5.1 Operating modes
The operating modes are described below.
On reaching a preset value, the counter continues to count to the
next preset value. Preset values are always processed in the
sequence: preset value 1, preset value 2. Any values can be chosen.
External or manual resetting can be carried out at any time.
Preset value P1 serves as a preliminary signal and functions as a
self-adjusting preset. The preliminary signal always switches to the
input value before the final signals is given. Any second preset value
can be chosen.

The internal phase discriminator performs the necessary evaluation.
5.3 Output responses (Output Modes)
Signal output response is determined by the following:
– Programming of the preset value, output time, output logic and
output function;
– external resetting;
– external counting direction control.

NE215Open interface description
7Open interface description
7.1 General information
The open interface is of the RS485 type. It is possible to send the
commands documented in the „Description of the Open Interface“
for remote control to the counter. The interface allows to call up data
and to change the programming of parameters not relevant for the
values to be calibrated.
In general, the counter is operated via the serial interface on a
personal computer – that is why the external device will be called PC
for short in the following. However, it is also possible to use another
device with similar features.
7.2 Transmission protocol
Transmission is effected character by character in ASCII code. Each
character consists of 8 bits. The 8th bit is the parity bit; in case of „no
parity“, the 8th bit will always be transmitted as a zero. The counter
responds to every request of the PC via the serial interface – if data
have been transmitted correctly.
The transmission of characters is introduced by the start-of-text character
<STX> and closed by the end-of-text character <ETX>. In addition, the
tachometer also sends a <CR> (carriage return) after the character
<ETX>. This allows the input (in high-level languages such as BASIC) of a
complete record of data with only one command. The character <STX> is
followed by an address allotted to the counter. This allows a target
approach of the counter in a serial network. The address is followed by
the indication of the line (position) that is to be read out or programmed.
In case of a programming instruction, the line indication is followed by a
„P“ (program) and the data (parameters).
24
The protocol is split into three groups, as described in the following:
a) Reading of storage locations (READ instruction):
<STX> Address Line <ETX> [<CR>]
b) Programming of storage locations (WRITE instruction):
<STX> Address Line P [VZ] Data <ETX> [<CR>]
c) Special commands:
<STX>Address Parameter <ETX> [<CR>]
<STX>Start of Text (02Hex)
Address00..99 (device address)
Line01..XX (please refer to operating plan)
PProgramming command
DPrint command
VZPlus/Minus sign, only indicated if value
is negativ
DataProgramming data
Parameter Special commands
<ETX>End of Text (03Hex)
<CR>0DHex (Control character „carriage return“).
„CR“ needs not be indicated (optional),
will however, always be returned by
counter.
NE215Open interface description
Important
The blanks between the particular characters of the commands
only serve the purpose of better legibility. The input at the PC must
be effected without blanks. Control characters (less than 20Hex) are
set in „pointed“ brackets. If a false protocol has been sent by the
PC, the counter will return an error message. Please read the
paragraph regarding error messages on page 29 under 7.7.
7.3 Reading of storage location
All storage locations that are indexed with a line number in the
programming scheme (except the separating lines that are indexed
dashes) can be read out. The protocol: <STX> Address line <ETX>
[<CR>] can be used for each line. The return answer of the counter
may vary in the protocol length from one line to the other. This
depends on the data length of the individual storage locations.
The counter can also be read out if operated in the RUN mode as
well as in the PGM mode. The only difference is that the return
answer of the counter will contain an „R“ or a „P“ in the mode
parameter, as described in the following.
Answer to a Read instruction (general):
<STX> Address Line Mode VZ Data <ETX> <CR>
Mode P = Counter is in Programming mode
R = Counter is in RUN mode
VZ Plus/Minus sign, only indicated if value is negative
Data Max. number of digits, with leading zeros w/o
decimal point.

7.4 Programming of storage locations
All storage locations that are indexed with a line number according
to the programming plan, except for the separating lines (that are
indexed by dashes) and the lines 1, 5, 6 and 8, may be programmed.
25
The protocol: <STX> Address line P [VZ] data <ETX> [<CR>]
can be used for each line. The answer of the counter that is returned
after every programming step is the same as for the readout of the
line.
All storage locations may, principally, be programmed during the
RUN mode in the programming mode.
Please refer to page 27 (under 7.5.2) to find out how to switch to the
PGM mode.

7.5 Special commands
In the case of special commands, we are talking about instructions
that do not refer to any line number, with the exception of the
commands „Clear count“ and „Output to printer“.
NE215Open interface description
26
7.5.1 Clear counts
The counts XP (line 1), totalizer (line 5), batch counter (line 6), and
operating time meter (line 8) can be cleared via this special
command. It concerns all lines that cannot be programmed. All other
lines, such as preselections, are cleared by programming the value
ZERO (as described under item 4).
The instruction to clear corresponds to a reset via the C key and/or to
an external reset if a reset input is available.
The response (answer) of the counter when clearing is the same as
when reading the corresponding line.
General: <STX> Address Line <DEL> <ETX>
Example: Clearing of preselection counter XP

7.5.2 Switch counter to PGM mode or RUN mode
This command allows you to switch the counter upon every call
between the PGM mode and the RUN mode.
The current line, as with the reading command on this line, will be
returned as an answer.
General: <STX> Address <DC1> <ETX>
Example: Address=35, Status=RUN mode, Current line = 1, Count=0.15
Command: <STX>35<DC1><ETX> <DC1> = 11Hex
Answer: <STX>3501P00000015<ETX><CR>
If the instruction is repeated, the program switches back to the RUN
mode.

