SWB6:
Factory set to OFF (for the most reliable operation should not be changed). Reader will read
upon insertion and withdrawal. If set to the ON position, the Reader will read on Insert only.
Data is transmitted upon contact of the rear sensor.
SWB7:
Set to the ON position to jumper the control signals RTS-CTS. Set to OFF is these signals are
implemented by the Host.
SWB8:
Set to the ON position to jumper the control signals DSR-DTR. Set to OFF is these signals are
implemented by the Host.
Notes:
1. In previous versions of the Reader, a switch was used to enable reading either a 5-bit
data format or a 7-bit data format. In this version the function of reading a 7- or 5-bit
format is performed automatically by the firmware.
2. Switches that are factory set must be set in the position indicated when used by the
customer. The Reader is one of a series of products using the same microcontroller. The
factory set switches make the microcontroller function properly in the Reader.
