Serial 

Adapter (Optional) 

 
Enfora P/N ADT2218 can be used to provide a standard serial interface for the MT-GL.  This adapter 
provides a standard DB9 serial interface and power to the unit.  The adapter would be used for 
loading new software onto the MT-GL.  The customer may choose to connect directly to the 12-pin 
connector serial interface pins, or order this convenient adapter from Enfora. 
 

Note:

  Only three of the pins are used; ground, serial in and serial out. 

 
 
See Figure 9 - 12-Pin Connection.