7.5.5 Clearing the error message
This command allows to clear error messages appearing on the
counter display. It is only possible to clear the error message that
can be cleared via the C key on the device itself (e.g.: not Error 1 or
2). The contents of the current line will be returned as an answer.
<Data>: Up to 11 data at choice may additionally be sent to the counter,
Example: Data_Time=29.08.94 10:32:20

7.6 Output to the printer
The command parameter „D“ allows the initiation of the output of
the lines 01, 02, 03 and 05 to the printer.
7.6.1 Appearance of the printout
The printout comprises
- date and time that need to be sent along by the PC upon a print
command
- optionally further data, which the PC may send along
- the length measurement needing to be calibrated, indexed by the
sign * .
LENGTH*000123.45m
7.6.2 Printout of the XP values
The protocol addressed to the counter is as follows:
Counter address=35, Line=01, Count XP=000223.68
PC Command: <STX>3501D<Date_Time> <Data><ETX>
<Date_Time> must be given in the following format:
<TT.MM.JJ hh:mm:ss>
TT: TagMM: MonatJJ: Jahr
hh: Stunden mm: Minutenss: Sekunden
TT:DayMM: MonthJJ: Year
hh: Hourmm: Minutesss: Seconds
All values must be 2-digit values and the punctuation must be
observed. (The characters < bzw. > / < and/or > only serve the
purpose of indexing and should not be transmitted.)
which will then also be printed. The sign * should not occur,
otherwise it will be ignored by the counter, i.e. it will not be sent to
the printer.
Date and time serve the purpose of clearly allocating the printed
length measurement to the data of the PC. After printing, the
counter will automatically trigger a carriage return so that the length
indication will always stand on a separate line.
PC Command: <STX>3501D29.08.94 10:32:20<ETX>
LENGTH*000223.68m
The counter will only respond to the PC when all characters have
been sent to the printer. The protocol then returned will contain the
value emitted to the printer:

7.6.3 Error message
If the PC does not send the date and the time as described above,
i.e. date/time are not complete or the punctuation is wrong, there
will be no printout and the counter sends an error message to the
PC.

7.6.4 Printout of the lines 02, 03: preselections P1 and P2
As these are not length measurements that need to be calibrated,
the value of the preselections P1 and P2 is not printed with the sign
*, and it is also not necessary that the PC sends Date/Time along.

7.6.5 Printout of Line 05: totalizer Σ
The value of the totalizer is printed with the sign *. Similarly Date/
Time will have to be sent along as with the XP value, otherwise the
same error message will be returned.
Totalizer count Σ=001223.68,
Data_Time=29.08.94 10:34:52
PC Command: <STX>3505D29.08.94 10:34:52<ETX>
SUM *001223.68m
7.6.6 Printing via key [Print] / [Druck]
If you press the key [Druck] during operation and if the value of the
preselection counter XP, the preselection P1, the preselection P2 or
the totalizer Σ are displayed, then the value will be indexed with the
sign * as with the PC command for the counter XP (line 01) and for
the totalizer (line 05). There is no printout of any additional data.
7.7 Error messages during data transfer
If the PC sends a wrong data protocol to the counter (e.g.: line that
does not exist or letter instead of digit), then the counter will return a
corresponding error message to the counter. In order to still receive
an error message after an error, the control character <STX> and the
address must at least be correct. If this is not the case, the data
block received by the counter will not be considered, and the
counter will not respond to the PC. If the PC does not receive a
response after a request has been sent, i.e. not even an error
message, then a fatal error has occurred. This may be the case if the
control character <STX> or the address are missing and if the
interface parameter of PC and counter are not congruent. Should
these be correct, however, then it can only be a matter of a failure of
the hardware or of the data line.

9. Supplement to the scaling factor manual
(May 1999)
This supplementary manual is describing the modification of the
counter’s operation manual regarding application of the scaling factor
and the alibi printer SP 298 of the company Star. It is according to the
third addendum of licence No. 1.62-3251.11 file number 5.23-99037480
dated 24.06.1999.
Address for printer: DATAMEGA Mikrodatentechnik GmbH

Tel.: 089/56017-300
9.1 Modifications in Chapter 2: „Get to know the counter“
The counter consist of
- preset counter with 2 presets (PTB-approved) and scaling factor
- batch counter with preset and multiplier
- totalizer, (PTB-approved) with scaling factor
- hour counter
The device is approved by the German Physical-Technical Authorities
(PTB) for calibration. The PTB-approved register system provides a
printer model Star SP298 with serial interface RS232.

Supplement to the operation manual with scaling factor
9.2 Modifications in Chapter 3: „Counter connection“
New pin assignment for pin 15: scaling on.
9.2.1Modifications in Chapter 3.3: „Assignment of signal inputs“
Pin 15 is for activating the setting of the scaling factor (line 22
programming level). Prior to sealing the pins the setting of the
scaling factor is activated by the signal trigger “scaling on” (pin 15).
Activation is realized by connecting pins 15 and 20, by a bridge from
18 to 19 or by 15 to 19, if 18 has to be connected to 20 (refer also to
page 8 “programming of input logic” in the operation manual).
After having set the scaling factor, the connection to pin 15 has to be
removed. Once being sealed, this pin is no longer accessible and the
scaling factor is indicated in the programming level without allowing
any alteration.
9.3 Modifications in Chapter 5: „programming the counter“
The scaling factor of the main counter is shown in programming line
22. Any modification is only possible if pin 15 is being activated (see
above).
Programming line 22:
Line 22 Scaling factor main counter
1.0000 Default
0.0001 Scaling range 0,0001
99.9999 up to 99,9999
