1. Connecting the cash register system to the VMS system
To connect a cash register system to the VMS system, you normally need a crossed RS-232
interface cable (null modem cable). However, with some manufacturers, instead of a null
modem cable you need a 1:1 interface cable (RS-232 extension). For more information, see
the installation instructions for your cash register system.
When using an interface cable, make sure it is not more than 15 m long.
For longer distances, use an interface converter (RS-232

RS-485 or USB

RS-485).
The following illustrations show the various connection options:
