１．Specifications
１-１．Abstract
This unit has fast eight channel 48 bit counters and a 40 bit timer.
It counts during timer set interval or until the limited set count value.
Setting interval for count is 1μs to 1,099,511.627775s. Setting limited count value is 1cts
to 281,474,976,710,655cts. *1)
This unit is assembled in a NIM 1 unit case. By connecting several units by RUN-GATE connection,
total count channels can be increased to 8×ｎ channels.
It's possible to control by LAN or USB communication.
The NCT08-02 is made as an upgrade model of NCT08-01. The commands are almost the same of the
NCT08-01.
*) The preset value is round down to multiple number of eight.

２．Before using
Input count signal level is fixed to fast NIM level for each channel.
Please confirm the signals are between the permitted level.(-12mA ～ -36mA: "1" -4mA ～ +20mA: "0")
The input impedance is 50Ω, so the voltage level will be -0.6V ～ -1.8V : "1" and > -0.2V : "0".
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 NO 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
NO is 7777 "

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 retore above data.
２－２－３．Turn back PC set data
If you change setting data of PC, turn back PC data to initial condition.
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.
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 NCT08-02, 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 in
connecting USB cable again.
Launch RS-232C communication software such as hyper-terminal included in your 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
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.

Connect count signal cable to CH0 to CH7 LEMO connector which are on front panel.
It' s possible to count maximum 8 channel signals.
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".
Without this signal you can alse start counting by software commands via LAN or USB.
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".
Without this signal you can alse stop counting by software commands via LAN or USB.
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".
Run signal goes "H" when counting action is valid. It means count start and "Gate signal" are
in "H" logic, and LED goes "ON".
It's useful to use more than two counter units. Connecting this line to "Gate signal input" of another
unit, another units go active counting action. Of course another units must be active in count mode
before Run signal go "H".
Command characters are ASCII data.
The delimiter of communication command is CR+LF in transmit and receive case.
Type of command
ENCS Enable to stop count by counter(CH7).
When count value of preset channel (CH7) reach to preset value,
count action automatically stopped.

４．Firmware update
For NCT08-02 it's possible to upgrade firmware via communication tools.
Here is an overview of operation.
It's possible to use USB and LAN communication.
This 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 NCT08-02.
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 NCT08-02 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 NCT08-02.
Turn on power of NCT08-02 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 off/on sequence or "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.
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．

It's possible to operate multi units synchronously.
The NCT08-02 contains 8 CH counters. You can use more than 9 channels at synchronous mode
using multi units of NCT08-02.
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.
(a) Regarding NCT08-02 when it receives data read command, it stops count and timer action for 120 ns.
This disable period is need to get latest data to latch 48 bits count data.
If you read out count data 100 times/ｓ, total disable period is 120ns × 100 = 12μｓ/s.
Disable period for each reading access is always same 120ns.
Counter and timer stops simultaneously you'd better to read data by minimum command.
When in counting pulse during "GATE" signal which comes from outside, you'll notice that counting period
is shorter than read out period.
Unless read out count values in counting period there is no error of measurement.
When in timer stop mode or counter stop mode, there is no dead time to read out count values.
(b) Notes when count multiple units at simultaneous control. (See ５．Synchronous operation by multi counter units.)
When you use multiple units at simultaneous control, you have to pay attention to error of measurement.
Concerning only read out module, measuring period is stopped for 120ns.
There for there are some errors of pulse count between units, because of the times or timing of data read out.
Example) When read out 100Times/1s for one module.
The period of counting pulse is １２μs shorter. １２０ns×１００＝１２μs.
In this case error ratio of count is １２μs／１s (0.00012%).
