２－２．Setting LAN communication
２－２－１．Preparation for setting
To control this one by LAN communication, it's need to some setting items by 10Base-T/100Base-T
communication cable. Setting protocol is telnet protocol by TCP/IP connection.
To connect network by this one, IP address, subnet mask, and Port number must be set to this unit.
Factory default is "IP address is 192.168.1.55", "sub net mask is 255.255.255.0" and"Port number is 7777 "When connecting PC directly, it's need to use cross cable. Otherwise using HUB module, it's no need
to use cross cable.
The way of connecting PC directly is as follows.
It's need to set IP address and subnet mask to your PC.
Set IP address to 192.168.1.10, and subnet mask to 255.255.255.0, for example.
about the way of setting address to your PC, see your PC manual.

In these setting items, only IP address must be set. Other items may be no change to set.
If you enter wrong number by mistake, you'd better to restore above data.
２－２－３．Turn back PC set data
If you change setting data of PC, turn back PC data to initial condition.
２－２－４．Connecting test
Let's try connecting test by optional Windows software such as "telnet".
Example test data is "telnet 192.168.1.55 7777" in MS-DOS prompt screen.
（IP address number must to be set number preliminary. ）When in telnet operation, send data "VER?" which are expected reply data.
If reply data is like ”1.00 05-07-07", then communication line is right.
"Telnet" function contains hardware and software function, when disconnect line, line must be cut off
by "telnet" software operation before hardware disconnection.

２－３．Setting USB communication
２－３－１．Preparations for setting
Driver software for USB (Universal Serial Bus) operation is downloaded from our web server.
By installing this software, connecting is done like a COM port connection.
Switch on a NCT08-01, connect USB cable, then there will be message box that shows "New hardware
device was found". According to PC directions, specify the folders of downloaded driver software.
When the driver software installs are done, open the "Control Panel" ( START → Control Panel),click the "System" icon. Then property display of system appears. Select the "Device Manager".
Confirm the USB Serial Port (Com*) number in the tree between Port display.
Select the USB Serial Port (Com*), click Advanced in Port Setting display. It's possible to change
COM Port number. Click the check box Disable PNP □ , it's possible to short operation time inconnecting USB cable again.
２－３－２．Connecting test
Launch RS-232C communication software such as hyper-terminal including PC.
Set COM port number which is known in previous item, it's need to check communication line is available
or not. In this case It's no need to set baud rate. Send the command data such as "VER?", then get
the reply "1.00 04-09-03", there is no problem for communication

12/28

２－４．Connect signal cables
２－４－１．Connect communication cables
Connect the communication cable to USB port or LAN port on rear panel.
There is no need to connect both side, but there will be no problem even if connect both side.
If connected both side, latest command will be valid to the unit.
２－４－２．Connect count signal
Connect count signal cable to CH0 to CH7 LEMO connector which are on front panel.
It' s possible to count maximum 8 channel signals.
Before connecting the cable it's need to set signal change switch (TTL side or NIM side), according
to input signal. (See fig.2-1)
２－４－３．Start signal (TTL positive logic)
TTL positive logic signal starts counting action.
The width of start signal pulse must be more than 100ns.
It's possible to check the count start status by LED lamp on front panel.
It counts from start signal "ON" to stop signal "ON".
When this signal is not useful, it's possible to start by software commands.
２－４－４．Stop signal (TTL positive logic)
TTL positive logic signal quits counting action.
The width of stop signal pulse must be more than 100ns.
It's possible to check the count stop status by LED lamp on front panel.
It counts from start signal "ON" to stop signal "ON".
When this signal is not useful, it's possible to quit counting by software commands.
２－４－５．Gate signal (TTL positive logic)
Gate signal is TTL positive logic signal.
When gate signal goes "L" counting action stopped during "L" period.
When gate signal goes "L" LED lamp is "OFF" during this period.
LED lamp goes "ON" during gate signal is "H" when counter starts.
When gate signal is no connection, gate signal is equal to logic "H".
While gate signal is "ON", the count data are stored in memory on synchronous gate
data acquisition mode. Data can be stored up to 10,000 memory address.
２－４－６．Monitor out signal (In counting, TTL positive logic)
Run signal goes "H" when counting action is valid. It means count start and "Gate signal" arein "H" logic, and LED goes "ON".
It's useful to use more than two counter units. Connecting this line to "Gate signal input" of anotherunit, another units go active counting action. Of course another units must be active in count mode
before Run signal go "H".

４－５－５．Amount of time for data downloading
NCT08-01B uses serial communication (38400BAUD) for LAN interface.
The data download speed via LAN is about 3,800 characters (3.8KB) per second.
Decimal data download may be slower because of converting hexadecimal value into decimal.
Hexadecimal data download can ignore that delay for convert.
The data download speed via USB is 3 - 5 times as fast as via LAN because of 8 bit parallel
communication for USB interface. For this reason, in the case of downloading so much count data,
you can download faster if you request hexadecimal data via USB, and ignore not using counter data.

