Turn on terminator switch

Connect terminator resistor at a indicator where is longest distance from the host computer.

Settings of Parameters

Refer to 10.4. Parameter list of the function list.

Timing Chart

Keep delay time above 0.5 ms between last response and next command. Set response time (tr). [03 f- 9] < tr < [03 f- 9] + 50 ms

Make long delay time, when there is noise.

Make 4 ms or more from output finish to receiveing next command Hi-Z: Hi impedance
