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. 
 

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.  

 

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.) 

 
 

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.
