Commands To and From the MKP

0x10 - Connection

During start-up and during changes to the IP Link, this message is sent automatically.
The message is sent over the serial interface, even if the UART has not been enabled (0x23, byte 15 bit 6). It is also sent over Ethernet using the broadcast address (i.e., 192.168.1.255), if an IP Link has been established.
During power down the MKP will attempt to send this message before the power is lost.
The MAC address is included to be able to identify the sending unit in a multi-unit network.
To send a Connection command to the MKP, send ONLY the 2 first bytes. The MKP will respond with the full message.

0x11 - EEPROM Info

This message is sent in response to a client’s Query EEPROM Info command.
This message contains the EEPROM configuration information, including IP address (zeros in all octets indicates the simMKP will acquire an address through DHCP), port (all zeros indicate the simMKP will use the default port), MAC address, and transmit/display options.
See 0x23 – Set Transmit Mode for explanations of the individual fields.

0x23 - Set Transmit Mode

This command sets the transmit and display modes of the MKP.
The MKP will always transmit the current state on the active communication channel in response to a client request. Any response to a received command will be sent back to the same IP address or to the serial interface. However, if Real-time and Periodic reporting is set, it reports to the “Reporting IP address”. This address can be the same or different than the active communication channel.
The MKP will transmit changes in real-time and will transmit the state on a periodic basis (1 second intervals). This behavior can be inhibited by setting bits 0 and 1 in byte 3.
Optionally, the MKP can be configured to broadcast real-time changes and periodic state reports to the IP broadcast address. This behavior can be enabled by setting bits 4 and 5 in byte 3.
All mode configurations are saved in EEPROM and will resume immediately at start-up.

0x24 - Get Status Mode
1. The simMKP will report the different states checked in command 0x23 byte 4. If nothing is selected, the Button/Switch state is reported (0x14).
2. The generated report will be sent back to where 0x24 was received from. The report is not sent to the Reporting IP address set in 0x23.

0x25 - Set Remote Button

A button can be pushed remotely from the controlling client. This command will instruct the simMKP to push the indicated button.
Only send one button push at a time. The simMKP will only push the first button found in the packet.
