Setting the DIP Switches

DIP Switch settings perform three tasks for the Hand Reader (see Figure 17-11).

Set End of Line (EOL) Termination to match the type of termination the network being

used needs.

• Set the Communication Method to match the type of network used.

• Erase Memory to clear Hand Reader memory to all factory default values and also

clear all user memory.

Refer to Figure 17-2 on page 66 for the location of all DIP switches described in this

section.

If a Hand Reader is used as a stand-alone Hand Reader, the End of Line (EOL)

Termination and Communication Method dip switches are not used and should be left in

their default positions.
