[ENG] [IOv2] Connectors and Indicators
A front panel of a NetPing IO v2 device is represented on the picture below:
On a front panel of a device, there are 2 Ethernet 10/100-BASE-TX sockets. A device can be connected to the Ethernet network using any of these connectors. The second connector may be used for plugging any network devices, including other NetPing devices.
Operation modes of a power indicator
Event | Indication |
Turning a device on. | LED blinks several times. A number of blinks depend on a length of a starting procedure and may be different for different firmware versions. Blinking does not continue more than 2 seconds and is continued until a device is internally initialized. If blinking continues for more than 2 seconds, this means that parameters of a device are reset to default values at the start (see below in this table). |
A device is turned on, there is no activity. | LED lights continuously. |
A device transmitted a package | LED blinks once for very transmitted package. |
Firmware of a device is updated. | Firmware of a device is updated in two stages:
After firmware updating, a device is rebooted. LED operates in the mode that corresponds to turning a device on. |
Parameters of a device are reset to default values. | LED blinks during the entire process of resetting values of parameters (5-10 seconds). |
LEDs 1 and 2 correspond to Eternet-ports 1 and 2 respectively. If the Ethernet connection is established on the Ethernet-port 1, LED 1 is active, if it is established on the port 2, then LED 2 is active.
Operation modes of LED 1 and LED 2
Event | Indication |
Turning on a device. | LED lights only when a connection is established on a corresponding Ethernet port. |
A device is turned on, there is no activity on a device. | LED lights continuously while a connection is established on a corresponding Ethernet port. |
A device received a package. | LED blinks once for each received package. |
Back panel of a NetPing IO v2 device is shown on the picture below:
1 – +U (power), 2 - +U (power), 3 – GND (ground), 4 – IO 1 (input/output1), 5 – IO 2 (input/output2), 6 – IO 3 (input/output3), 7 – IO 4 (input/output4), 8 – +3V3, 9 – GND (ground)
Between terminals, there is a jumper for resetting parameters of a device to default values. More detailed information can be found in the section "Resetting parameters of a device to default values"
+U – power voltage of a device +12V. The second contact +U is used to power connected sensors.
IO1 ... IO4 – are input/output lines for connecting external sensors and executive mechanisms. Each line may be configured individually as an input or an output.
