Initialization JSD DA-A02 modules:
All JSD DA-A02 modules, if you use RS-485 network, must be assigned a unique address code, address code value of hexadecimal numbers between 00 and FF. However, all new JSD DA-A02 modules use one factory initial settings, as follows:
Address code: 01
Baud rate: 9600 bps
Checksum is forbidden
As the new module address codes are the same, their address will be contradictory to other modules, so when you set up the system, you must reconfigure each JSD DA-A02 module address. JSD DA-A02 module can be connected the power cord and RS485 communication lines, through configuration commands to modify the JSD DA-A02 module address. Baud rate, parity and status, communication protocols also need to be adjusted according to user requirements. In the modified baud rate, parity and status, communication protocol, you must first enter the module to the default state, or can't be modified.
Let the module into the default state:
JSD DA-A02 module has a special INIT pin. Connecting the INIT PIN to ground (GND PIN), then open power, the module into the default state. In this state, the module is configured as follows:
Address code 00
9600 bps baud rate
Checksum is forbidden, At this time, via configuration commands you can modify the JSD DA-A02 module baud rate, parity, checksum state and other parameters, by setting the module communication protocol command to select the communication protocol. When are not sure a module specific configuration, can also be configured by installing the jumper, so that the module into the default state, then reconfigure the module. If clients need set the module to MODBUS RTU communication protocol, see the MODBUS protocol section for instructions.
JSD DA-A02 character protocol command set:
Order is by a series of characters, such as first code, address ID, variables, an optional checksum byte and a terminator (c r) which can show command. In addition to wildcard address "**"synchronization command, the host only commands a JSD DA-A02 module once.
Command format: (Leading Code) (Addr) (Command) [data] [checksum] (c r)
(Leading code) prefix is the first letter of the command. All commands require a command prefix, such as %,$,#,@,...
etc. 1 - Character
( Addr ) module address code, if not specified below, range is from 00 ~ FF (hexadecimal). 2 - Character
(Command) shows the command code or variable values. Variable length
[Data] some output command needs data Variable length
[Checksum] brackets Checksum (checksum) shows an optional parameter, only the checksum is enabled, need this option. 2 - Character (Cr) a control code character as identify, (c r) as a carriage return character, its value is 0x0D. 1 - Character When enabled checksum (checksum), users need [Checksum]. It accounted for 2 - character. Commands and responses must be attached checksum feature. Checksum used to check all input commands to help you find the host to the module command module to the host response to errors and mistakes. Checksum characters placed in command or in response to the character after the carriage return before. Calculated as follows: two characters, the hexadecimal number for all issued prior to the ASCII values of and, then with hexadecimal digits 0xFF phase proceeds.
Examples: Disable checksum (checksum)
Command: $002(cr)
Response:!00020600 (cr)
Enable checksum
command: $002B6 (cr)
response: !00020600 A9 (cr)
'$' = 0x24 '0' = 0x30 '2' = 0x32
B6=(0x24+0x30+0x30+0x32) AND 0xFF
'!' = 0x21 '0' = 0x30 '2' = 0x32 '6' = 0x36
A9=(0x21+0x30+0x30+0x30+0x32+0x30+0x36+0x30+0x30) AND 0xFF
Command response:
Response message depends on a variety of commands. Response also is consists of several characters, includes
leading code, variables and end tags. The first code of response signal has two:'!' Or '>' indicates that a valid command
and '?' means invalid. By checking the response information, you can monitor whether the command is valid
Note:
1. In some cases, many commands use the same command format. To ensure that you use a command in the address is correct, if you use the wrong address and this address represents another module, then the command will take effect
in another module, resulting in an error.
