Abstract
A terminator for a transceiver device for transmitting data signals to and receiving data signals from a second transceiver device over a transmission line therebetween. The terminator has a transmitter connected to the transmission line for transmitting data signals to the second transceiver device, a receiver connected to the transmission line for receiving data signals from the second transceiver device, a termination resistor connected to the transmission line for improving the transmission characteristics of the transmission line, and a switch device between the termination resistor and the transmission line. The switch device is closed for a portion of the time when the receiver is receiving data signals from the second transceiver device such that when it is closed the termination resistor is connected to the transmission line, and is open for the remainder to the time such that when it is open the termination resistor is not connected to the transmission line.
