Emergency Alert System Software for the Sage EndecTM
EASAnywhere was designed to specifically control the Sage Endec. EASAnywhere emulates the front control panel of the Sage Endec so that you may remotely view the Sage Endec display and remotely access its menu.
Connection to the Sage Endec may be through a simple serial port connecton consisting of three wires: send, receive and ground. This is useful for a distance of about 50 feet. Longer distances may need to employ signal conditioning devices connected to the computer and the Sage Endec.
EasAnywhere can be used by a telephone connection using a modem connected to the computer and another modem connected to the Sage Endec. Note: Since the Sage Endec is continuously transmitting data, a relay must be inserted between the modem and the Sage Endec so that the modem will answer and establish a connection with the remote computer before transmitting data from the Sage Endec.
Installation of EASAnywhere software is simple. Click Setup and follow the prompts. Be sure to create the folder c:\EAS. Be sure to copy the file EAS.rtf to this folder. This is your "help" file.
After the software is installed, run EASAnywhere. The first thing you must do is setup the connection. Click "MyConnection". Select the ComPort, BaudRate and select the type of connection. If you have chosen a "dial-up" connection enter the telephone number. Be sure to "Apply" before closing.
Be sure the baud rate matches the rate on the Sage Endec port to which you are connecting.
If you have chosen the serial connection you are ready to begin using EASAnywhere. The Sage display should now be displayed on your computer. If you have chosen "dial connection" dial the number of the remote modem connected to the Sage Endec.
The top row of four buttons correspond to the 4 buttons on the Sage Endec.
The bottom row of four buttons are "shortcuts" to functions. Hme takes the display to Home. Cue plays stored audio. The audio will not be heard at the computer unless a separate connection between the Sage Endec and a local speaker is made. However, the feature is useful since the Sage Endec displays a countdown of any recorded audio. Rec is a record button. Audio via a microphone which must be connected via a separate audio path may be recorded by clicking the Rec button.
Abt is abort and will abort a command.
It is possible to print an EAS log on a printer connected to the computer by clicking "Files" and then "Print EAS Log."

Note: To connect a computer directly to the Sage Endec, use a "null" modem which you may purchase at a computer store or construct yourself. A "null" modem is a cable with the appropriate connectors on each end with some of the connections reversed. To construct a "null" modem for this application use a two conductor shielded cable such as Belden 8451. If the computer has a 9 pin connector connect the shield to pin 5 on each connector. Connect one of the wires in the cable to pin 2 on one connector and pin 3 on the other. Connect the remaining wire from pin 3 to pin 2. If the computer has a 25 pin connector, connect pin 7 of the 25 pin connector to pin 5 of the 9 pin connector. Connect pin 2 of the 25 pin connector to pin 2 of the 9 pin connector and pin 3 of the 25 pin connector to pin 3 of the 9 pin connector.
For using via a dial-up telephone line you will need to connect an "external" modem to a phone line and to the serial port of the Sage Endec. My experience is that you will need to install a relay between the Transmit line and Receive line. Failure to do so may prevent the modem from connecting to the Sage Endec. Route pins two and three through from the Sage Endec to the Modem. If it is a 25 pin connector on the modem connect pin 2 of the Endec to pin 3 of the modem and pin 3 of the Endec to pin 2 of the modem. If the modem uses a 9 pin connector connect... pin 2 to pin 2 and pin 3 to pin 3. Jumper the DSR to the DTR on the modem. Pin 20 to pin 6 on a 25 pin connector or pin 4 to pin 6 on a 9 pin connector.
Obtain a voltage from the DCD, pin 8 on a 25 pin connector and pin 1 on a 9 pin connector and bias a transistor which in turn will drive the relay.
You can use a variety of NPN transistors. Connect a 2700-6800 ohm resistor from the DCD to the base of the transistor. Connect the emitter to ground and the collector to one side of the relay coil, the other side of the coil to B+. It is advisable to place diode across the relay coil to protect the transistor. Be sure the negative end of the diode is connected to the positive side of the coil.
