Host Interface
Line Interface
© 2007, Copeland Communications, Inc.
The host interface is serial TTL. The default host speed of 2400 baud and 8N1 format (8 data bits, no parity bit
and 1 stop bit). The defaults can be changes after initialization by using standard AT commands. A true RS-
232 interface is available on the World modem Evaluation Board.
To change the serial baud rate, the command ATSE0=xxx where xxx is (a carriage return must follow every
command for it to be effected):
As soon as the command is issued, the host must change its baud rate to match the World Modem II’s new
data rate.
The CC-2401 can be configured to any of the Bell and CCITT operation modes listed in table <SC>. In
V.22bis, the modem connects at 1200 bps if the other modem is configured for V.22. The CC-2401 also
supports S1A and other protocols for the security industry.
configurations.
The CC-2401 does not continuously check for stop bits on the incoming digital data. If the TXD pin is not high,
the RXD pin may echo meaningless characters to the host. This requires the UART to flush its receiver FIFO
upon initialization.
