 RS-232 extensions

If the RS-232 interface is used, the distance between POS-terminals and the POS-server may be longer than the maximum cable length. The following RS-232 extenders can be used in this case:

  1. RS-232 repeaters;
  2. RS-232 to RS-422/485 converters;
  3. RS-232 to Ethernet converters.

Note.

 If the RS-232 to Ethernet converter is used, the POS-terminals should be connected to the POS-server via LAN.

 Devices installed on the POS-server

The number of POS-terminals to be connected to POS-server COM-ports may exceed the number of available COM-ports. The following communication devices can be installed on the POS-server in this case:

  1. multiport RS-232/422/485 serial cards;
  2. multiport converters from RS-232/422/485 to USB (Serial-USB);
  3. multiport converters from RS-232/422/485 to Ethernet (Serial-Ethernet).

Note.

The communication device selection depends on the type of connection between POS-terminals and the POS-server.
