The following steps describe how to properly install the cables between a secondary Metrologic scanner and the
MS2421/MS2422 scanner. The MS2421/MS2422 and the secondary scanner must then be configured to communicate
properly. Cable installation alone does not guarantee that the MS2421/MS2422 scanner will communicate properly with the
host system and secondary scanner.
Contact a Metrologic customer service representative before connecting another manufacturer’s scanner to the
MS2421/MS2422 as a secondary scanner.

1. Refer to pages 16 - 20 for the type of interface (RS232, IBM 46xx, etc.) required for your application. Follow the cable
installation steps under the appropriate interface before continuing. Once the communication and power cables have
been installed follow step 2 below for the secondary scanner installation.
2. Connect the straight end of the RS232 PowerLink AUX cable ( MLPN 57-57099 x-3) into the RS232 socket of the secondary
scanner (see figure on page 23).
3. Connect the angled end of the RS232 AUX cable ( MLPN 57-57099 x-3) into the 10-pin socket labeled Aux RS232 In, on
the bottom of the MS2421/MS2422 scanner.
Important: The MS2421/MS2422 series’ aux port requires the signals; transmit, receive, RTS & CTS from the secondary
scanner.
MS2421/MS2422 scanner auxiliary port will support 5VDC devices with a 150mA maximum current. If the auxiliary
device exceeds this specification an external power supply will be required to power the auxiliary device.
The following Metrologic scanners can receive power from the MS2421/MS2422 scanner: the MS9520, MS9540,
and the MS5145.
4. This step is required for secondary devices that require >5VDC and/or 150mA current to operate. Skip to step 5 if
the secondary device requires ≤ 5VDC.
Plug the power supply into the secondary scanner’s PowerLink cable ( MLPN 57-57099 x-3) and connect AC power to the
secondary scanner.
Check the AC input requirements of the power supply to make sure the voltage matches the AC outlet. The outlet
should be located near the equipment and be easily accessible.
5. Configure the MS2421/MS2422 scanner and the secondary scanner. The auxiliary input port’s data format must match
the main output format of the secondary scanner.
