'Motionnet
®
' interface
Use a dedicated cable or LAN cable (category 5 or higher) as the communication cable for "Motionnet
®
".
"Motionnet
®
" wiring uses a line transceiver (RS-485) and a pulse transformer (about 1000 µH).
Attach a terminator only at the end of the transmission line.
The same effect can be obtained regardless of whether the terminator is installed before or after the pulse transformer.
The terminating resistor must be equal to the characteristic impedance of the communication cable.
SO, SI, and SOEH pins also have a 5 V tolerant function, allowing direct connection of TTL level 5 V line transceivers.

Single-step connection circuit
To connect one "G9006" to one "Line transceiver", connect as follows.
C a u t i o n
*1 The wiring from the transmission line to the line transceiver must be shortened linearly.
Long wiring can reduce communication performance.
