*1: Only half-duplex communication is supported when communication of NFLR121 is done through a two-wiring system.
*2: For connection terminals and cables, refer to “Field Connection Specifications” (GS 34P02Q30-01E).
*3: Connectors are fastened using metric screw threads (M2.6).
RS-232C interface uses CD line (for input signal monitor) and CS line (for transmission of flow controls). Wiring of these signal lines is necessary.
