If communication errors occur frequently due to the operation environment or the
communication distance, connect termination resistors to the host computer side.
Up to 16 SRZ units can be connected to a host computer communication port.
The 6-pin type modular connector
should be used for the connection
to the COM-ML.
Recommended model: TM4P-66P
