Modem configuration

Before connecting a modem to the controller’s RS-232 port (marked “CONFIGURATION”), the modem must be configured with the following settings:

•Baud Rate = 9600, 19200, or 38400 (Must match Baud Rate configured in HC900 Controller)

•Parity = None

•1 stop bit

•8 data bits

•No handshaking

•Ignore DTR

•Suppress result codes

•Suppress echo

•Auto answer

•Disable command recognition (only necessary if the modem has this capability)

Some of these settings may be settable via switches. Others may require command strings to be written to the modem using a PC terminal program such as Hyperterminal. You will need to refer to your modem’s documentation to make this determination. Those settings that are configured using command strings must be saved to the modem’s non-volatile RAM (NVRAM), and the NVRAM must be configured as the profile that gets loaded when the modem is powered up.

Most modems are equipped with auto-recognition to set the baud rate, parity, stop bits, and data bits. If your modem has no means of setting these using switches, then most likely it is equipped with auto- recognition. To configure the port settings of a modem with auto recognition, do the following:

Step

Action

 

 

1Connect the modem to a PC.

2Power up the modem.

3Start up a PC terminal program such as Hyperterminal.

4Configure the PC COM Port for 9600, 19200, or 38400 baud (must match baud rate configured in the HC900 Controller), no parity, 1 stop bit, and 8 data bits.

5Establish communications with the modem. A common way of doing this is simply entering the AT E1 Q0 command and seeing if the modem responds with OK.

Once you establish communication to the modem, its port settings are configured.

6Save the port settings to the profile that gets loaded on power-up.