5．Firmware update
For NCT08-01B it's possible to upgrade firmware via communication tools.
Here is an overview of operation.
It's possible to use USB and LAN communication.
You can download software for update and its user's manual from following URL.

http://www.tsuji-denshi.co.jp/download_file/lan_rs_file_send.EXE
http://www.tsuji-denshi.co.jp/manual_pdf/pm16c_04xd_vup_soft.pdf

software for updateuser's manualThis is an example to install software by free soft "Tera Term" using LAN.
① Fist download the version upgrade software by Internet then unzip the file.
② Run "Tera Term" software.
In case of LAN mode, select "TCP/IP" enter IP address and port NO. of NCT08-01.
In case of USB mode, select "SERIAL" and click PORT number (COMX) which is assigned to USB port.
Operate "SETUP" to "Terminal", set "New-line" is CR+LF with Receive and Transmit usage.
Put check mark into Local echo, then select "OK".
Try put into command "VER?", then if there is reply, connection will be no problem.
③ By "Tera Term", select "file" and then click "send file".
Opening "File Selection Window", specify the file name which is already installed procedure ①．
Then it begins the download.
④ it's possible to check download program file by PC.
When receiving data, the "COUNT" LED lamp of unit NCT08-01 turns on and off slowly.
⑤ After receiving data for about 20s, the "COUNT" LED lamp goes to fast on and off mode then ROM writing
session begins. After 5s, "COUNT" LED lamp turns off then this session will be done.
⑥ Stop "Tera Term" then cut off the line TCP/IP or USB, turn off power line of NCT08-01.
Turn on power of NCT08-01 again, the firmware version will be new.
Without turning off power line, it gets start by "RESET" command.
There are two pieces of flash ROM(FROM) loaded inside, new firmware is installed to one piece
which is not used at now. After finishing writing a session, new one (written just now) is activated.
So after this session, by power on mode and "RESET" command, new program will start.
It is possible to check the version of working FROM by the command "FROM?"
Reply data is like these,"FROM0", "FROM1".
It is possible to specify the version of working FROM by the command "FROM0" or "FROM1".
After specifying FROM version, turn on power action or "RESET" command will start again by specified
FROM version. It is useful to compare old and new firmware version.

25/28

If you miss the download work and program doesn't work, it's possible to recover initial version firmware
by the ROM print board inside.
This is the procedure of recover the program to initial state.
１．Cut off power line, open the left-side cover panel. Slide the dipswitch 2 "ON" side.
Dipswitch 1 keep "OFF" side.
２．Put on power line while shortening "GATE" input signal, "COUNT" LED turn on and off for about 15s.
After that "COUNT" LED turn off and session will be done.
３．Put off power line again, then slide the dipswitch 2 "OFF" side. Dipswitch 1 keep "OFF" side.
４．Put on power line again then program starts by initial version.
From now the latest file must be installed by procedure ① to ⑥．
6．Synchronous drive of multi units
It's possible to operate multi units synchronously.
Then NCT08-01 contains 8 CH counters, it's possible to count more than 9 channels at synchronous modeusing multi units.
Here are procedures of this usage.
Connect the RUN signal (TTL OUT) of first unit to the GATE signal (TTL IN) port of second unit.
It's the same way to the third unit.
Send "DSAS" command to latter unit. The latter units don't stop counting automatically.
Send "START" command to latter unit. The latter units start counting action.
Depend on your usage, put on "GATE" signal to first unit.
Depend on your usage, preset timer stop command to first unit. ("CLTM","ENTS","STPRdddd")
Depend on your usage, preset counter stop command to first unit. ("CLPC","ENCS","SCPRdddd")
Activate count mode of first unit by the command "START".
This procedure activate more than one unit at the same timing chart.
Similarly, if you use several NCT08-01B,you will acquire 8n channel data with gate signal data acquisition.
7．Regulations and guidelines
Regarding NCT08-01B when it receives data read command, it stops count and timer action for 120 ns.
This stopping period is essential to get latest data to latch 32 bits count data.
If you read out count data 20 times/sec, total stopping period of counter is 120ns×20 = 2.4μs/sec.
Even if you read one or all counter at once, all counter and timer stops simultaneously, andstopping period is always 120ns. Therefore, you may read data by minimum commands.
On timer stop mode or counter stop mode, there is no error measurement caused by counter stop on reading.
When in counting pulse during "GATE" signal which comes from outside, you'll notice that counting period
is shorter than read out period.
When in timer stop mode or counter stop mode, there is no dead time to read out count values.
(b) Notes when multiple counter units at simultaneous control(See ６．Synchronous operation by multi counter units.)
In case of using multiple counter units at simultaneous control, if you read count in progress data of each units,
only units which are read count data stop count operation in 120ns.
Therefore, note that it occurs some errors among count data of modules because of
condition of count pulse, timing of reading, and dispersion of times of reading.
Example: Case of reading 20 times a second to one module onlyThis module have 120ns * 20 = 2.4μs delay in every seconds.
Count error occurs by 2.4μs/s(0.00024%)
