232 MONITOR PLUS

Overview of the 232 Monitor Plus

Figure 1 on page 3 shows the many

ways you can use the 232 Monitor

Plus.

1Troubleshoot printers to

eliminate handshaking

problems.

2Determine transmission

quality of a leased line.

3Remotely operate the 232

Monitor Plus from any ANSI-

standard CRT terminal.

4Flag cables with broken wires

5Troubleshoot terminals.

6Monitor data transmission.

NOTE: Both connectors on the right side are

connected on all pins. So you may elect

to only attach one side via a “Y” cable to

avoid disrupting circuits.

Using This Manual

This Installation and Operation

Manual provides detailed

information about the commands

and submenus available in the View

Mode, and describes the values

allowed in the Configure Menu.

The 232 Monitor Plus Keyboard

Each key of the 232 Monitor Plus

can serve three distinct functions.

Thus, there are three ink colors on

most of the key labels:

• RED= Main text (keys that

appear on a standard keyboard)

• GREEN=Subtext

• WHITE=Upper text

(commands)

Brackets [ ] on the Screen

To conserve screen space, the 232

Monitor Plus references command

keys (the white “upper” text on a key)

by the letter of the alphabet that

resides on the same key (the key’s

red letter). The alphabet letter is

placed in brackets [ ] to indicate it

is a reference to the command that

shares the key with the alphabet

letter.

For example, the command

PULSE CAPTURE

would appear on screen as the letter

Uenclosed in brackets, as shown

below:

Quick Reference/Quick Setup

Before You Start,

Read Me First!

Make the best use of your time and this

device: read the rest of this Installation

and Operation Manual. This Quick

Reference section is intended to accom-

pany you in the field. It is not meant as a

substitute for the rest of the information

in the manual. Also, please read the

following information about the unit’s

battery and the power switch.

Alkaline battery and the power switch

When storing the 232 Monitor Plus for more than

several days, turn the main power switch to the OFF

position (slide to the right). This eliminates all

current consumption from the battery. A fully

charged battery will last for about three (3) months

if the main power switch is left in the on position.

Memory is preserved for one (1) full year (even

when the main power switch is in the off position).

How to start the 232 Monitor Plus

Make sure that the main power switch is in the ON

position (slide to the left). Push the POWER ON

key (lower right of the keyboard).

Proper shutdown

1. Push the [RESET/SHUTDOWN] key.

2. Press the [START/STOP] key.

3. The computer shuts down: it turns off

and preserves memory and option settings.

Setting automatic shutdown to save battery life

The 232 Monitor Plus can shut itself off

automatically after a user specified number of

minutes without activity. To enable this option:

1. Push the [MENU] key.

2. Push and hold the [PAGE DOWN] key until

the auto off option appears.

3. Push the ↓ key until the auto off option

flashes.

4. Enter the number of minutes to delay

before shutdown. For example, enter the

number 10 to force the unit to shutdown

after 10 minutes without data entry or

keyboard activity.

5. If you make a mistake, push the ← key to

delete erroneous input.

6. Push [MENU] to exit the menu.

The unit will now shutdown after the set number of

minutes pass without data or keyboard activity.

How to transmit and capture data

1. Push the [OUTPUT SERIAL] key.

2. Push the [START/STOP] key to start

output.

The 232 Monitor Plus will begin to transmit data and

capture the transmitted data. Any returned data on

the RD line will be placed in the RD buffer.

3. Push the [START/STOP] key to end this

process.

For more information, see Chapter 1, View Mode.

Quick Reference

Quick Reference/Quick Setup

Production capture of data

1. Use the 3-connector ribbon cable.

2. Attach the single-male connector on this

cable to the female connector on the upper-

right-side of the unit.

It’s not necessary to run data through the unit. both

right-side connectors work for monitoring.

3. Attach the other end of this cable to a

working circuit.

4. If the baud rate, word size, and parity of the

data stream match the current settings, the

232 Monitor Plus will start capturing and

viewing data.

5. If you get framing errors, push [A] to

autoconfigure TD on the 232 Monitor Plus.

Peruse captured data

1. Push the [PAGE UP] key anytime during

the data capture process. The scrolling

action stops and cursor movement will

freeze.

