CNMSX Indicators
A number of indicators are provided on the front panel of the CNMSX. Refer to the
description of each below.
PWR
This LED illuminates when the unit is connected to and receives power from an AC
outlet.
NET
This LED illuminates when the central processing unit (CNXPU) is processing or
communicating with system hardware (i.e., button pressed at local panel or network
panel, data being sent out serial port, or permanent memory image being created).
ERR
This LED illuminates when an error condition is detected by the CNXPU. This may
be the result of hardware or software failure, hardware incompatibility with software
definitions, or a programming error. To decipher content, examine the message
available from the menu function buttons.
NOTE:
The next four LEDs are active only if the DPA Expansion Card (which is
field installed) occupies the DPA slot.
TXD (LAN)
This LED illuminates during transmission of ethernet data from the DPA slot.
RXD (LAN)
This LED illuminates during reception of ethernet data by the DPA slot.
LNK (LAN)
This LED illuminates when there are attachements to the ethernet network.
ERR (LAN)
This LED illuminates when an ethernet protocol error is detected.
NOTE:
The remaining LEDs mentioned after this note are available on the PRO
configuration, but not available on the AV configuration.
COM TX (A - F)
These LEDs illuminate during transmission of data to serial devices attached to
respective COM ports.
COM RX (A - F)
These LEDs illuminate during reception of data from serial devices attached to
respective COM ports.
COM RTS (A - F)
These LEDs illuminate to reflect the state of RTS (A - F). An illuminated LED means
that the RTS line is high. If no handshaking is specified, the RTS line will be high and
therefore, the associated LED is also high. When RTS flow control is enabled, RTS
indicates the unit is ready to receive data from serial devices attached to respective
COM ports.
