RF-Link Technology RFL NCM manual Typical network example with all nodes having an NCM module

14.Set DIP switches SW6-7 and SW6-8 to set the word length (number of bits per character) in accordance with Table 1. If the system application mode is NMS, the word length must be set to the same word length as the local common module. Otherwise, any word length can be used.

NOTE

In any Application Mode, the Baud Rate, Parity and Word Length settings of the NCM must match at all nodes in the network. Additionally, In the NMS application mode, the Baud Rate, Parity and Word Length settings of the NCM and CM must match at all nodes in the network.

15.Switches SW7-1 and SW7-2 are only used when the NCM module is in the NMS application mode. In all other application modes these switch settings are ignored. Use DIP switches SW7- 1 and SW7-2 to set the CM address Pass Setting in accordance with Table 1. Typically, if all the nodes in a T1/E1 network have an NCM as shown in Figure 6, the address Pass Setting will be set to only pass messages with addresses equal to the local CM address of the NCM. This feature prevents the local node from responding to queries sent to remote nodes.

Place SW7-1 in the DOWN position Place SW7-2 in the UP position

In this example, all inter-node communication is done via the NCM path and FDL (Facility Data Link) is not used.
