Modem Settings
A DM-100 controller can be connected to a modem, allowing for control of a
DataMaster display remotely via a telephone network.
The first time a modem system is used, modem settings (such as Dial-Out Number)
must be programmed into the DM-100.
When a modem is detected and all configurations have been set, pressing the
<
DISPLAY SEQUENCE > key will show the following:
If more than one modem dial number is configured, the DM-100 will ask which
displays to update before dialing.
The modem will dial the number shown on the bottom line of the LCD. When
complete, the modem will send the sequence to the display and wait for a response.
The result will be shown on the LCD.
To cancel connection to the display, press the <
CLEAR > key twice.
If the modem is not able to connect to the display, a modem error message will be
displayed.
When the modem is connected to the display, a "C" character will flash on the lower
right corner of the LCD to show that a modem connection has been established.
