2. INTRODUCTION, CUSTOM ASCII SERIAL PROTOCOL
This manual applies to our programmable digital panel meters, counters and timers with Series 2
firmware. Before applying this manual to your device, verify that the label states “Series 2.”
The Custom ASCII Protocol is a simple serial communications protocol which is optimized for use
with Series 2 programmable digital panel meters, counters and timers. It is compatible with
RS232 and RS485 signals. It supports point-to-point and multipoint (or multidrop) communications, with addressing of up to 31 devices on the same RS485 serial data line.
Digital panel meters, counters and timers require a plug-in option board for serial communications. This can be an RS232 board, RS485 board, or RS485 Modbus board. The RS485 and
RS485 Modbus boards are electrically equivalent, but the RS485 board uses RJ11 connectors,
while the RS485 Modbus board uses RJ45 connectors. All of the serial board support the Modbus
protocol. The two RJ11 or RJ45 connectors are wired in parallel to allow daisy chaining with no
need for a hub. One of the jacks is equipped with two indicator LEDs.
The Modbus Protocol is a software-selectable alternative to the Custom ASCII Protocol and can be
used with RS232 or RS485 signal levels. It is an industry standard which allows devices by
different manufacturers to be digitally addressed on the same RS485 serial data line. However, it
is substantially more complex than the Custom ASCII Protocol. For additional information, please
refer to the separate Modbus Protocol Communications Manual.

Alarm Status
No Overload
Overload
5.1 SERIAL COMMUNICATION FORMAT
The serial communication format for both RS232 and RS485 is the following:
Mode ................ Full Duplex (Separate transmit and receive lines) and Half Duplex (RS485 only)
Baud Rate ......... 300, 600, 1200, 2400, 4800, 9600, 19200 selectable by front panel Menu item
“Ser 1”, Sub-menu item “Digit 4” for DPM, "Digit 5" for counter.
Parity ................ None
Word length ...... 8 data bits
Stop bit ............ 1
5.2 MEASUREMENT DATA FORMAT
The basic measurement data format consists of 8 ASCII characters for the DPM, such as
+999.99<CR> and 9 characters for the counter, such as +9999.99<CR>, where <CR> is the
carriage return character. The first character is always a plus or minus sign. A decimal point is
always furnished, even when it follows the last digit.
Adding a Line Feed Character to the Basic Format
Printers and other devices that receive the measurement data may require a line feed character
<LF> following the <CR>. The line feed character <LF> may be selected in “Ser 2”.
Adding a Coded Data Character to the Basic Format
It is possible to add a coded character from A to H to the data string according to the following
table to indicate the alarm and overload status of the device. If used, this character precedes
the <CR>, so it is the last printable character in the string. With the optional <LF> and coded
character selected, the data string will consist of 10 characters for the DPM +999.99A
<CR><LF> and 11 characters for the counter +9999.99A<CR><LF>.
Neither Alarm set
Alarm 1 set only
Alarm 2 set only
Both Alarms set
A
B
C
D
E
F
G
H
For example, a coded character “G” indicates that Alarm 2 only is set, that the DPM is in the
overload condition, and that zero blanking has been selected. This information is useful when
data is supplied to a computer for listing and analysis, or when data is supplied to a Remote
Display in a Master-Slave configuration.
- 9 -
Page 10
The Counter and Scale Meter are capable of supplying more than 1 measurement value (or
“Item”) with each reading, as selected in “Ser 3”. In the counter, there can be up to 3 Items
plus a Peak value, depending on the selected Function. The scale meter can transmit Net, Gross
and Peak weight.
Values are transmitted in a continuous string with no space between them. If the 5th digit in
“Ser 3” is set to 1, the termination characters of <CR> and optional <LF> appear after each
value. If the 5th digit is et to 0, the termination characters appear only once at the end of the
string. In either case, if included, the coded character appears at the end of the last value only.
5.3 NETWORK CONFIGURATIONS
The instruments can operate in a point-to-point mode using RS-232 or RS-485, or in a multipoint mode using RS-485.
The point-to-point mode is a direct connection between a computer (or other digital device)
and the instrument.
The multi-point mode is a connection from a host computer to a multiplicity of instruments
bused together with their inputs and outputs connected in parallel. For long cable runs, the last
device should have a termination resistor installed. It is necessary to set up each device on the
bus with a different address from 1 to 31. To command a particular device, its address is used
in conjunction with the command, and only that device responds. The outputs of all of the
devices on the bus are set to a high impedance state, except the device being addressed. The
device addresses range from 1 to 31, with 0 being a special address to which a meter responds
only internally (e.g. Reset), but does not transmit any response on the output lines. All devices
may be commanded simultaneously with a 0 address, and there will not be any output
response contention. Addressing of meters can be set in “Ser 2”.
A device operating in a point-to-point mode must also be addressed. Although any address will
suffice, it is suggested address = 1 be selected as a standard for the point-to-point mode.
5.4 OPERATING MODES
The instruments can operate in a Continuous Mode or Command Mode.
In the Continuous Mode, measurements are continuously transmitted by the meter in a
standard data format. Please see the next manual section.
In the Command Mode, the meter does not send any data automatically, but responds to commands received from a host computer. Please see the manual section following the Continuous
Mode.

