Signal resolution output

channels
15 channels equivalent to 16-bit analog signal
16 1-bit channels equivalent to logic signal
Target signal format
1-bit signals : Use 1 logic channel or 1 analog channel.
1- to 16-bit signals : Use 1 analog channel.
17- to 32-bit signals : Use 2 analog channels.
Signals over 32 bits : Not supported.
ID trigger
When the set ID is received, a high-level pulse is output to the specified logic chan-
nel. The pulse width is 50

s if the time axis is within 5 ms/div or 1 sample if the time
axis is more than 10 ms/div.
Response time Within 200

s of CAN message reception completion
CAN message transmission
The set CAN message is transmitted to the bus for each port.
One Shot : Transmission once only
Interval
: Transmission at the set interval (10 ms to 99.99 s)
Response : Transmission when the set ID is received
Program : Transmission in the set order at the set interval (10 ms to 99.99 s)
Transmission timing depends on the start time and message transmission key.
Status indicator LEDs
Separate for ports 1 and 2
Turn green when a CAN signal with the set ID is received.
Turn red when an error occurs.
