2.Connector pin assignment
10-2-2. Cable
The above diagram is for connecting a personal computer as a DTE (Data Terminal Equipment)
device. If it is a DCE (Data Circuit-terminating Equipment) device, connect pin to pin (DTR to
DTR, DSR to DSR etc.).
Cables should be prepared after checking connector type and pin assignments of the connected
device.
Adaptable connector : 9-pin D-SUB connector
(JAE DE-09SN, OMRON XM3D-0921 etc)