The cursor may now be manipulated with the four

arrow keys ( ↑ ↓ ← → ), and the HOME, END,

PAGE UP, and PAGE DOWN keys. You may also

press the period ( . ) key to execute a GOTO

command; this will allow you to go to a specific

buffer location.

2. When the default menu option enabling

status is set, the value of the data directly

under the cursor position is shown in

binary, decimal, and hexadecimal radices.

3. Press [RETURN] to resume full speed

scrolling or press [END] two times to get to

the end of the buffer.

4. When scrolling, push [←] to slow the

scrolling rate and [→] to speed the

scrolling rate. The variations in scrolling do

no affect the data capture process.

5. To go to the beginning of the capture

buffer, press [HOME] two times.

Advanced features: STATUS key

The status display is normally enabled.

1. Push the status key to show the cursor

location and character values.

2. Push the [STATUS] key a second time to

show the current state of the modem

interface leads.

3. Push [STATUS] a third time and the state

of each signal (when selected character was

received) is shown.

For more information about status screens, see

Chapter 1, View Mode, p.18.

How to exercise a parallel printer

1. Attach the 25-pin ribbon cable to the left-

side connector.

2. Attach the other end of the cable to a

parallel printer.

3. Push [P] for print parallel.

4. Push [START/STOP] to begin printing.

5. Push [START/STOP] to stop printing.

Examining captured data in HEX

With data in the buffer, press [H] and the entire

screen will change to HEX representation. Return

to Text display by pushing [H] again.

Create or edit a string

1. Push [E] for edit.

2. To create string1, type the string of

character. Use the cursor key to edit your

string.

3. Push [START/STOP] to exit the editor.

Strings are used:

• to start and stop triggers

• as custom output strings

• as timer triggers

• as buffer search patterns.

For more information about editing strings, see

Chapter 1, View Mode, pp. 8–9.

Quick Reference/Quick Setup

When in View Mode, you can:

• Wait for transmitted data to appear.

• Turn off the unit (SHUTDOWN then STOP).

• Press HELP to get more information.

• Execute any commands (e.g. Autoconfigure

TD, Status).

• Switch to the Configure Menu mode to set

communications parameters.

There are 35 command keys set in white text. Push

HELP in View Mode to see the command keys listed.

For more information, see pp.6–18

Setting Options & Values

Several command keys open sub-menus; each

submenu offers options followed by values. Setting

the values and scrolling through options is done

primarily by using the arrow keys, and the PAGE UP,

PAGE DOWN, HOME, END and RETURN keys.

(see the illustration below). When in an options

menu a selected option value is depicted in reverse

video. To increment the value, press RETURN or

→. To highlight a different value, use the keys as

shown in the illustration below.

Quick Setup

Before You Start,

*NOTE: Synchronous data only.

Stop Bits 1, 1.5, 2

The number of stop bits set to read in async mode.

Data Bits 8, 7, 6, 5

The number of data bits set to read.

Parity Odd, Even, None

The parity set to read. Choosing Odd or Even

assumes an extra bit at the end of the data bit.

Mode Async, Monosync, BSC (bisync),

SDLC, Isochronous

• Async is for asynchronous transmissions.

• Monosync and BSC are byte-oriented sync

protocols. Monosynchronous uses an 8-bit sync

character; BSC uses two 8-bit sync characters.

• SDLC is a bit-oriented sync protocol that uses an

8-bit flag (hexadecimal 7E) to mark the

beginning and end of message envelopes.

• Isochronous is a clocked async mode that allows

asynchronous data to be sent over synchronous

circuits.

Code ASCII, EBCDIC, IPARS, BAUDOT

The way you would like to view your data.

Sync Char 1 (hex value)

In monosync mode this byte is used as a pad

character on all transmission—output, loop, and

answerback options. To learn how to enter hex

values, see 1.3, Entering Integers and Hex Values.

Sync Char 2 (hex value)

Refers to the second synchronous characters in BSC

mode or the receive synchronous character in

Monosync mode. To learn how to enter hex values,

see 1.3, Entering Integers and Hex Values.

