Mitsubishi Electronics T-60 Parallel I/O Made Simple

Load and convert SERIAL.BLD into a BASIC file (F8 function). Load it into

the T-60. Now, enter the terminal emulator (ALT-M then type T). Press the

RUN (F1) softkey on the T-60. You will be asked a question on your PC’s

screen. Answer it and press Enter. Watch what happens.

The ApplicationBuilder utilizes COM: PUT TEXT pseudocode to transmit

serial data. Actually, COM: PUT TEXT is converted into the PRINT #

BASIC statement to perform serial I/O. Data is gathered into a string

variable and output directly to the port in a single instruction. The COM:

INIT pseudocode generates a CONFIG # BASIC statement to initialize the

I/O. The complexities of the CONFIG statement are hidden from the

programmer with the simplicity of the pseudocode.

Parallel I/O Made Simple

If you thought Serial I/O was easy wait until you take a look at Parallel I/O.

The T-60 has 8 parallel I/O lines built into it. The ApplicationBuilder has a

host of I/O pseudocodes. To look at them, press F5 then press the I key. This

will display a list of available I/O pseudocodes.

An example program which sequences I/O bits one at a time is on your

ApplicationBuilder diskette: IO.BLD. Try loading it and running it. This

program uses on-screen messages to tell you about itself.

Please read the first part of

the DX.-COM.BLD program.

There are instructions on how

the DX Amplifier must be

setup to operate correctly.

This program (DX-COM.BLD) was written to demonstrate the capability of

the T-60 to control a EMERSON EMC DX Drive. The T-60 starts the

program at power on, and begins communicating with the DX Drive. It then

allows the user to make simple moves, download sequences, and scale units.

This program provides a good starting place for understanding how to

communicate with the EMERSON EMC DX Drives.

Connect the T-60 to the PC and to the DX Drive Amplifier as shown in Figure

17. T-60’s COM 2 port connects to the PC��s COM 1 or COM 2 port. This

connection must be made with a NULL MODEM cable. The T-60’s COM 1

port connects to the DX Drive Amplifier’s serial “B” port.

You will need a serial communications cable (Model number TIA-XXX), to

connect a DX Drive to the T-60. Such a cable can be obtained from

EMERSON EMC in three standard lengths:

Part Number Length

TIA-010 10 FT

TIA-025 25 FT

TIA-050 50 FT