6.1 OVERVIEW
In the Continuous Operating Mode, measurements are continuously transmitted by the instrument in a standard data format using printable ASCII characters at a user-selectable rate
ranging from 50 or 60 Hz line frequency down to one measurement every 72 seconds. This
data may be received by a remote display at a distant location, by a printer for data logging
purposes, or by a host computer for data analysis or system control.
Both hardware (RTS) and software (XON/XOFF) handshaking are available for RS232, but
neither is available for RS485.
6.2 INSTRUMENTS WITH DPM OR SCALE METER MAIN BOARD
The transmission rate of the measurement data can be selected in “Ser 1”. The meter
conversion rate equals the AC power frequency (50 or 60 Hz). Any baud rate may be used, but
if less than the minimum baud rate in the table, the transmission rate will decrease accordingly.

6.3 INSTRUMENTS WITH COUNTER / TIMER MAIN BOARD
The transmission rate of the measurement data can be selected in “Ser 1". Data transmission is
initiated at the end of the calculation time following the gate time. Data is completely transmitted for one measurement before the calculation of the next measurement is started.
Therefore, the reading rate is influenced by the baud rate, the number of items transmitted, and
gate time. If the selected gate time is less than that shown in the table below, it is not the
determining factor of the reading rate. If it is greater, then it is the determining factor. Time
intervals (reciprocal of rate) between transmissions at the reading rate are:

The data transmission rate may be reduced by sending data every other reading, every fourth
reading, or less. This selection is made in “Ser 1”. A computer, if busy with other tasks, may be
unable to keep up with the faster data rates of the meter, so a handshake function is available
that provides the computer with control over the meters’ data transmissions.
6.4 RTS CONTROL
RTS control does not apply to RS485. DPMs and counter / timers have two RS232 RTS modes:
unlatched and latched.
In the unlatched mode, the measurement transmission is enabled by a high RTS level and is
disabled by a low RTS level. When disabled, any character being sent is completed. When
enabled, any characters remaining in the data format are transmitted before the next measurement transmission. The computer, when its receive buffer is nearly full, takes the RTS line
low to halt data transmission. When its receive buffer has emptied, it takes the RTS line high to
enable more data transmissions. Some measurements could be missed in the process. The
latched and unlatched modes are selected in "config" "digit 2" in the DPM and by “Ser 3” in the
Counter and Scale Meter.
.65s
.31s
.14s
.06s
.01s
.01s
In the latched mode, the RTS input is polled every 3.3 ms. When a high level is detected, RTS
is latched true, even though the RTS line goes low immediately. At the end of each calculation,
the latched RTS value is checked. If it is true, a complete measurement transmission (from 1 to
4 values) is made without interruption, regardless of the state of the RTS line during that time.
At the end of the complete transmission, the latched RTS value is reset false, even though the
RTS line may be high at that instant. The RTS latch does not go true again until the RTS line is
first returned to a low level after the completion of the transmission and then is taken high
again. Latched control provides “print command” operation by sending a transmission for each
RTS pulse. If a second pulse occurs during the transmission, it is not recognized.
6.5 XON / XOFF CONTROL
Applicable to RS232, not RS485. A measurement transmission is enabled by the receipt of an
ASCII XON character. It is disabled by the receipt of an ASCII XOFF character.

