RS232
The following steps describe how to properly install the cables for an RS232 MS2420 application. The scanner/Diva scale
must then be configured to match the host's RS232 parameters. Cable installation alone does not guarantee that the
MS2420 will communicate properly with the host system.
Configuration bar codes are located in the MetroSelect Configuration Guide (
MS2x20 Stratos Series Scanner/Diva Scale Configuration Addendum (
1.
Turn off the host system.
2.
Plug the 10-pin RJ45 end of the RS232 interface cable (
into the 10-pin socket labeled Scanner Host RS232, on the bottom of the MS2420. Refer to the figure on page 17.
3.
Connect the other end of the RS232 cable to the proper communication port on the host device.
Before continuing, verify that the RS232 interface cable is connected to the appropriate interface socket on the
scanner. An incorrect cable connection can cause communication problems or potential damage to the scanner
and/or terminal.
Steps 4 and 5 are for dual cable interfaces where the scale and the scanner connect to the host with their own separate
communication cables. Skip to step 6 for a single cable interface where the scale and scanner connect to the host with a
single cable.
4.
Plug the dual interface cable (
of the MS2420.
5.
Connect the other end of the dual interface cable (
host's scale device.
6.
Plug the optional remote scale display cable (
Scale to Display, on the bottom of the MS2420.
7.
Plug the external power supply (
MS2420.
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.
Metrologic recommends using a switched AC outlet. The switch should be located on the operator's side of the
checkout counter in close proximity to the MS2420 to facilitate calibration and service of the unit.
8.
Connect AC power to the transformer. If the AC outlet is equipped with an on/off switch, turn the power on.
