Setting Up the Reader/PC Connection
To connect the Reader to a PC, do the following:
1. Use the RS232 or RS485 communication line to connect the Reader to the PC. For more
information on these communication lines, see Connecting the RS232 Communication Line,
and Connecting the RS485 Four-Wire Communication Line in Chapter 2.
For the initial set-up, Lyngsoe recommends using the RS232 connection with a local, mobile PC
(Laptop), as shown in Figure 5-1 below.
