Cable Installation (Secondary Honeywell Scanner)
The following steps describe how to properly install the cables between a secondary Honeywell scanner
and the MS2421/MS2422/MS2431 scanner. The MS2421/MS2422/MS2431 and the secondary scanner
must then be configured to communicate properly. Cable installation alone does not guarantee that the
MS2421/MS2422/MS2431 scanner will communicate properly with the host system and secondary
scanner.
Note: Contact a customer service representative before connecting another manufacturer’s scanner to the
MS2421/MS2422 as a secondary scanner.
Configuration bar codes are located in the MS2xxx Stratos Series Configuration Addendum
(PN 00-02034x) under Scanner Configuration Bar Codes: Auxiliary Port, Quick Start for a
Secondary Honeywell Scanner.
1. Refer to pages 22 - 26 for the type of interface (RS232, RS485, 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 (PN 57-57099x-3 or PN 57-57099x-3-12)
into the RS232 socket of the secondary scanner (see the figure on page 29).
3. Connect the angled end of the RS232 AUX cable (PN 57-57099x-3 or PN 57-57099x-3-12) into the 10-
pin socket labeled
‘Aux RS232 In’, on the bottom of the MS2421/MS2422/MS2431 scanner.
Note: The MS2421/MS2422/MS2431 series’ aux port requires the signals; transmit, receive, RTS
& CTS from the secondary scanner.
For Rev G Units or later: The MS2420/MS2430’s auxiliary port will support 5VDC devices with a
700mA maximum current.
For Rev F units or earlier: The MS2420/MS2430’s 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 Honeywell scanners can receive power
from MS2420/MS2430: the MS9520, MS9540, and the MS5145.
4. This step is required for secondary devices that require >5VDC and/or 700mA current to
operate. Skip to step 5 if the secondary device requires ≤ 5VDC.
Plug the power supply into the secondary scanner’s PowerLink cable (PN 57-57099x-3 or
PN 57-57099x-3-12)) and connect AC power to the secondary scanner.
Note: 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/MS2431 scanner and the secondary scanner. The auxiliary input
port’s data format must match the main output format of the secondary scanner.
Note: Refer to the MS2xxx Stratos Series Configuration Addendum (PN 00-02034x) under
