     7Gateworks has two models of JTAG programmers:
     8
     9GW16042 which contains a 14-pin, 0.1" connector for Avila/Cambria/Laguna(GW2387, GW2388, GW2391) boards.
     10
     11GW16099 which contains a 10-pin, 0.05" connector for Laguna(GW2380, GW2382, GW2383)/Ventana/Newport boards.

     13Both of these programmers uses an FTDI FT2232D which has two general purpose 8-bit ports.  The 1st port is configured for JTAG and utilizes the FTDI MPSSE engine. The 2nd port is configured for serial and used for the Serial Console.