7. COMMAND MODE
Char #
Character
Description
7.1 OVERVIEW
In the Command Mode, the device does not send any data automatically, but responds to commands received from a host computer. These commands can be:
• To transmit the latest or peak measurement
• To reset the meter completely or just the peak value and/or latched alarms
• To display a value sent from the computer
• To transmit present setup parameters
• To receive new setup parameters,
• To monitor or alter data in selected memory locations of the meter.
The selection of either the Continuous mode or the Command Mode can be made from the
front panel Menu selection “Ser 2”. The meter will not respond to a command in the Continuous Mode, except the command “A1”, which puts the meter into the Command Mode.
7.2 COMMAND MODE FORMAT
The minimum format is 4 characters. Example: *5A1
After any command that causes a Meter Reset, such as C0, F, W, X, the Counter sends an “R”
character after the Reset is complete and the Counter is ready to accept a new command.
CHAR 1 - COMMAND IDENTIFIER
All commands begin with “*” followed by the meter address, then a command letter followed
by a sub-command number or letter. Additional characters may be appended. All commands
terminate with <CR> (<LF> ignored). The counter may be assigned a different recognition
character via the RS232 / 485 serial port, but will still recognize the “*”.

7.4 COMMAND MODE FOR REMOTE DISPLAY OPERATION OF DPM
OVERVIEW
A DPM can serve as a remote display that responds to values sent via serial communications
by a PC or by another DPM in a Master-Slave configuration. In one application, the DPM sends
readings to a PC, which then processes the readings and transmits values back to the DPM for
display. There are 3 modes in which the DPM may act as a remote display:
MODE 1: DPM with Signal Conditioner Card and not in Remote Display Mode
SETUP (left digit) = 0 4-1/2 digit DPM
= 2 4-1/2 digit DPM with Count by 10
= 3 3-1/2 digit DPM
The baud rate must be set the same as the source. The PC Controller uses the H command to
cause the display to halt it’s normal readings and display the value sent by Serial Communications instead. The DPM must be in the Command mode to receive the data. The data format
sent via Serial Communications is:
*#HSDDDDD.A <CR> where the decimal point is in front, behind (as shown), or
between the D’s (digits).
A total of 11 characters plus a CR must be included and sent as ASCII characters. Those in
quotes below are included as shown. The other symbols represent a range of characters except
for CR which is the ASCII character “0D”.
* = Command identifier
- 17 -
Page 18
# = Device address from 1 to 9, A to V, or 0 for common address
ALARM CONDITION
NO OVERLOAD
OVERLOAD
H = Command letter
S = Sign of value, space (or +) for positive, - for negative value
D = Digit from 0 to 9
* = Decimal point placement and must always be included
A = Alarm and overload character code, A to H
<CR> = Carriage return character
The following table lists the Alarm and Overload characters.
Neither Alarm on
Alarm 1 only on
Alarm 2 only on
Alarms 1 & 2 on
A
B
C
D
E
F
G
H
If the DPM is in the Continuous mode, it must be put into the Command mode by sending
*#A1 prior to sending the remote display value.
The Remote Display value remains on the display until one of the following occurrences:
a. The command *#C4 is sent removing the Remote Display value and returning to the
normal readings without resetting the DPM.
b. The command *#C0 is sent causing a Cold Reset of the DPM.
c. The command *#C1 is sent causing a Warm Reset of the DPM.
d. Front panel pushbuttons RESET and MENU are simultaneously pushed to cause a Cold
Reset of the DPM.
Notes: After the Remote Display value is entered, the DPM can be put back in the Continuous
mode with the command *#A0 without disturbing the display’s value. DPM must be in the
Command mode for a., b., or c. above. It may be put into the Command mode while displaying
a remote display value with the *1A1 command without affecting the display.
If PEAK (manual or external) or ALARM VIEW (manual) is activated while the remote value is
being displayed, the peak or alarm value is displayed and cannot be removed except by Remote
Display Reset (a., b., or c. above in Command mode) or by manual RESET. If a Remote Display
value is sent while in PEAK or ALARM VIEW, it is ignored, but when PEAK or ALARM VIEW is
turned off, the Remote Display value comes on.
MODE 2: DPM with Signal Conditioner Card and in Remote Display Mode
SETUP (left digit) = 1 Remote Display mode
The baud rate must be set the same as the source which may be a PC Controller or another
DPM. The format is the Slave Format. This is the same as MODE 1 above but without the

