Firmware line LK3.0 LK3.5 LK3.9

1 - For Modbus, HW 3.6 uses different pins (UART_TX and UART_RX in IDC10-1 slot) than HW 3.7+ (GPIO1 and GPIO2 in IDC10-1). Our Modbus converters are designed for HW 3.7+ and cannot be used directly with HW 3.6, but can be used indirectly after rerouting the mentioned pins.

LK3.9 uses DHCP to obtain an IP address by default. It will try to do so for up to 45 seconds after booting. Afterward, it will switch to the static address 192.168.1.100 and use it until the next restart.