NOTE: Sync character one and two are loaded

automatically in SDLC mode.

Data encoding NRZ, NRZI, FM0, FM1

These are the four data encoding methods.

• NRZ is used in sync and async applications.

• NRZI, FM0 (biphase space) and FM1 (biphase

mark) are all used in various sync applications.

Ig Mul Syn Char Yes, No

(Ignore multiple synchronous characters)

If you select “Yes”, this tells the unit not to capture

synchronous characters. If you select “No”, this tells

the unit to capture all synchronous characters.

Drop Sync RTS/CD Yes, No

Select “Yes” to drop synchronization when the

Monitor detects Ready To Send or Carrier Detect.

Resync Char None, (hex value)

Selecting “None” has no effect on synchronization.

Setting a (hex value) means synchronization is

dropped when this character is received.

Resync On Char On, Off

Selecting “On” drops synchronization when it

detects Ready To Send or Carrier Detect.

Log Events No, 1Fill, Cont.

Used to keep a log of certain events. See Time Events

(p. 19, Chapter One) on how to view the log.

• “No” means you do not want to keep a log.

• “1Fill” means to fill the log buffer once (when

log buffer is full, stop collecting logs).

• “Continuous” means you want to continue

capturing logs, and when the buffer is full, to

clear logs to make room for newer logs.

Quick Reference/Quick Setup

Exclude Off, Control Data, Text Data

Off—has no effect on capture.

Control Data—the control data will be excluded

from the capture (in other words, only the data

between the start text character (STX) and the end

text character (ETX) will be captured.)

Text Data—text data will be excluded from the

capture; in other words, the data between the start

text character (STX) and the end text character

(ETX) will not be captured.

Start Txt Char (value)

See “Exclude” above. Specify the STX character.

End Txt Char (value)

See “Exclude” above. Specify the ETX character.

Remote Off, On

Insert this unit into an RS-232 circuit, then turn on

remote with this menu function to take remote

control of this unit. Useful for loopback tests when

you don’t have an assistant in the remote location.

Remote Baud 57600, 19200, 9600, 4800, 2400,

1200

Communication rate with the remote Monitor Plus.

Invert Rec. Bits Yes, No

Yes—inverts the sense of all incoming bits.

SDLC Status Yes, No

Yes—displays status of SDLC.

CRC Preset Zeros, Ones

Presets the value of CRCs to “ones” and “Zeros”.

SDLC Search Node Search Node All, Node number

(hex value)

Choosing “All” (0) captures all nodes. Setting a

specific Node number allows you to specify one

SDLC node in a loop or polled circuit.

SDLC Search Disable, Enable

Choose enable to go ahead and search for the node

specified above in SDLC Search Node.

Status Messages Normal, Long, None, Short

Notifies you of events when “Normal” is selected;

e.g., END OF BUFFER. Turn them off (None), view

briefly (Short), or linger on the screen (Long).

Idle Display On, Off

“On” displays “Waiting for data” on power up.

Error Messages Fatal, Warn, None

NOTE: When the 232 Monitor Plus is turned on, it

will always pass data through itself, even if

it cannot recognize speed or other

configuration parameters.

Fatal— the Monitor stops receiving at certain

hardware errors (a change in line speed, etc.); press

any key to begin receiving again. You can enter

Configure Menu and change a parameter.

Warn—a message will appear at certain hardware

errors, but receiving will continue.

None—suppresses error messages.

Suppress Capture Off, RD, TD, Both

Choose whether you want data captured as follows:

Off Capture data from both lines

RD Don’t capture RD data.

TD Don’t capture TD data.

Both Disables capture on both lines. Useful

when collecting modem control trans-

itions and hardware handshake changes.

Auto Off (min) (value)

Setting a value means the unit will turn itself off after

it has been idle for (value) number of minutes.

Display Mode Compressed, Expanded

Compressed—data line characters displayed

sequentially to conserve display space.

Expanded— data line characters followed by a blank

to facilitate reading at high speeds.

Buffer One fill, Continuous

One Fill—stop collecting data when buffer is full.

Continuous—continue to fill the buffer and discard

the oldest data on a first-in/first-out basis.
