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.
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.
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".
