Customer is requested to prepare a communication cable fit for the control unit to be
connected by the host computer. Connection cable W-BF-02 * and W-BF-28 * (RKC
product) can use to connect host computer. If noise is a factor, customer should use a twisted
pair cable (not included) or something to that effect.
* Shields of the cable are connected to SG (No. 6 pin) of the H-PCP-J connector.
The 6-pin type modular connector should be used for the connection to the H-PCP-J module.
Recommended model: TM4P-66P (Manufactured by HIROSE ELECTRIC CO., LTD.)
