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.
