Description - Operating Controls (cont.)

Figure 2.4

(Rear Panel)

Serial/Parallel Switch (Ref. A)

When this switch is set to SERIAL, new soft-

ware programs can be downloaded from a

personal computer (PC) to the TM-300 Con-

troller. For reliable operation, this switch

should be set to PARALLEL when operating in

normal RUN or STEP/JOG mode. When

downloading software, this switch must be set

to the SERIAL position.

Reset (Ref. B)

Pressing this button will stop current program

execution and reset the program line pointer

to the first line of the current program.

NOTE

The START button must be pressed to

restart program execution after Reset is acti-

vated.

RS-232 Conector (Ref. C)

This port allows communication between an

IBM compatible PC and the TM-300.

FSW (Ref. D)

This connector connects the footswitch to the

TM-300 controller.

Peripheral (Ref. E)

This connector provides connections from the

TM-300 Controller to motors on the machine.

Fuse (Ref. F)

The TM-300 uses a 1.5 Amp, 250 Volt, type

3AG fuse.

115VAC (AC Power Input) (Ref. G)

This is a 115VAC, 50-60 HZ input for AC

power.

Sealer (Ref. H)

Connects the heat seal assembly to the tem-

perature controllers.

I/O (Input/Output) (Ref. I)

This connector is reserved for future use. It

provides TWO logic level Inputs, one Motion

Busy Output, and a circuit Common, for future

hardware/software flexibility.

Air Regulator (Not Shown)

Connects the TM-300 to the air supply and

regulates the air pressure.

Counter Controls

Figure 2.6

Counter Module (Figure 2.5)

PST-Preset Select

This key can be used to select data to be dis-

played when the PGM input is active, although

for normal operation of the TM-300 this key is

not used.

Next Digit

This key selects one digit of data to be

changed. The first keypress will select the

left-most digit; additional presses will select

digits further to the right. The chosen digit will

flash twice per second. That digit may then be

changed with the + and - keys

+/- Increment/Decrement

The (+) key will change the selected (flashing)

digit of Preset or Program Data by adding 1 to

it. Rollover occurs from 9 back to 0. The (-)

key similarily subtracts 1, and will roll under

from 0 to 9. Holding either key down will

cause the digit to change repeatedly about

twice per second.

RST (Reset)

The counter is reset to 0 when this key is

pressed.

ENT (Enter)

This key transfers edited Preset or Program

Data to nonvolatile memory. The newly

selected value is not used until the ENTER

key is pressed. During normal operation a ten

second timer is in effect. If a Preset has been

changed but not entered, the Preset Data will

revert back to its old value after ten seconds of

inactivity.

Count Enable Switch (Figure 2.6)

The Count Enable Switch has two positions:

up and down.

In this position, the counter will be in its normal

operating mode. The count value will incre-

ment as the tape moves through the TM-300,

dependent on the setting of the Prescale value

(Pitch Setting).

Down

In this position, the counter will be disabled.

The TM-300 will function normally but the

count value will not increase.

Setting the Counter

Figure 2.7

Changing the End Count Value

The Preset Data value is the end count, or tar-

get value, for the current job. The machine

will cease operation when the counter module

reaches this value. To continue tape move-

ment, press the RESET button on the counter

module.

This diagram shows the sequence for entering

new values in the Preset Data. This proce-

dure can be done with the Count Enable

Switch in either the UP or Down position.

Use the NEXT DIGIT key to select one digit to

change. The selected digit begins to flash.

Change the selected digit with the + and -

keys.

When all of the digits have been correctly set,

press the ENTER key to store the new value

in memory.
