Using V2-EVAL Terminal
The V2-EVAL terminal utility is a standard terminal application designed specifically to support the V2-
EVAL board. The application provides communication to the UART interface on the VNC2 device and also
provides commands to control some basic configuration functions on the V2-EVAL board. All
communication and control commands are directed to the V2-EVAL board via the onboard FT4232H USB
to quad channel serial converter.

Figure 8.2: V2-EVAL Terminal Utility Features
The V2-EVAL utility supports standard terminal commands and control functions. Pull down menus list
different UART speeds, and data settings. On the top right hand section of the software a set of check
buttons are available for controlling the V2-EVAL board. A summary of the function of each button on the
V2-EVAL terminal utility is outlined below:
„Connect’ button – Connects and disconnects the terminal utility from the UART hardware.
„Assert RTS’ checkbox – Assert the Request To Send line on the UART interface.
‘Asset DTR’ checkbox – Assert Data Terminal Ready line on the UART interface.
‘UART’ mode button – Enables full UART TX and RX operation through the V2-EVAL terminal
utility. Under the UART mode the select line of the V2-EVAL board multiplexer U4 is set to „0‟
forcing the FT4232H channel A to connect to UART interface on VNC2, as per the conditions
outlined in Table 6.1.
„Spy’ mode button – The „Spy‟ button sets the select line of the V2-EVAL board multiplexer U4 to
„1‟, allowing the VNC2 UART interface to be controlled by an external device connected to the V2-
EVAL board instead of the FT4232H, as per the conditions outlined in Table 6.1. Under this setting
a user can connect to V2-EVAL board in „Spy‟ mode via FT4232H channel C and observe VNC2
UART RX data in the terminal utility. „Spy‟ mode is a read-only UART mode. Any user data input
to the console under this mode is ignored.
‘Assert RESET’ checkbox – When checked the software will enable the RESET# input signal on
the VNC2 device. The checkbox is only available under UART mode.
‘Assert PROG’ checkbox - When checked, the software will enable the PROG# input signal on
the VNC2 device. The checkbox is only available under UART mode.
