5.3.7 background communication setup
Background communication setup includes setting up the communication
mode(MODEM or RS232) , baud rate selection(9600, 4800, 2400 and 1200), call-
back times(1-5 times), as shown in Figure 5-34.
Pressing F4(modification key) to start setting the background communication mode,
pressing F2 (move left) and F3 (move right) to move the cursor to the expected
value, and pressing F4(Enter key) to confirm. If you do not want to modify the
parameters, pressing F1(ESC) to escape.
The setting method of baud rate is the same with above.
The call-back times setup means that when the UPS has a fault, the UPS can call
the number in preset times(if it is set to 5, then call 5 times) through MODEM
automatically. Pressing F4(modifying key) to enter the menu of setting call-back
times, pressing F2 (move left) and F3 (move right) to change the times. Pressing
F4 to store the changed parameter and exit.
After setting the above three parameters, pressing F3 (down) to select the last
three items to be set.
