Abstract

An apparatus includes a PS2 input for receiving first input logic signals from a first device. A USB input receives second input logic signals from a second device. A RS232 input receives third input logic signals from a third device. A TTL input receives fourth input logic signals from a fourth device. A programmed logic circuit translates the first input logic signals, the second input logic signals, the third input logic signals and the fourth input logic signals to first output logic signals having a RS232 output. The programmed logic circuit further translates the first input logic signals, the second input logic signals, the third input logic signals and the fourth input logic signals to second output logic signals having a TTL output. A RS232 output transmits the first output logic signals to a POS device and a TTL output transmits the second output logic signals to a POS device. Input Ports for logic signals may be distinct in cases where a signal translation function is sought. Input Ports for logic signals may also be repeated for the same input logic where an expansion function is sought.
