The GE Fanuc Genius bus communication protocol requires the use of terminator resistors, such as the GE Fanuc IC660BLM508 75-ohm bus terminator resistors, to reduce reflected wave signals. When the terminal resistance is not used with the protocol, there will be high-frequency noise in the network, resulting in transmission errors. The GE Fanuc IC660BLM508 75-ohm Bus terminal resistor is a 75-ohm terminal resistor shipped in a 4-resistor package, specifically designed to connect to the Genius bus network and reduce signal reflection in the network. The GE Fanuc IC660BLM508 75-ohm bus terminal resistor is a packaged electronic component made of carbon with 4 connection leads designed to connect to any end of the Genius bus network. The 75 ohm value of the resistance level matches the characteristic impedance rating of the Genius Bus protocol.
The connection leads of the GE Fanuc IC660BLM508 75 ohm bus terminal resistors are not marked, but are easily identified when the resistors' leads point to the right. There are four ports vertically arranged on the resistor, from top to bottom are SER 1, SER 2, SHD IN and SHD OUT ports. Because it is a packaged component, the GE Fanuc IC660BLM508 75 ohm bus terminating resistor requires no special maintenance or environmental protection measures other than the normal procedures used to protect and maintain the Genius I/O block to which it is connected. Care should be taken when handling GE Fanuc IC660BLM508 75 ohm bus terminal resistors, as ESD discharge may occur.
