Cable Installation (Interface Specific)
RS232
The following steps describe how to properly install the cables for an RS232 scanner application. The scanner/Avery scale must then be configured to match the host’s RS232 parameters. Cable installation alone does not guarantee that the scanner will communicate properly with the host system.
Note: Configuration bar codes are located in the MetroSelect Configuration Guide (PN
1.Turn off the host system.
2.Plug the
3.Connect the other end of the RS232 cable to the proper communication port on the host device.
Stop: 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 (PN
5.Connect the other end of the dual interface cable (PN
6.Plug the optional remote display cable (PN
7.Plug the external power supply (PN
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.
Using a switched AC outlet is recommended. The switch should be located on the operator’s side of the checkout counter in close proximity to the MS2420 scanner 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.
9.Turn on the host system.
10.Scan the Recall Defaults bar code.
