Command Manual

WIZ510SSL Command Overview#

WIZ510SSL provides various commands for the product’s setting and control. Each command is composed of a 2 byte alphabet character strings and all capital letters. By using these commands users can add script to the serial device or main MCU for product settings, and also can create a program[1] for controlling the WIZ510SSL module via network.

Each command can operate read/write depending on the parameter, and there is also a read only command[2].

Entering the command and switching the command mode of the serial port device is done using the data UART port. The debug UART port is not supported for command entering or operation.

Identical 2-byte character strings is used for setting the product with commands via serial and Ethernet network, but there will a distinction of the sending frame form. Thus this document will cover explanations of all commands and guides for each sending methods and its form of frames.

The different command modes are as following.

  1. The Configuration tool provided by WIZnet uses the identical command set to control WIZ510SSL.

  2. For example, when the MC command for checking the MAC address and the VR command for checking the firmware are identical.

Usage of Command Set#

Entering Serial Command Mode#

You can use either of the two methods below to enter serial command mode.

1. Enter command mode using hardware trigger pin

  • Use the HW_TRIG pin of the WIZ510SSL (For the EVB, HW_TRIG switch) to enter command mode.
  • Upon turning the power on, check the pin to enter command mode. Use the trigger pin to re-enter the command mode when rebooting.
  • The trigger pin should be pull-up, and operates as low active.
  • This method is used when users wish to change settings while the product operation is initiated.
  - Set the hardware trigger pin(HW_TRIG) to Low.     · When using the EVB, place the HW_TRIG switch to Command.
  - Power on the WIZ510SSL.     · When operating in serial command mode, users can check the following message via Debug UART port.     · <code>> SEG:AT Mode </code>  - Enter the Command and Parameter that needs setting via serial port((Data UART port)).
  - Switch to data transmission mode(GW mode) using [[#ex|EX]] command.     · If the switch to data transmission mode is successful, users can check the following message via Debug UART port.     · <code>> SEG:GW Mode </code>

2. Enter command mode using command mode switch code[1]

  • Users can enter command mode using the command mode switch code provided by WIZ510SSL.
  • The command mode switch codes can be used only if it is enabled in the configuration tool. (default: Enabled)
  • The command mode switch code is composed of 3-byte Hex codes, and can be changed to a different value if needed. The code only accepts Hex value. (default: Hex [2B][2B][2B][2])
  - Check if 'Serial command mode switch code' is enabled at the configuration tool and the 3-bytes 'command mode switch code'.
  - Enter the ‘command mode switch code’ via data UART port to change modes.    · Read below what you need to be cautious about when switching to command mode.    · When operating in serial command mode, users can check the following message via Debug UART port.    · <code>> SEG:AT Mode </code>
  - Enter the Command and Parameter that needs setting via serial port.
  - Use [[#ex|EX]] command to switch to data transmission mode.    · When operating in data transmission mode, users can check the following message via Debug UART port.    · <code>> SEG:GW Mode </code>
  1. Command mode switch trigger code via Data UART port

  2. Char '+++'

Please be cautious when using the trigger code to switch command mode.

  - There has to be a time gap of **at least 500ms** at the start and end of the ‘command mode switch code’ in order it to be read as switch code.
  - The entering time in between each byte of the ‘3-byte command mode switch code’ has to be **below 500ms**.
  - Do not add CR or LF at the end of the command mode switch code((Conversely, the serial command after mode switch must end with CR or LF.)).
  - The default values of 1 and 2 above are **500ms**; these values change to the timer value if the timer value of the serial data packing option is set to a certain value.

Serial Command Frame Format#

You must include CR and LF at the end of each command. CR and LF must be included at the end of each commands when multiple commands are entered simultaneously.

Get Request#
[2-bytes Command Code] [CR] [LF]
  • Enter command without parameter.
  • The response relevant to the command will return.
Set Request#
[2-bytes Command Code] [Parameters] [CR] [LF]
  • Enter the command and parameters you wish to set.
  • There will be no particular response and the field value relevant to the command will change instantly.
  • You have to use the SV command in order to save settings, and use the RT command to change IP allocation methods or other initial operation changes.

* Note: You can check the Echoback of UART command via EC command.


Command over Ethernet#

Users can control or monitor WIZ510SSL via Ethernet by using the following commands. The user must use UDP or TCP client [1] to send commands, and the port number for processing the commands is 50001.

Network information for command transmission: UDP / TCP Server : 50001 (User can send the commands by UDP / TCP Client to device)

Ethernet Command Frame Format#

Two additional commands are required before sending the command code when controlling the WIZ510SSL via Ethernet. All other settings and operations are the same as when sending the serial command code via data UART port.

The two additional commands are MA and PW.

  • [MA] command

    • This field shows the product’s MAC address.
    • In both cases of TCP and UDP, 6-byte MAC address must be included after the 2-byte MA command.
      • When users wish to broadcast only Get Request via UDP[2], the relevant field value can be set as the Broadcast MAC address[3]. Users can receive responses from multiple peers. The search function of the configuration tool is implemented like this
  • [PW] command

  1. Users must use UDP or TCP client because the UDP or TCP server is operating to handle the device commands.

  2. Data is sent to the broadcast IP address 255.255.255.255, and data can be sent to all peers in the same network.

  3. FF:FF:FF:FF:FF:FF

  4. Hex 0x20 is ASCII code, which means blank.

Get Request#

When sending a single command

MA [MAC] [CR] [LF] PW [Search ID] [CR] [LF] [Command] [CR] [LF]

When sending multiple commands

MA [MAC] [CR] [LF] PW [Search ID] [CR] [LF] ([Command] [CR] [LF]) * Number of commands
  • The response for ‘get request’ will have the identical format as ‘request’ but include the parameter[1].
Set Request#

When sending a single command

MA [MAC] [CR] [LF] PW [Search ID] [CR] [LF] [Command] [Parameters] [CR] [LF]

When sending multiple commands

MA [MAC] [CR] [LF] PW [Search ID] [CR] [LF] ([Command] [Parameters] [CR] [LF]) * Number of commands
  • For ‘Set Request’, there is no additional response needed for changing the product setting.
  • If users want to check the modified setting, send the command without parameter at the end of the ‘Set Request frame’; in form of Set + Get Request.
