This section explains how to connect INPAS terminals to KkmServer, using the INPAS Q25 as an example. It covers connection methods via DualConnector, USB to COM (SmartSale mode), and Ethernet SmartSale (recommended).

Connection via DualConnector using the INPAS Q25 terminal as an example.

  1. Download links:
    DualConnector v1.2
    ".NET Framework 4.0" and higher
    Java 7, 8, 11 (Only for DualConnector v2)
  2. After installing the required .NET Framework and Java libraries (optional), proceed with the DualConnector installation. It is important to select the correct version. The version for the provided terminal can be confirmed with your bank (v1 and v2).
  3. After installing and connecting the terminal to your computer, configure the DC service by selecting the connection port and speed. The DC service may require a USB driver. This driver can be obtained from the bank that provided the terminal or selected from the INPAS download library. (Figure 1)
