CS1D-BC042D Omron, CS1D-BC042D Datasheet - Page 612

• Manufacturer Part Number: CS1D-BC042D
• Description: CS1D Dual CPU Exp
• Manufacturer: Omron

Specifications of CS1D-BC042D

• Lead Free Status / Rohs Status: Lead free / RoHS Compliant

Connection Example to Programmable Terminal (PT)
Direct Connection from RS-232C to RS-232C
Duplex Connections to Standby and Active CPU Units for Continuous Communications when
Switching to Simplex Operation
Example for 4-wire Connections
Note 1. The 4-wire connection methods must be used to enable the Programming Console function of the PT.
Connecting to the RS-232C Port on the CPU Unit
2. The CJ1W-CIF11 does not provide isolation. The total length of the transmission path must therefore

NS-series PT
be 50 m or less. If the transmission distance is greater than 50 m, use the NT-AL001, which provides
isolation, and do not include the CJ1W-CIF11 in the transmission path. When only the NT-AL001 is
used, the total length of the transmission path can be a maximum of 500 m. Also, connect the shield
to ground at one end of each cable.
