SmartPass® Integrated Reader 2450 MHz (High Voltage) System Guide
Testing With a PC and the Software Diskette
Testing SmartPass with a PC and the software diskette verifies that SmartPass
hardware and software are working and that the communications hardware is
operating correctly.
SmartPass can interface with the host computer by using either an RS–232 interface,
an RS–422 interface, or with a Wiegand interface. Refer to the appropriate section
below to connect the interface you are using with your SmartPass. SmartPass does
not need to be powered down before attaching it to the PC. The power-up sequence
does not affect communications between SmartPass and the PC.
Connecting an RS–232 Interface
Follow these instructions if your SmartPass uses an RS–232 interface. RS–232
interface signals are supplied by five wires from the SmartPass communications
cable. The wire connections are shown in Table 3-2.
