When switch is "OFF" in contrast, the corresponding bit is "1". When "1" is output to a relevant bit, the corresponding LED comes on. When "0" is output to the bit, in contrast, the LED goes out. CAUTION Take care not to short the outputs to digital ground as this may cause a fault. Counter signals and Control signals Connection Counter signals and Control signals Connection The following sections show examples of how to connect counter I/O signals, and other control I/O signals (external trigger input signals, sampling clock input signals, etc.). All the counter I/O signals and control signals are TTL level signals. About the counter input control signal Counter Gate Control Input (refer to the user’s manual - chapter 3 Connector Pin Assignment) acts as an input that validate or invalidate the input of an external clock for the counter. This function enables the control of an external clock input for the counter. The external clock for the counter is effective when input is "High” and invalid when input is "Low". If unconnected, it is a pull-up in this product and remains "High". Therefore the external clock for the counter is effective when the counter gate control input is not connected. CAUTION - Do not short the output signals to analog ground, digital ground, and/or power line. Doing so may damage the product. - If connected to each output, a pull-up resistor must be about 10kΩ to pull up with a 5V power source. - Each input accepts 5V TTL signals.
