300 Starting Two-way RS232 Communication
You can set up two-way (full-duplex) communication with the Fortress using a dumb terminal or terminal communication program. Two-way communication allows you to issue commands to the Fortress and to display information on your computer or terminal's screen. The commands are in Section 400. To set up two-way communication, follow these steps:
1. Order an interface cable from Best Power (or call Best Power for cable specifications). Connect this cable to the UPS and to the terminal. (Instead of a terminal, you can use a computer with terminal emulation software such as CROSSTALK' or Procomm-, or the Windows Terminal function.) If you are using a terminal, note that Fortress supports the Televideo 900 series, ADM3A and WSE 50 emulation.
Note: If you are connecting the Fortress to a modem, you must configure the modem properly. Set
up the modem to ignore RTS and CTS signals (disable hardware handshaking). Enable sup
port for X/ON X/OFF software handshaking. At the Fortress, parameters 73 and 74 enable
software handshaking; unless you have changed the settings of these parameters, Fortress is
already set up for software handshaking.
2. Start the terminal or run terminal emulation software on your computer.
3. Set the ten-ninal or terminal emulation software for the following:
• FULL DUPLEX • 1200 baud (see note in step 4) • 8 data bits and 1 stop bit • No parity
4. Press <ENTER> at your keyboard. You should receive a => prompt. Press <ENTER> a few times to make sure the Fortress responds.
Note: If you want to change the baud rate at which the Fortress communicates, follow these steps:
a. Set your computer or terminal baud rate to 1200 temporarily so you can communicate with the Fortress.
b. Find the DIP switches on the back of the Fortress; then, find DIP switch 1.
c. If DIP switch I is set to the right, the Fortress baud rate will stay 1200 until you change the DIP switch setting. If DIP switch I is set to the left as it is in the drawing, the Fortress baud rate depends on the setting of parameter 70. When the Fortress is shipped, parameter 70 is also set to 1200. To change the DIP switch setting, use a nonmetal object such as a toothpick to move DIP switch I from one side to the other; if the UPS is on, it will beep. Make sure you do not accidentally change the position of another DIP switch.
d. Establish communication with the Fortress. Then, enter the Service password by typing password 2639 <ENTER>.
e. To display baud rate (parameter 70), type display 70 <ENTER>. If you have never changed the parameter setting, the display will show "70 Baud 2)1200." Setting 0 300, 1 = 600, and 2 = 1200.
f. To change the setting type program 70 <new setting> <ENTER>. Example: To change the baud rate to 300, type program 70 0 <ENTER>.
g. Clear the password by typing clearpassword <ENTER>.
5. To control or monitor the Fortress, simply type the command you need and press <ENTER>. (See Section 402 for a list of commands.) You can use the following keystrokes as you type commands or view displays:
