Determining the NII Value from a Terminal

An important part of configuring the IN-tact1101 is determining any NII codes in use. The NII code is used to route transactions from the terminal to the correct host processor. In the IN-tact1101, this configuration is done on the IN-tactSetup > Application Setup > Host Port Settings screen.

In some cases, all terminals may route to a single processor. In other cases (like this example), multiple processors may be used. Knowing the correct NII codes to use becomes even more critical in these cases. For customers who do not use NII routing, this procedure can be ignored.

By defining and enabling multiple host processors, the end-user terminals send POS transactions to the destination specified in the NII portion of the TPDU sent from the terminal per each transaction. The use of the NII value allows those terminals initialized with the same NII to be matched for transmission of all traffic to the associated primary IP address. Other entries on the screen define the IP address or URL used for routing, whether or not an SSL configuration is needed (encryption and authentication are required to be performed by the IN-tactdevice), and whether the connection is established on a permanent or on-demand basis.

The NII value can be extracted from the terminal by doing a hex dump. The hex dump can be forwarded to the ISO or support center that is configuring the IN-tact1101.
