DeviceMaster LEDs
DeviceMaster LEDs
The DeviceMaster has network and port LEDs to indicate status.
Port LEDs Port LEDs are amber and green on 4, 8, 16, and 32-port. The 1-port and 2-port
models do not have port LEDS. After a port has been opened in RS-232 mode, an
amber LED means that there is link between the port and the serial device. After
a port has been opened in RS-422 or RS-485 mode, an amber LED means that data
is receiving data. A green port LED indicates transmit activity.
Network and Device
LEDs The LEDs indicate that the default DeviceMaster application, SocketServer is
running or after driver installation, that the NS-Link driver loads. If you have
loaded PortVision DX, you can check the DeviceMaster status on-line.