that data is transmitted from a DPM in the Continuous mode. The string of characters must be
exactly 8 characters plus the CR in length.
SDDDDD.A <CR>
No commands can be received in this mode but the front panel MENU can be accessed. Any
transmissions received other than properly formatted data will result in a meaningless display.
Alarm setpoints, Peak readings and external control functions are disabled while the Remote
Display value is being displayed. When the DPM is Reset, it displays RESET continuously until
data is received.
DATA FORMAT
*1HSDDDDD.A
S = Sign, either blank (for +) or D = Digit from 0 to 9, five digits total. Always include a decimal point even at the end.
A = Alarm character as defined in 8.4, Mode 1
7.5 COMMAND MODE FOR REMOTE DISPLAY OPERATION OF COUNTER / TIMER
The Counter has 13 Display Modes (0-12). Modes 0-5 are normal measurement modes. Modes
6-12 are dedicated to Remote Display without making any normal readings. In any of the 13
modes, remote display data may be received via RS-232 or RS-485 and be displayed. The
remote data requirements and the Remote Display capabilities vary for the different display
modes and selected Input Functions. The mode is selected by Menu item “ConFiG” “Digit 3”
from the following list:
0 Normal display, Exponent Overflow
1 Normal display, 999999 Overflow
2 1 right-hand dummy zero
3 2 right-hand dummy zeros

The addressable commands of Modes 0-6 can display remote data on one or more Counters
having the command address in a multi-point configuration or a single Counter having the
command address in a Point-to-point configuration. Modes 7 - 11 (B) do not use addressable
commands, but values only. They are primarily designed for Host Counter or Scale meter to
Slave Counter or remote display applications but may be used also in Host Computer to
Remote Display Counter configurations. Since the Host Counter may be selected to transmit up
to four sequential measurement values, Item 1, Item 2, Item 3 and Peak, (Scale meter transmits
up to 3 values) each measurement cycle, Modes 8-11 provide the ability of the Remote Display
to extract one of four sequential values and display it.
Modes 0-5 are normal counter modes that may be commanded as follows:
1. H Command.
2. K Command.
H Command. Overrides the normal display reading only.
H Command. H Command.
K Command. The value is not displayed, but is stored as Item 3 if Item 3 is not being

