SM560SAMAN
DESCRIPTION
The SM560SA is a 56 Kbps dial-up
Modem in a standalone case. It is
completely compatible with other V.34 AT
command set Modems and is designed for
traffic control environments. The
SM560SA has a built in power supply and
plugs into a standard outlet. The
SM560SA-12 connects to a 12VDC
supply. The Black wire from the cord is
connected to +12V and the white wire is
connected to Ground. The SM560SA
comes standard with an RS-232 port that
connects to a Computer or Traffic
controller through a DB-9 (female)
connector on the back panel. The phone
line connects to the SM560SA through a
standard RJ-11 connector. The SM560SA
can not be used with leased lines. A second
RJ-11 connector can be used for a phone
connection.
The SM560SA can operate at 56 Kbps and
automatically fall back all the way down to
300 baud. The Modem speed can also be
set using the AT commands if wanted (see
AT Command listing). The serial port has a
maximum speed of 115.2 Kbps and is RS-
232 and V.24 compatible. An RS-485
option is also available using the same DB-
9 connector.
A speaker is included internal to the
Modem so that call progress can be heard.
The speaker is controlled through standard
AT Commands. Front panel LEDs show
the status of the Modem. The SM560SA
has Auto Answer, Auto Dial, and tone or
pulse dialing. A front panel switch allows
you to set DTR active all the time if DTR
is not available. Front panel dip switches
also allow you to invert the RS-485 data
and control signals if that option is
installed.
