INSTALLATION

CABLE INSTALLATION (INTERFACE SPECIFIC)
Keyboard Wedge
1. Turn off the host system.
2. Disconnect the keyboard from the host.
3. Connect the keyed VLink cable to the 10-pin Multi-Interface jack. It is the only circular keyed jack located on the bottom of the MS7820 (see figure 5).
4. Connect the “Y” end of the VLink cable to the keyboard and the keyboard port on the host. If necessary, use the male/female adapter cable supplied with the scanner for proper connections.
Before continuing, verify the VLink cable is connected to the appropriate interface jack on the scanner. An incorrect cable connection can cause communication problems or potential damage to the scanner.
5. Connect the external power supply to the power jack on the scanner.
6. Check the AC input requirements of the power supply to make sure the voltage matches the AC outlet.
7. Connect AC power to the transformer. The outlet should be near the equipment and easily accessible.
8. Scan the Recall Defaults bar code to configure the MS7820 for Keyboard Wedge communication.
9. Turn on the host system.
10. Snap on the cable cover.

CABLE INSTALLATION (INTERFACE SPECIFIC)
USB
1. Connect the keyed VLink cable to the 10-pin Multi-Interface jack. It is the only circular keyed jack located on the bottom of the MS7820
2. Connect the other end of the USB cable to the host.
Before continuing, verify the USB cable is connected to the appropriate interface jack on the scanner. An incorrect cable connection can cause communication problems or potential damage to the scanner.
3. Scan the Recall Defaults bar code to configure the MS7820 for USB communication.
4. Turn on the host system.
5. Snap on the cable cover.
For additional communication options for USB interfaces refer to the MetroSelect Configuration Guide (MLPN 00-02407).
(see figure 6).
Plugging the scanner into the USB port of the PC does not guarantee that scanned information will appear at the PC. A software driver and correct configuration setting may also be required for proper communication depending on settings.

INSTALLATION
CABLE INSTALLATION (SECONDARY METROLOGIC SCANNER)
1. Turn off the host system.
2. Connect the round end of the VLink RS232 AUX cable [
MLPN 57-57499-3] to the RS232 jack of the auxiliary scanner (see figure 9 on
page 18).
3. Connect the other end of the VLink RS232 AUX cable into the Auxiliary
(AUX) jack, which is located directly next to the circular keyed Multi-Interface jack. The Auxiliary (AUX) jack has a square opening.
The following Metrologic scanners can be used in the Auxiliary (AUX) input of the MS7820: the MS9520, MS9540, MS7120, MS7220 or another MS7820.
Important: The MS7820 aux port requires the signals: transmit, receive,
4. Connect the MS7820/Host VLink* cable to the circular keyed Multi-Interface jack located on the bottom of the MS7820.
5. Connect the other end of the MS7820/Host VLink cable to the Host.
6. Connect the external power supply to the power jack on the VLink cable.
7. Check the AC input requirements of the power supply to make sure the voltage matches the AC outlet.
8. Snap on the cable cover.
9. Connect AC power to the transformer. The outlet should be near the equipment and easily accessible.
10. Configure the MS7820 for the appropriate interface configuration settings.*
* The MS7820/host cable connection is interface dependent. Refer to the
installation steps provided for the type of interface (RS232, IBM 46xx, etc.) required for your application.
