Case Styles 

 
The  ES-U-xxxx-x  converters  are  available  in  Plastic,  Metal  and  Metal  Rackmount  enclosure  styles.  All 
units can be used on a desktop with the self-adhesive feet provided. 
 

 

Plastic  case  desktop  converters  are  supplied  with  USB  cable  (except  ES-U-1001-A  and  ES-U-
1002-A) and a power adapter localised to country of sale (when required depending on model). 

 

Metal case converters are supplied with wall mounting hardware, USB cable and power adapter 
with plug localised to country of sale (when required depending on model). 

 

Metal  rack  mount  converters  are  supplied  with  rack  mounting  hardware,  USB  cable  and  power 
cable or power adapter localised to country of sale. 

 
Transmit and receive LEDs for each port are included on the front or top panel of the enclosure, to show 
when data is being transmitted or received by the associated port. A power LED is also included (on units 
with metal enclosures) to show that the converter is receiving power. 
 
Note  that  enclosure  colour  may  vary  from  the  photos  shown.  Some  models  with  metal  enclosures  are 
changing to a black colour