used. It may then become the source, if selected, for the Alarm comparison and the
Analog Output. Item 3 is normally only used for the Batch and Arithmetic functions.
3. L Command.
L Command. Both 1 and 2.
L Command.L Command.
In addition, the H, K, L commands may or may not include a coded Alarm character. If
included, this character always overrides the internal Alarm comparisons and determines the
alarm indicators, the relay operation and the alarm character sent with the serial communications. Readings continue to be made internally during Remote Display operation and may be
received by a Host Computer, manipulated, and returned as remote data. When reset by a *1C4
Command, the display returns to its internal readings, the Alarms to its internal comparisons,
the Analog Output to zero and the Item 3 value to zero. A signal conditioner board must be
present in these modes to return to normal readings. If no signal conditioner board is present,
any Mode setting from 0-5 automatically changes to Mode 6.
Modes 6-11 are used for remote display operation only. No normal readings are made. A signal
conditioner board is optional, and if present, is ignored. When reset, the display shows “rESEt”
until the first remote display data is received.
Mode 6 is an addressable remote display mode that uses the H, K, L commands.
Mode 7 is not addressable, and data representing a value to be displayed is received in a point-
to-point connection. In addition to being displayed, that value is put into Item 3, where it may
be selected for Alarm comparisons and/or for Analog Output. If a Coded Alarm character is
included, it overrides the internal alarm comparisons.
Modes 8-11 are able to extract one value of data from a sequence of values, and display that
particular value only. Using this mode, multiple slave counters connected to a Host Counter
- 20 -
Page 21
could each be displaying a different Item value. Also, the extracted value is put into Item 3
where it may be selected for Alarm comparisons and/or Analog Output. If a Coded Alarm
character is included at the end of the sequence, it is ignored. The remote display reading can
only be changed by Meter Reset, a *1C4 Remote display reset command, or another remote
display H or L command.
Mode 12 - Remote display "C" allows extraction of data from an ASCII string that contains
multiple data values or non-numeric characters. It can accommodate selected Start and Stop
characters. Any number of characters between the Start character and the data can be masked
OFF. Up to 8 display characters (including sign and DP) can be masked ON. Any number of
characters between the last displayed character and the Stop character can be masked OFF.
When CONFIG, CXXX is set, the meter is a Masked Remote Display, and the following parameters determine its operation. These must be set while the meter is set to something other
than CONFIG, CXXX, because that is the one setting for which there is no serial communication
with the meter. It is suggested to use CONFIG, 6XXX to set the following parameters, and then
to use CONFIG, CXXX for operation.
1. START character (set to 00 if none desired).
2. STOP character (set to 00 if none desired).
Note: Only one of the above can be set to 00.
3. Number of characters following the START character to be ignored.
4. Number of characters following the ignored characters to be displayed.
DATA FORMATS
The basic two Command formats of the data sent via Serial Communications are:
*#CSDDDDDD.A<CR><LF> where the decimal point is to the right of any one of the D’s (digits).
*#CSD.DDDEPA<CR><LF> This is the exponential format. The decimal point is fixed.
Alarm comparison and Analog Output are not valid in this format.
* = Recognition character
# = Device address from 1-9, A to V, or 0 for common address.
C = Command letter H, K, L.
S = Sign of value, space (or +) for positive, - for negative value. Sign is optional in
display modes 0-7, required in 8-11.
D = Digit from 0 to 9. Number of digits may be 1-6 in display modes 0-7, but must
be 6 in 8-11.
P = Power of 10. 0-9, A-F where A-F represents 10-15
A = Optional Alarm Character as defined in section 2.1
<CR> = Carriage return character
<LF> = Optional line feed character (ignored)

These basic Command formats are used when the Remote Display Counter is in display modes
Continuous Readings
Start Character
Stop Character
0 - 6. The basic Data formats are the same except *#C is omitted. The basic Data formats are
used in display mode 7.
Single or multiple (2-4) Data formats are used in display modes 8-11. Example:
SDDDDDD.SDDDDDD.SDDDDDD.SDDDDDD.A<CR><LF>
<LF> optional, “Ser 3” “Digit 5” = 0, termination characters only at end of data string or
SDDDDDD.<CR><LF>SDDDDDD.<CR><LF>SDDDDDD.<CR><LF>SDDDDDD.A<CR><LF>
“Ser 3” “Digit 5” = 1, termination characters at end of each data item.
7.6 RECOGNITION CHARACTER, AND START AND STOP CHARACTERS
The meter recognizes an asterisk ( * ) as the command recognition character. In the counter,
another command recognition character may be chosen to make the meter compatible with an
existing system. The meter will still respond to an asterisk. For all meters, in continuous mode,
a device ,such as a printer, may require a start and stop bit to recognize the data string being
sent. Normally there is no start bit and the stop bit is a carriage return <CR>. When the Counter
is in a normal operating mode (not Remote Display), SER 3, XDXXX can be set for the following
combinations:
D Command Recognition Character
