3 Auto-Answer Feature

This feature enables the MDR220A unit to answer an incoming call over the phone line. In order to enable this feature, the HyperTerminal program must be opened. HyperTerminal is launched by clicking on the Start icon in Windows and selecting Programs. From the Programs list select Accessories, Communications, then HyperTerminal. Once in HyperTerminal, you must type a name for the connection and click OK. Next to the Connect Using field, select the proper COM Port. Make sure the Baud Rate setting is equal to the MDR221A's Baud Rate setting, Data Bits equals 8, Parity equals None, Stop Bits Equals 1, and Flow Control equals Hardware. Apply the settings and HyperTerminal is ready to send commands.

MDRA220A configuration: Broadcast, Modem Control and RTS should be enabled. MDR221A should be configured with default values and Auto Destination enabled.

Make sure Auto-Answer is enabled on the MDR220A: (Refer to RC56D ATCRM.PDF for the AT Commands)

1)Enable Auto-Answer on the MDR220A

a.Connect the MDR221A to a computer and start HyperTerminal.

b.Type the characters ATS0 = n command, where n = the number of rings to Auto-Answer.

This command sets the S0 parameter to a value other than zero to enable Auto-Answer. S0 sets the number of rings required before the modem automatically answers a call. Setting this parameter to zero disables auto-answer mode.

2)Enable DTR On

a.Send the AT&D0 command

3)Save the Auto-Answer configuration to a modem Profile, 0 or 1.

a.Send the AT&Wn command, where n = Profile number.

The MDRA220A is now ready to answer a phone call automatically.
