Product Description
The LAVA POS Serial Port Splitter is an RS-232 device that sends two serial streams to one serial port.The POS Serial Port Splitter is a passive device that attaches to a controlling machine such as a Point of Sale station (POS), computer, or server and then allows up to two input devices such as RFID scanners, bar code readers, mag stripe units, key pads, or any serial input device to be interconnected.Semiconductor circuits are utilized to provide isolation of the prime signals in the RS­232 interface. LAVA supports TX,RX, and GRD to pass the data between the inputting device and the receiving device.This is a elegant device that solves a common problem in today's IT environment and is simple and quick to install.

Data from P1 is
sent to "P2 and P3"
Data from P2 or P3
is sent to P1
POS expects to see data from some device, at a given time. If the data is not as expected, then the application program in the POS rejects the data.
P1 and P2 are "Party-line/multi-dropped" on the RS-232 COM port of the POS.
