Sets the contrast of the display screen.
Determines the period of inactivity before the meter

is turned OFF. A timer is started when the meter is
turned ON and is reset each time a key is pressed.
When the timer reaches the value set in this
parameter, the power is automatically turned OFF.
(NOTE: Setting this parameter to 0 disables the
Auto Off timer. When running from line power, the
meter does not automatically shut off.)

Displays current life of the battery.
At 10%, a warning screen will appear.

Sets volume for the audio beep.
Determines the number of samples that are

averaged in the digital filter. The software has a
Digital Filter that averages the readings to produce
a stable display.
(NOTE: Increasing this setting will cause a more
stable display. However, it will also cause a slower
response to small changes. The best setting is the
smallest number that provides a stable display.)

ZEROING PRESSURE SCALES

– When there are no pressure inputs connected to the

unit, the display should read “0.” It may be necessary to zero the pressure scales to

remove any errors due to ambient conditions. This is done by depressing the

key until the zeroing instructions are displayed, then depressing

simultaneously to begin the process. The “ZEROING…” message will flash while the scale

is being zeroed. When the zeroing instructions are displayed again, the process is

complete.

NOTE: Each sensor needs to be zeroed separately.

11

LOW BATTERY

– When the battery life reaches 10 percent, the LOW BATTERY message

box will be displayed.

Typical display with
“Low Battery” message
box.

NOTE: The unit is shipped with a red plug in the Power Input that prevents it from turning

on and using up the battery during transport. This plug must be removed before use.

LINE POWER – A 2.1 mm jack is provided for the optional 9 VDC power supply

(BC20 - 21100, BC20 - 21101) that may be used for continuous run applications. It

bypasses the internal battery when plugged in.

12

KEYS

Six tactile-touch keys are provided for system operation:

– This key turns the unit off and on. The unit will return to the main screen that

was active when it was turned off.

– In the DISPLAY MODE, these keys toggle the display through the

available main screens.

In the SELECT MODE, if a parameter has been highlighted, these keys will scroll through

the available settings.

– On any screen, there are a number of parameters that may be selected and

changed. This key sequences the cursor (Highlight) through those parameters.

– This key is used to Hold (freeze) and Reset (unfreeze) any of the input displays.

Depressing this key will hold the currently displayed Pressure or Temperature reading until

reset. Each input can be held independently.

When active, the word “HOLD” is in the display. Depressing this key on a screen that is

held will reset that input and remove the word “HOLD” from the display.

NOTE: In the composite screen, the hold feature requires that the specific input be

selected using before is used.

13

– This key toggles the unit into and out of the Setup Mode. Depressing this key

will enter the Setup screen where the configuration can be viewed and adjusted.

Depressing the key again will exit the Setup Mode and return to the previously viewed main

screen. This will also save any changes to the internal EEPROM memory so they will be

retained even with the power turned off or battery removed.

ANALOG OUTPUT

scaled to match the 0 to Full pressure range of the selected sensor(s). The scaling voltage

can be selected from 1.0 to 4.0 VDC in 0.1V increments.

The source for the analog output is selectable in the Setup Mode. The DC Output

parameter can be selected to track Pressure 1 (Pres1), Pressure 2 (Pres2) or

Temperature (Temp).

The frequency response of the DC Output is limited to less than 100 Hz sine wave.

– The unit may be ordered with an analog output. This output is

COMMUNICATIONS

Since the meter does not handle a great deal of data, the link has been optimized to allow
the user, through very simple instructions, to control and interrogate the meter. The
following section describes the JPC Protocol used by the meter.

The JPC Protocol consists of 6 basic commands:

R - READ
W - WRITE
U - UPLOAD
Q - QUICKSEND
V - VERSION
X - CANCEL

The data format is standard ASCII and all data are BCD values.

The following is a breakdown of each of the commands and the way they are accessed.
The meter will echo all characters that are typed to it. When used with a terminal, this will
provide the appropriate display. When used with a computer system, this will provide direct
feedback of the fact that unit has accepted the data.

All commands are completed with a carriage return from the computer. All commands will
be acknowledged by a carriage return, line feed ($0D,$0A). If a command is not valid, the
meter will respond with “??”. All commands are not case sensitive.

16

READ/WRITE COMMANDS

The READ command is utilized to read from the meter any of the gathered data. The
command is entered as a letter followed by 2 numbers, followed by a carriage return:

R(Location)(Return)

The 'R' indicates to the meter that the command is to be a READ command.

The Location contains two digits that indicate the data location that is to be read.

The carriage return indicates that the command is to be activated.

The WRITE command allows the user to update the system settings. The write command
is entered as a letter followed by 7 numbers, followed by a carriage return.

W(Location)(Data) (Return)

The 'W' indicates to the meter that the command is to be a WRITE command.

The Location contains two digits that indicate the data location that is to be read.

The Data contains five digits that indicate the data that is to be written at the desired
Location.

The carriage return indicates that the command is to be activated.

Note 1 – The units for the pressure data are determined by the setting in Location 6 and 12.
This may be set via the Write command or manually using the Range Key. See
Description Page for Ranges.

Note 2 – The units for the temperature data are determined by the setting in Location 18.
This may be set via the Write command or manually using the Range Key. See Description
Page for Ranges.

Note 3 – Writing to Min/Max will reset them to the current value. Any data up to 5 digits will
trigger the reset. This is the same function as selecting the Min/Max item in the display and
pressing the key.

19

The following is an example of how the Read/Write commands are used. For display
purposes, the symbol <cR> will be used to identify a carriage return ($0D), and the symbol
<LF> will be used to identify a line feed ($0A).

UPLOAD COMMAND

The Upload command allows the user to read all of the selected device data from locations
1 through 16 with a single command. The data will be transmitted as a single block with
each location separated by a carriage return, line feed ($0D,$0A).

The following is the format for this command:

U (Return)

See the table in the Read Command section for details on the data structure.

QUICKSEND COMMAND

Quicksend is a feature that allows the user to receive an automatic update of all of the
meter data without any user interaction. When the Quicksend feature is turned ON, the
meter will automatically send all of the device data every half second. The Quicksend
feature is toggled ON and OFF with the Quicksend command.

The following is the format for the 'Q' command:

Q (RETURN)

See the table in the Read Command section for details on the data structure.

21

VERSION COMMAND

The Version command allows the user to read the Software Version that the unit is running.

To read the Version, the following syntax is used:

V (RETURN)

CANCEL COMMAND

The CANCEL command is simply a way to re-establish proper control, should an error
occur or an incorrect command be transmitted. For the most part, an incorrect command
will simply be ignored and the meter will prepare for an additional command. However, a
command may be cancelled midstream by transmitting an 'X' (ASCII). This command does
not require a carriage return, nor will it acknowledge with a carriage return. However, it will
echo an 'X' to indicate that the CANCEL command has been received.

The command may also be utilized as a clear and/or acknowledgement of the meter being
on line.
