Summary of Computer Operations

Summary of Computer Operations

Computer operations allow the instrument to be configured and controlled from a personal computer (PC), including data exchanges with the instrument memory card. The computer interface is via an RS-232 link between the instrument RS-232 port and a PC serial COM port. The PC gives operation and configuration commands to the instrument, and the instrument returns status signals (alarms, for example) and scan measurement data. PC operations can be in real time with a dedicated RS-232 connection, or the instrument can be connected to a PC for configuration and then removed for distant operations. Memory Card features are described in Chapter 3, Memory Card Operations.

PC applications software Hydra Series II Starter Package (Starter) and Hydra Series II Logger Package (Logger) (optional) operate the RS-232 computer interface. The software packages are described in separate technical manuals; however, each accomplishes the following:

Starter (supplied)

Starter is a menu-driven software package used to transfer

 

configuration data from and to the instrument, log measurement data

 

collected by the instrument, and manage the acquired data.

Logger (optional)

Hydra Series II Logger is an optional full featured Windows based

configuration

and data logging package. It can communicate with two Hydras at

 

once and can also utilize telephone modems for remote

 

applications. A brochure with complete details is available.

Custom software can be developed by the user in GWBASIC, Quick BASIC (QBASIC), or Quick C using the computer interface command set, which is described in this chapter.

The RS-232 computer interface between a instrument and a PC is discussed in the following paragraphs in this sequence:

∙Connecting the Instrument to a PC

∙Configuring the Instrument for Computer Operations

∙Configuring the PC for Computer Operations

∙Testing the Instrument/PC RS-232 Interface

∙Computer Interface Commands and Operation

Connecting the Instrument to a PC

The two most common configurations for connecting the instrument to a PC are shown in Figure 4-1. The instrument RS-232 port (DB-9 connector) is cabled to a PC serial COM port that uses either a DB-9 connector or DB-25 connector. The connecting cable can be fabricated (see Appendix D) or ordered from Fluke as an option (see Chapter 1).
