INSTALLATION OF AN AUXILIARY SCANNER
1. Turn off the host system.
2. Connect the round end of the PowerLink RS232 AUX cable
[
MLPN 54-54667A ] to the RS232 jack of the auxiliary scanner (see figure 6).
3. Connect the other end of the PowerLink RS232 AUX cable into the 1
st
jack
from the left side of the MS7320. The Aux jack has a square opening.
The following Metrologic scanners can be used in the “Aux” input of the
MS7220: the MS9520, MS9540, MS6220, MS7120, MS6520, MS6720,
MS7320 or another MS7220.
Important: The MS7220 aux port requires the signals: transmit, receive,
RTS & CTS from the auxiliary scanner.
4. Connect the MS7220/Host PowerLink* cable to the appropriate interface
jack on the back of the MS7220.
5. Connect the other end of the MS7220/Host PowerLink cable to the Host.
6. Connect the external power supplies for the auxiliary scanner and the
MS7220 to the power jacks on the two PowerLink cables.
Before continuing verify that the powerlink 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.
7. Check the AC input requirements of both power supplies to make sure the
voltage matches the AC outlets.
8. Slide the cable cover into place on the back of the scanner then secure it
with the three M3 screws provided.
9. Connect AC power to the transformers. The outlets should be near the
equipment and easily accessible.
10. Configure the MS7220 for the appropriate interface configuration settings.*
* The MS7220/host cable connection is interface dependent. Refer to the
installation steps provided for the type of interface required for your
application.
