8. LED Indicators

The gateway contains several different LED indicators, each of which conveys
important information about the status of the unit and connected networks.
These LEDs and their functions are summarized here.

8.1 Toshiba ASD Common Serial Port Indicators

Each Toshiba ASD common serial port RJ45 connector has two LEDs
positioned immediately above them (1 green and 1 red).
Green LED.......Indicates "drive link". Solid green when a logical connection
exists with the attached drive (i.e. the gateway is reading data
from the drive).
Red LED ..........Data write. Flashes briefly when data is written to the drive
from the point database.

8.2 RS485 Port Indicators

Each RS485 port has one red and one green LED situated next to its
respective terminal block.
Green LED.......Lights when the gateway is transmitting data on the port.
Red LED ..........Lights when the gateway is receiving data on the port (note that
this does not indicate the validity of the data with respect to a
particular protocol: only that data exists and is being detected.)

9. Configuration Switches

There are two configuration DIP switches (marked "CFG") located on the unit
near the RS232 port.
Switch #1 .........Firmware update switch. Place in "OFF" position for normal
operation, and in the "ON" position only when new firmware is
to be downloaded to the unit. Refer to section 14 for more
information.
Switch #2 .........RS232 port selection switch. When "OFF" at unit startup, the
RS232 port will act as the serial console, regardless of the
port's configuration or protocol assignment (refer to section 12
for more information on the serial console). When "ON" at unit
startup, the RS232 port carries whatever protocol (if any) was
assigned to it at configuration time. Note that the state of this
switch is only detected when the gateway boots up.
