Connection Configuration

The connection configuration for using the E5jK Digital Controller Read Protocol is shown below.

RS-232C Connection

CQM1H

E5jK

 

Serial Commu- nications Board RS-232C port

Serial Communications Board

RS-232C: D-sub 9 pin female

Signal name

Pin No.

E5jK

RS-232C: Terminal block

Terminal No. Signal name

Shielded cable

Note 1. The communications configuration is a one-to-one configuration and the maximum cable length is 15 m. 2. Use a shielded twisted-pair cable (AWG28i or greater) for the cable.

RS-485 Connection

CQM1H

E5jK

Serial Communica-

tions Board RS-485 port

E5jK

Up to 31 Units can be connected.

E5jK

Note 1. The communications configuration is a one-to-one configuration or a one-to-N configuration. In the one- to-N configuration, up to 32 units including the Serial Communications Board can be connected.

2.The maximum cable length is 500 m. Use a shielded twisted-pair cable for the cable (AWG28i or great- er).

3.Connect a terminator only at both ends of the transmission path. For instance, in the example shown below, connect a terminator to the Serial Communications Board and Unit No.30 and do not connect any
