1. PRODUCT OVERVIEW
The BBI-14.4 is an industrial modem for direct connection to public switched telephone lines.
Though similar to commercial modems, the BBI-14.4 contains special features that make it
particularly well suited for industrial applications. These capabilities include:
Environment The BBI-14.4 has been designed explicitly for use in industrial
environments. In addition to an extended temperature range (-40 to +85oC),
the BBI-14.4 includes surge, shock, vibration, and safety parameters superior
to those of conventional commercial modems.
Low Power The BBI-14.4 implements a "low power" standby mode. This mode allows
the BBI-14.4 to consume a small fraction of its active power while waiting
for either controller or telephone activity.
Industrial The BBI-14.4 uses standard industrial connectors for both data and telephone
interfaces. These connectors allow reliable interconnect to other industrial
components. Furthermore, the BBI-14.4 data lines are provided at either RS-
232 or TTL signal levels for both stand-alone and embedded applications.
2. PRODUCT DESCRIPTION
The BBI-14.4 provides dial-up telephone communication capabilities for the industrial
environment. It can be operated stand-alone or as a component of a larger industrial system.
2.1 Telephone Interface
The BBI-14.4 telephone interface operates over two wire loop start lines available in North
America. The telephone line interface is environmentally benign, allowing use in Class I,
Division 2 applications.
2.2 Data Interface
The BBI-14.4 data interface provides RS-232 compatible serial signaling. The data interface
interconnects to industrial controllers at either RS-232E or TTL signal levels. Selectable RS-
232 only or TTL with RS-232 override
2.3 Power
The BBI-14.4B accepts either regulated 4.75 to 5.25 volts DC, unregulated 5.5 to 7.0 volts
DC (battery) or unregulated 9.5 to 18.0 volt power inputs. The unregulated power inputs are
also suitable for use with 6.0 volt and 12.0 volt solar power systems.
2.4 Mechanical
The BBI-14.4 consists of two printed circuit boards: A single two sided baseboard and a four
layer modem board (Telenetics PE14.4)

4. SERIAL CONNECTOR SPECIFICATIONS
The BBI-14.4 communicates with industrial controllers through RS-232 compatible serial
signaling. Both RS-232E and TTL signal levels are provided. The RS-232E signal levels are
used to interconnect with RS-232E compatible embedded controllers; the TTL signal levels
are used to interconnect with TTL compatible embedded controllers. The RS-232E signal
levels are also used to configure the BBI-14.4.
The RS-232E and TTL signals are present on several connectors. The RS-232 signal levels
are present on three (3) connectors: the TTL levels are present on two (2) connectors;
The BBI-14.4 RS-232E and TTL signals interfaces are independent. All RS-232E signals are
internally connected together; likewise, all TTL signals are internally connected together. The
RS-232E signals, though, are not internally connected to the TTL signals.

4.2 Serial Interface Selection (Jumper J6)
As previously described, the BBI-14.4 has two separate serial interfaces: one for RS-232E
levels and one for TTL levels. BBI-14.4 interface selection is determined either automatically
or manually.
The BBI-14.4 becomes active and responds to a serial interface in response to either the
interface DTR signal becoming active or in response to an incoming ring signal. In the first
case, the interface DTR signal determines the active serial interface. In the second case,
incoming ring, a manual jumper determines the active interface.
When configured to respond to the RS-232E interface (J6 Jumper Position 1-2), an active RS-
232E DTR signal will power up the BBI-14.4 and its RS-232E line drivers. Communication
to and from the BBI-14.4 will be through the RS-232 E serial interface only. The TTL serial
interface signals will be clamped at inactive signal levels. Also in this configuration, when
incoming ring has been detected, the RS-232E interface will become active.
When configured for the TTL interface (J6 Jumper Position 2-3), active TTL DTR signal will
activate the BBI-14.4. Communication is to and from the controller through the TTL serial
interface only. The BBI-14.4 RS-232E line drivers will be powered off. When an incoming
ring has been detected, the TTL interface will become active.
When in the RS-232E configuration, TTL signals are always ignored. This configuration
allows the BBI-14.4A to be used as a conventional modem.
When in the TTL configuration, though, RS-232E signals can be used for BBI-14.4
configuration. Regardless of the state of the TTL serial interface, an active RS-232E DTR
signal will result in inactivating the TWX serial interface, activating the RS-232E serial
interface. If there is an active modem connection the call is not disconnected. To disconnect
the user must enter the command mode (+++) type ATH or drop DTR (to disconnect) and
reinstate DTR to the active state.
The RS-232E configuration is called stand alone mode. It is intended for applications when
attached to intelligent controllers which can configure the BBI-14.4 in the field. The TTL
configuration is called the embedded mode. It is intended for applications when attached to
older controllers that cannot configure the BBI-14.4 in the field. When in embedded mode,
the RS-232E interface is used to configure the BBI-14.4.
Connector Type 3 pin header
Jumper Positions 1-2: RS232 2-3: TTL with RS232 override
NOTE: Section 6 below discusses the BBI-202T's three power supply options and indicates
which serial interface (RS-232 and/or TTL) is supported by each power option.

6.2 Standby Operation
The BBI-14.4 is configured for "low-power" standby operation. When in the standby mode,
the BBI-14.4B consumes only 200uA power. Standby is controlled by the serial interface
(RS-232 or TTL) DTR signal.
The BBI-14.4 will automatically enter standby mode after 30 seconds of no DTR activity.
Standby mode ends when either a ring has been detected on the telephone line or DTR
becomes active. If ringing occurs, the BBI-14.4 increases its power demands only enough to
determine if the ring is valid. If the BBI-14.4 determines the ring invalid, it returns to standby
mode after 30 seconds. If the ring is valid, the BBI-14.4 will answer the call. (Note that the
BBI-14.4B must be in the auto-answer mode, i.e.: S0=1 or greater, see Appendix B)
