Communication Interfaces
The LV4200 can communicate with the host device via its TTL-232 interface. This Interface is applicable to most system architecture. For those requiring RS-232, a TTL-232 to RS-232 conversion circuit is needed.
The LV4200’s TTL-232 interface supports baud rates from 1200 bps to 115200 bps. It does not support hardware flow control its default settings are 96000 bps, 8 data bits, no parity check and 1 stop bit.
Besides, the LV1200 can also communicate with the host device via its USB interface ( optional )
A. USB HID-KBW : Based on USB connection, the engine’s translation is simulated as USB keyboard input. It works on a plug and pay basis and no driver is required;
B. USB COM Port Emulation : THe USB Interface on the host device is emulated as a serial port with the same data transmission and configuration as a real serial port. A driver is required.
C. USB HID-POS : It is based on HID with no need for custom driver and is way more efficient in communication than keyboard emulation and traditional RS-232 interface.
