Note
1.SLCT IN signal can be fixed LOW by setting the printer DIP switch , jumper or SelecType function. If this signal is fixed Low, you should not connect J1. When J1 is ON, SLCT IN signal (pin No. 36 of I/F connector on the I/F board) is connected to the printer through the I/F board to enable it to be controlled by a Host computer. Sampling this signal is always carried out by the printer, therefore this function depends on the printer specification.
2.J2 and J3 jumpers are connected at the factory, and you should not change these setting.
