ATO Communication mode activation ‘ATO’ command gives an instant access to
the module’s Operating mode. ‘ATO’ command is used to get out of
Configuration Mode. Answer: Good Bye!
AT/V Register
Handling
Command
‘AT/V’ command displays the module’s firmware version
Ex)
AT/V<CR>
‘S424V1.0’ // LinkWiser-S, 424MHz, V1.0
‘HP915V2.0 // LinkWiser-HP, 915MHz, V2.0
AT/L ‘AT/L’ command displays a dynamic and clear status of all relevant registers of
the module with the following categories: Serial link, Radio, Operation Mode,
Network (for consumers)
AT+I Factory default
Set all registers’ values to factory default ones
12-1-3 Registers Description
The parameters to be configured via Configuration mode are stored in module’s EEPROM’s registers,
called S registers. Those registers are always listed as follows:
The standard registers and their use are shown in the next table.
Access Registers Name Description
R/W ATS102
Serial
FIFO
Time Out
Serial Link
Time Out
Indicates the value of the time-out on the serial link (in
Byte).
Ex): a value ‘3’ means a 3 bytes or milli sec. time out time.
This is used: when the serial FIFO is not full, after this
time out, the data in the FIFO will be sent out via RF link.
Value Range: 3~255, Default: 5
R/W ATS103 * Sleep Mode
Control *
Sleep Mode Control:
0 – Disabled (Default), module always active 1 – Enabled
If S103=1, the module will be controlled by I/O1
I/O1 = 0: Sleep Mode(power down mode)
I/O1 =1: active
R/W ATS104 Serial Baud
Rate
Indicates the serial baud rate with DTE:
'0': 1200 bps
'1': 2400 bps
'2': 4800 bps
'3': 9600 bps (default)
'4': 19200 bps
'5': 38400 bps
R/W ATS120 Network ID Network ID in 2 Bytes. Ex).: ATS120=192.168 will set the
network ID to 192.168
R/W ATS121 Group ID Group ID. All and only devices with the same group id
(together with the network id) will be linkable.
R/W ATS122 Device ID Device ID
Value Range: 1~255, Default: 1
R/W ATS130 Node Type Node Type
‘0’: Normal node (not intent to route a message)
’1’: Repeater node (This is a repeater, and will route any
message it received)
R/W S131 Via Repeater
Link
Via Repeater Link Control
‘0’ : Disabled
