RS-232 Interface 6-3
Introduction
This chapter describes how to set up the scanner with an RS-232 host. The RS-232 interface is used to connect the scanner to point-
of-sale devices, host computers, or other devices with an available RS-232 port (e.g., com port).
If the host is not listed in Table 6-2, refer to the documentation for the host device to set communication parameters to match the host.
The scanner uses TTL RS-232 signal levels, which interface with most system architectures. For system
architectures requiring RS-232C signal levels, Symbol offers different cables providing TTL-to-RS-232C
conversion. Contact the Symbol Global Customer Interaction Center for more information.
Throughout the programming bar code menus, default values are indicated with asterisks (*).
Connecting an RS-232 Interface
This connection is made directly from the scanner to the host computer.

Figure 6-1. RS-232 Direct Connection

Interface cables vary depending on configuration. The connectors illustrated in Figure 6-1 are examples only.
The connectors may be different than those illustrated, but the steps to connect the scanner remain the same.
1. Attach the modular connector of the RS-232 interface cable to the cable interface port on the scanner (see Installing the
Interface Cable on page 1-4).
2. Connect the other end of the RS-232 interface cable to the serial port on the host.
3. Connect the power supply to the serial connector end of the RS-232 interface cable. Plug the power supply into an
appropriate outlet.
4. Select the RS-232 host type by scanning the appropriate bar code from RS-232 Host Types on page 6-7.
5. To modify any other parameter options, scan the appropriate bar codes in this chapter.
