GENERAL DESCRIPTION
The SM336 is a 33.6 Kbps dial-up modem in a
Model 400 form factor designed for use in a
Model 170 Controller.
It is completely compatible with other V.34 AT
command set modems and is specifically
designed for traffic control environments.
The SM336 is supplied with an RS-232 port that
can connect to a computer through a female DB-
9 connector located on the front of the card.
The phone line connects to the SM336 through a
standard RJ-11 connector. A second RJ-11
connector can be used to connect a telephone.
The SM336 can operate up to 33.6 Kbps and
automatically fall back to data rates as low as
300 baud.
All modem parameters such as speed, etc., can
be set and controlled using the industry standard
AT command set (see AT Command summary
beginning on page 6).
The serial port has a maximum speed of 115.2
Kbps and is RS-232 and V.24 compatible.
The SM336 cannot be used with leased lines.
Indicators on the front of the card show the
status of the modem, and include TXD, RXD,
DCD, DTR, DSR, and RI.
The SM336 also features Auto Answer, Auto
Dial, and tone or pulse dialing.

INDICATORS

The SM336 can store 2 user profiles and 4 phone
numbers. The numbers can have up to 32 digits.
INSTALLATION
The SM336 receives power from the Model 170
Controller, and the Controller should always be
powered down, or OFF for a minute or so before
inserting the SM336 into the card frame. This
should allow ample time for potentially
damaging power supply voltages to dissipate.
The incoming phone line is to be connected to
the RJ-11 connector labeled “LINE”. An external
phone can be connected to the RJ-11 labeled
“PHONE”.
Note: As the RJ11 connectors are connected in
parallel, remember not to use the phone while
the modem is in operation.

SM336 Manual 3
The DB-9 connector is pinned out so that a one-
to-one cable is needed to connect to most
computers. Since most computers use a DB-9
connector with male pins, the cable will need to
have one female and one male connector on it.
The connection chart for a 170 type controller is
shown below:

Function DB-9 170 C2,20
TXD 3

RXD 2 L
RTS 7 J
CTS 8 M
DCD 1 H
GND 5 N
As can be seen from the Chart, the 170 doesn’t
use DTR and DSR. DTR can be set up to be
ignored by the Modem with an AT command, as
shown in the AT command summary below.
Indicators
Indicators on the front of the card give the status
of the SM336.
TXD…………Indicates that data is being
Transmitted
RXD………….Indicates that data is being
Received
DTR……….. Indicates that Data terminal
Ready is true.
DSR (OH)…..Indicates that Data SET
Ready is true. It is also
An indicator of the OFF
Hook condition.
DCD…………Indicates that the modem
Is detecting a carrier.
RI……………Indicates that the Modem is
Receiving a Ring signal.
There is no preventative maintenance required or
anything that needs to be adjusted for the life of
the product.
Switch settings:
Port B is ACIA 2 or 4 and Port A is ACIA 1 or 3 in the 170 Controller.

Note: To configure the smart modem section using the DB-9, SW2 and SW3 should both be in the
OFF position to avoid interference with Controller data. Once configured, then either Port A or Port
B should be selected via the switches. Port A should be On for the first ACIA Port and Port B should
be On for the ACIA 2. The locations of the switches are shown below.
The following pages contain a summary of the AT Commands and “S” Registers that the SM336
responds to. The factory default settings are also shown. A complete definition of the AT commands is
too large for this Manual (174 pages). If one is required, a PDF file (450K) can be sent electronically to
you.
