1 LED INDICATORS OF THE iTDC/ iTDC-SR
The LEDs for indicating the status of the iTDC/iTDC-SR are located as shown on the Figure:
iTDC/iTDC-SR Board Layout. Each LED will be turned on and off as the following status of the
iTDC/iTDC-SR
LED #1 ~ LED #2 These two LEDs indicate the communication status. The LED #1 blinks while
the communication signal is normally being received from the PC. The LED
#2 blinks while the iTDC is sending the signals back to the PC after the data
being totally treated as normal. (LED #1: RXD, LED #2: TXD)
LED #3 ~ LED #6 If the TCP/IP module is installed, these LEDs indicate the status of the TCP/IP
module. LED #3: Connection Status, LED #4: 10M bps, LED #5: 100M bps,
LED #6: Communication Status
LED #7 This LED indicates the status of power supply. The LED is always on if the
iTDC is powered on.
LED #8 ~ LED #14 These LEDs indicate the status of the Output ports. The LED is turned on
while the output is activated to the output port.
LED #8: Relay #1, LED #9: Relay #2, LED #10: Relay #3, LED #11: Relay #4
LED #12: TTL #1, LED #13: TTL #2, LED #14: TTL #3
LED #15 ~ LED #21 These LEDs indicate the status of the Input ports’ signal. When the LED light
is on, it means that the signal has been input to the input port. (NC type
input device) When NO type input device is connected, the LED is on when
the sensor signal is not activated and the LED is off only when the input is
activated.
