F.7 TFTIFS15 CONNECTOR AND SOLDER LINKS
Table F9 gives the pin assignments of the TFTIFS15 display connector.
The TFTIFS15 has one solder link. LK1 can be set to one of two positions. In the 1-2
position the display’s +5V power is sourced from the TP400 via the 40-way ribbon
cable. In the 2-3 position the display’s +5V supply is sourced from connector J4.
Because the Hosiden display may require significant current, DSP Design
recommend that the display is powered via J4. Pin assignments of connector J4 are
given in Table F8.
