Requires C900TTL-E version 1.10 or later. This DIP switch must be ON if the D6600 is set for NNC mode.
Any error forces the C900TTL-E to switch the control panel dialer to the Fallback (phone line backup)
position for two minutes the next time the control panel seizes the line if:
•DIP Switch 5 is ON and DIP Switch 6 is OFF, or
•DIP Switch 5 and 6 are OFF, and
•The seizure occurs within two minutes.
Intercept errors are always reported to the D6600. If the D6600 does not acknowledge a signal
intercepted by the C900TTL-E in the proper amount of time, the control panel digital dialer hangs up
and retries the message transmission.

dialer does not seize the line, this condition ends after two minutes.
2If the dialer sends a valid message, the LED returns to a blinking green status. If the dialer hangs up, an intercept error is generated. The
alternating LED also occurs when the line is seized, but no transaction is occurring (for example, the C900TTL-E is waiting for the dialer to
return on-hook). This situation occurs when the C900TTL-E returns to Intercept Mode, or while the dialer has seized the line.

3.2.3 Ethernet/Serial Status LEDs
The C900TTL-E has four Ethernet/Serial status LEDs (Items 1, 2, 3, and 4 in Figure 10 on page 13). These LEDs
flash until the C900TTL-E connects to the Ethernet network. If the LEDs continue to flash, the C900TTL-E is
having trouble connecting to the Ethernet network. The Ethernet Network Link LED should be on and remain
steady when a connection is established with the Ethernet network. Refer to Table 6.

3.3 Fallback Mode
In fallback operation, the C900TTL-E connects the PSTN to the dialer and the dialer to the telco, shunting itself
out of the phone circuit. Intercept mode is maintained only if the C900TTL-E processor is running, and no errors
occur. “Fallback Mode” is ensured if a CPU lockup occurs.
3.4 Dialer Interaction
Table 7 shows the conditions under which the C900TTL-E goes into Fallback Mode. The C900TTL-E returns to
Intercept Mode only when all “Until” conditions are met.

4.0 IP Address Configuration
Setup Instructions
4.1 Factory Programmed Default IP
Address
The C900TTL-E Dialer Capture Module Network
Adapters are shipped with the default IP address
192.168.000.2.
The default IP address is not used for any
of the Bosch Security Systems, Inc.
functions. This information is supplied only
to assist the technician if an Address
Resolution Protocol (ARP) failure command
occurs. It might be useful to know the
default IP address if the ARP commands
fail. However, this occurrence is not likely.
Contact Bosch Security Systems, Inc.
Technical Support at [phone] with
questions.
4.2 Identifying the MAC Hardware
Address
If you already know the IP address of the
C900TTL-E and it was previously
configured, go to Section 4.5 Using Telnet
to Finish the Configuration on page 18.
Before you can program the IP address of the
C900TTL-E, find the media access control (MAC) or
hardware address of the C900TTL-E.
The MAC address is hard-coded into the
C900TTL-E during its manufacture and
cannot be changed. The address is six
bytes (12 digits) in length.
Refer to Figure 11 for an example of a
MAC address.
Figure 11: Example MAC Address Label
The MAC address label is located on the
side of the metal enclosure.
Record the address for future reference.
4.3 Obtaining an IP Address
If you are using Dynamic Host
Configuration Protocol (DHCP), you do not
need to obtain an address from the network
administrator.
If you are not using DCHP, provide the
MAC address to the network administrator.
The network administrator assigns an IP
address for your C900TTL-E.
An IP Address is an identifier for a computer or device
on a transmission control protocol/internet protocol
(TCP/IP) network. Networks that use TCP/IP route
messages based on the IP address of the destination.
The format of an IP address is a 32-bit numeric address
written as four numbers separated by periods. Each
number can be zero to 255. For example,
190.200.128.111 could be an IP address. Within an
isolated network, you can assign IP addresses at
random if each one is unique. Connecting a private
network to the Internet requires using registered IP
addresses (called Internet addresses) to avoid
duplicates.

4.4 Using ARP.EXE to Assign an Initial IP
Address
Read this entire section before assigning
an initial IP address.
Ensure that power is applied to the C900TTL-E, and
the Ethernet Network RJ45 connection is in place.
The C900TTL-E to be configured and the
configuring PC must be on the same
gateway (the device that connects the LAN
to the WAN). The gateway can be called a
router or hub.
After the C900TTL-E is configured and has
an IP address, you can communicate
changing configuration parameters from
anywhere on the network.
After you have the IP address and the network
administrator confirms that the network is ready, open
the MS-DOSprompt (from Windows) on any PC
connected to the network that is to be used. You now
need to use the ARP command to assign the new IP
address for the C900TTL-E.
ARP is a program used to associate the C900TTL-E IP
address with its MAC address temporarily. The ARP
program is placed in the C:/WINDOWS directory by
default in Microsoft®Windows®98, Windows NT®,
Windows®2000, Windows®XP and Windows®ME
during installation.
Use the command syntax shown in Figure 12 at the
MS-DOS®prompt (usually C:\windows or
C:\WINNT).
Figure 12: ARP Syntax
arp –s xxx.xxx.xxx.xxx zz-zz-zz-zz-zz-zz
xxx.xxx.xxx.xxx
is the IP address assigned
to the D9133TTL-E Serial
Interface by the Network
Administrator
zz-zz-zz-zz-zz-zz
is the MAC hardware
address found on the
label of the D9133TTL-E
Serial Interface.
The IP and MAC address used in this
example are not the same as the numbers
you are using. This is for demonstration
purposes only!
4.4.1 ARP Command Usage
The following procedure details the assignment of an
IP address to a C900TTL-E, using the ARP command:
1. Select Start → Run to open a DOS window.
2. At the Run dialog box, type COMMAND and
click OK.
A DOS window appears:
3. At the DOS command line type: arp –s
172.17.10.70 00-20-4a-12-04-0e and
press the [ENTER] key.
If the computer responds with a C:\WINDOWS
prompt after your command, the address was
accepted.
There is no indication that the operation
was performed properly. The absence of an
error message is the only indication that the
function was correct.
4. To verify the IP address was entered correctly into
the ARP table, type: arp -g and press the
[ENTER] key.
The Internet address (IP address) and the
corresponding Physical Address (MAC hardware
address) appear. The third line of the table in
Figure 13 shows that the ARP table contains MAC
address 00-20-4a-51-19-8c, temporarily linked to IP
address 172.17.10.70.
The network uses this table to identify devices and
to route signals. The number of devices and other
signals (such as “dynamic”) depend on the network
and the number and type of devices with which
this PC has communicated.
5. Identify the MAC address of the device you are
installing and verify that it now has a linked IP
address.
