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.
NOTE
: Please note that device is recommended with true hardware RS232 ports.The use of virtualized serial ports may cause technical
problems.

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.
