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 RS­232 and V.24 compatible. An RS-485 option is also available using the same DB­9 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.

Th SM560SA can store 2 user profiles and 4 phone numbers. The numbers can have up to 32 digits.
INSTALLATION
The SM560SA comes from the factory set up for 90 to 130 VAC. If 180 to 260 VAC operation is required, the Zero Ohm jumpers labeled “110VAC” (R8 and R9) should be removed and the Zero Ohm Jumper labeled “220VAC” (R10) installed. These jumpers are located between the transformer and the fuse on the PC Board.
The SM560SA-12 connects to a 12 Volt DC supply rated at least to 0.5A. The Black wire connects to +12V and the white wire connects to Ground. The green wire is Chassis Gnd.

The Phone line is connected to the RJ11 connector on the back panel labeled “LINE”. An exterior phone can be connected to the RJ11 labeled “PHONE”. The RJ11 connectors are connected in parallel so do not use the phone while the modem is being used.
RJ11 PIN-OUT
2 TIP 3 RING
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.
A special cable will be needed if you have the RS-485 option since there is no standard pin-out for RS-485 with this connector. The DB-9 is pinned out according to the way CALTRANS has defined it on the 2070-7.
The connection chart for a 170 type controller is shown below:
170 Connection Chart
Function DB-9 170 C2,20 TXD 3 K 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. DTR can be permanently
asserted with the front panel switch if you don’t want to use the AT command.
485 OPTION
The SM560SA has the 120-Ohm termination resistors built into the unit on the input lines (TXD and RTS). This Modem is not designed to be used in an RS-485 Multi-drop system.
The polarity of theRS-485 signals can be inverted if needed by two front panel dip switches. The Switch labeled “DATA” will invert the TXD and RXD signals and the Switch labeled “CTR” will invert the RTS and CTS signals. These Switches have no affect on RS-232 operation.
Indicators
The Indicators on the front panel give the status of the SM560SA.
POWER………Indicates that the Power Supply is operating.
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 are no adjustments or user selectable features inside the Modem. There is no preventative maintenance required or anything that needs to be adjusted for the life of the product.
The following pages contain a summary of the AT Commands and “S” Registers that the SM560SA 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.
