S7FTXC-PCA (Style-7) Network Transceiver
The S7FTXC-PCA combines two FT-10 interface ports that allow the transceiver to meet Style-7 wiring requirements.
The two ports on the S7FTXC-PCA, when used with true style-7 wiring requirements, create a point-to-point type
network segment allowing up to 8,000 feet between nodes that use the S7FTXC-PCA. The separate FT ports allow
two twisted pair connections so that a cabling fault on one segment will not affect the other.
The S7FTXC-PCA has four diagnostic LEDs that are visible when the board is installed onto a NION.
• Packet - Blinks when a packet is received or transmitted.
• Status - Blinks steadily when no network traffic is present and blinks rapidly when processing.
• P1 ERR and P2 ERR - These LEDs (P1 for Port1, P2 for Port 2) denote error conditions when they blink.
NOTE: The S7FTXC temporarily stops processing when an error occurs. This suppresses noise propagation throughout the network
For more information about Style-7 network configuration refer to the Local Area Server manual 51544.
NOTE: When using the S7FTXC with a NION-232B, relay 2 on the NION-232B (LED D13) will activate
when a wire fault is detected by the S7FTXC. When used with a Simplex 4010 NION LED D2 will light.
