S
w##
This command writes a register in binary format. The first byte following the “w” is the address in binary format
and the second byte is the data in binary format. This is a faster method to write registers than the “SR=N”
command and is recommended for use by a host controller.
r#
This command reads a register in binary format. The byte following the “r” is the address in binary format.
The modem returns the contents of this register in binary format. This is a faster method to read registers than
the “SR?” command and is recommended for use by a host controller.
rm#
This command monitors a register in binary format. The byte following the “m” is the address in binary. The
CC-2401 constantly transmits the contents of the register at the set baud rate until a new byte is transmitted to
the device. The new byte is ignored and viewed as a stop c ommand. The modem result codes should be
disabled before using this command.
q#
This command is the same as the r# command. The response from the CC-2401 is formatted as 0x55
followed by the contents of the register in binary. This guarantees that the register contents are always
preceded by 0x66 and allows the result codes to remain enabled.
V
Z
This command initiates a software reset causing all registers, except E0 to default to their powerup value.
z
The CC-2401 enters a low power mode. In this mode, only the line side of the modem is functional. An
incoming ring signal or line transient causes the modem to power up and send a “R” to the UART. Any other
character received on the RXD pin also causes the modem to exit the wakeup on ring state. Return from wake
on ring cal also be set to trigger the INT# pin by setting S08[6] (WORM) = 1.
Alarm Industry AT Commands
The CC-2401 supports a complete set of commands necessary for making connections in security industry
systems. The CC-2401 is configurable in two modes for these applications. The first mode uses DTMF
messaging and is selected with the “!1” command. The second mode uses FSK transmit with a tone
acknowledgement and is selected by “!2”.
The following are a few general comments about the use of “!” commands. Specific details for each command
are given below. The first instance of the “!” must be on the same line as the ATDT or ATDP command. DRT
must be set to data mode (SE4[5:4](DRT) = 0
three data-mode escape sequence (“+++”, “escape” pin and “ninth-bit”) only function in “!2” mode. However,
SR=N
Writes an S-register. This command writes the value “N” to the S-register specified by “R”. “R” is a
hexadecimal number and “N” must also be a hexadecimal number from 00-FF. This command does not
wait for a carriage return <CR> before taking effect. Two digits must always be entered for both “R” and
“N”.
SR?
Read an S-register. This command causes the CC-2401 to return the value of the S-register specified by
R in hex format. R must be a hexadecimal number. Two digits must always be entered for “R”.
V0
Result codes reported according to Table 14. <SC>
V1
Result codes reported with an additional carriage return and line feeds (default).
