Most of the signals are extensions of circuits described in other areas of this manual. However, there
are two option select pins (see
) used to configure special modes: Option Select 1 and
Option Select 2. These pins are controlled by accessories connected to the universal connector.
outlines their functions as defined at the universal connector. In the case of the XTS
Vehicular Adapter (XTVA), Option Select 1 pin is connected to Option Select 2 pin by a diode internal
to the XTVA.
3.2.4.5 Display Module
An optional, integral, 96 pixels by 64 pixels, bit-mapped, liquid-crystal display (LCD) module is
available with either a 3 x 2 keypad with a navigational button (Model II radios) or 3 x 6 keypad with a
navigational button (Model III radios). The display module is connected to the VOCON board through
flex connector J301. The display module uses chip-on-film technology and is not field repairable.
3.2.4.5.1 7285726C01 Display Module
NOTE:
The NTN9564 VOCON kit is only compatible with the 7285726C01 display module.
The 7285726C01 display module is controlled by the Patriot IC MCU core, which programs the
display through the EIM data lines D0 - D7 (pins 9 through 16, respectively), the display chip select
line (pin 5), the EIM read/write line (pin 8), and the EIM address 0 line (pin 7) that is used to select
the register to be programmed. The Patriot IC can reset the display module through pin 6. The
display is supplied with 1.8 V (B102) to pin 17 and 3.0 V (B101) to pin 18. Display backlighting is
controlled by the Patriot IC GPIO line BL_EN signal through components R140 and Q101. The LEDs
on the display module are powered by 5 V going through resistors R101, R102, R103, and R104.
3.2.4.5.2 7285726C02 and 7285726C03 Display Modules
NOTE:
The NNTN4563 VOCON kit is compatible only with the 7285726C02 display module, while
the NNTN4819 VOCON kit is compatible only with the 7285726C03 display module. Check
the model charts for display part number compatibility with the NNTN4717 VOCON board.
The 7285726C02 and 7285726C03 display modules are controlled by the Patriot IC SPI bus, which
programs the display through the serial data line (pin 16), the serial clock line (pin 15), chip select
line (pin 5), and register select line (pin 7) that is used to select the register to be programmed. The
Patriot IC can reset the display module through pin 6. The display is supplied with GCAP II V2
regulated voltage (B101) to pins 17 and 18 or 2.9V MAKO IC regulated voltage (NNTN5567 VOCON
kit) to pins 11 and 14. Display backlighting is controlled by the Patriot IC GPIO line BL_EN signal
through components R140 and Q101. The LEDs on the display module are powered by 5 V going
through resistors R103 and R104.
