**Note: 1.** As shown above, there is no need to upgrade to CX-Programmer version as long as the functions added for unit versions are not used. **2.** CX-Programmer version 7.0 or higher is required to use the functional improvements made for unit version 4.0 of the CS/CJ-series CPU Units. With CX-Programmer version 7.2 or higher, you can use even more expanded functionality. 

## **Device Type Setting** 

The unit version does not affect the setting made for the device type on the CX-Programmer. Select the device type as shown in the following table regardless of the unit version of the CPU Unit.

## **External Interface** 

A CJ1-series CPU Unit provides two communications ports for external interfaces: a peripheral port and an RS-232C port.

## **Peripheral port** 

The peripheral port is used to connect a Programming Device (including a Programming Console) or a host computer. It can also be used as an RS-232C port by connecting a suitable cable, such as the CS1W-CN118 or CS1W-CN @ 26. The connector pin arrangement when using a connecting cable for an RS-232C port is shown below.

## **RS-232C Port** 

|**Item**|**Specification**|
|---|---|
|**Communications method**|Half duplex|
|**Synchronization**|Start-stop|
|**Baud rate**|0.3/0.6/1.2/2.4/4.8/9.6/19.2/38.4/57.6/115.2 kbps<br>(See note.)|
|**Transmission distance**|15 m max.|
|**Interface**|EIA RS-232C|
|**Protocol**|Host Link, NT Link, 1:N, No-protocol, or Peripheral Bus|



**Note:** Baud rates for the RS-232C are specified only up to 19.2 kbps. The CJ Series supports serial communications from 38.4 kbps to 115.2 kbps, but some computers cannot support these speeds. Lower the baud rate if necessary.
