## Connection Configuration

IMPORTANT:

- When using more than one driver with one Display (except SP-5B10), there are the following limitations as listed below.

- The DH-485 driver of Rockwell Automation, Inc. cannot be used simultaneously.

- The Uni-Telway driver of Schneider Electric SA cannot be used simultaneously.

- The SIMATIC S7 MPI Direct driver of Siemens AG cannot be used simultaneously.

- This driver (communication speed: 38400 or more) cannot be used with both COM1 and COM2.

- 1:1 connection

- n:1 connection

NOTE

- The number of Displays (Slaves) you can connect depends on the External Device. Check the specifications of the External Device.

## Communication Settings

Examples of communication settings of the Display and the External Device, recommended by Pro-face, are shown.

WARNING

UNINTENDED EQUIPMENT OPERATION

Read and understand the instructions in this section to ensure data is properly transferred.

## Cable Diagram

The following cable diagrams may be different from cable diagrams recommended by External Device Manufacturer.

Please be assured there is no operational problem in applying the cable diagram shown in this manual.

- The FG pin of the External Device body must be grounded according to your country's applicable standard. Refer to your External Device manual for details.

- SG and FG are connected inside the Display. When connecting the External Device to SG, design your system to avoid short-circuit loops.

- Connect an isolation unit if the communication is not stable due to noise or other factors.

## Supported Devices

Range of supported device address is shown in the table below. Please note that the actually supported range of the devices varies depending on the External Device to be used. Please check the actual range in the manual of your External Device.
