2.2.2 MT-GL 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.
