Connecting an RS-232 Interface
This connection is made directly from the cradle to the host computer.
Figure 7-1
RS-232 Direct Connection
To connect the RS-232 interface:
1. Attach the modular connector of the RS-232 interface cable to the host port on the bottom of the scanner
cradle (see Connecting the Cradle on page 1-6).
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 7-6.
5. To modify any other parameter options, scan the appropriate bar codes in this chapter.
NOTE See Chapter 4, Radio Communications for information about scanner/cradle pairing and wireless
communication
The scanner must be connected to the cradle for the host parameter setting to take effect. When the
scanner is not connected to a cradle, and a host parameter bar code is scanned, a long low/long high
beep sequence sounds.
