220.21 DATA EQUIPMENT INTERFACING

The DTA-E Unit is provided with an RS-232C for

interfacing with Data Terminal Equipment (DTE). Prior to configuring a system with data capability, you

should complete the Job Specification (ND-20234) sheets provided with the CPU.

An understanding of system programming is required to complete the Job Specification sheets (See Chapter

3, Programming).

This section contains specifications for the DTA-E Unit and precautions that must be followed when installing the DTA-E Unit.

1.Interface

The DTA-E Unit is equipped with a female RS-232C

connector to support the RS-232C interface. For

internal data communication, speeds of up to 9.6 kbps can be accommodated by the RS-232C interface. For connection of an interface unit; a 25 pin RS-232C connector (refer to Figure 200-5 for Straight Cable Pin connections) is provided with the configuration shown in Table 200-15.

2.Grounding Requirements

Proper grounding is required to protect the DTA-E Unit and the data terminal equipment connected to the DTA-E Unit. Usually, data terminal equipment with an RS232C interface has its frame connected to earth ground. Ensure that data terminals connected to the DTA-E Units are properly connected to earth ground

via circuit ground of the AC power cord used in the data terminals.
