Appendix K : Uart Module - AVE VSI-Pro Max Operation Manual

USING THE UART MODULE APPENDIX K
Using UART Module (UART daughter board) with VSI-Pro Max (R17 or Higher)
UART module is daughter board for special communication of the VSI-Pro Max. When the UART Module has been
installed into the J4 connector on the VSI-Pro Max Printed Circuit Board, the VSI-Pro Max can receive the special data
format ; that is 7 data bits and no parity and fully emulate the 16550 UART commonly used in PCs.

Figure 220: VSI-Pro Max Silkscreen
The VSI-Pro Max automatically recognizes the UART daughter board is installed and then uses this 16550 Compatible
UART for the Register Port and all Selections. If VSI-Pro Max cannot communicate with the UART daughter board then
this message will appear on the screen " UART DAUGHTER BOARD NOT INSTALLED".
The VSI-Pro Max combined with the UART daughter board can interface to a device which can transmit the specific
format data; that is data bits is 7 bits and no parity. Access the Main Menu, select GENERIC or specific driver in the
"REGISTER SELECT" menu then exit to the Main Menu. Press the "Up" or "Down" buttons to move the cursor to
"Communication" menu then set a PARITY sub menu is NONE and set DATA BITS sub menu is 7. If VSI-Pro Max cannot
communicate with the daughter board, This message will appear on the screen." UART DAUGHTER BOARD NOT
INSTALLED ".
NOTE: This PCB must be installed at the factory for VSI-Pro Max PCB F4L6 or earlier due to internal modification
required. On this version the "Register Data LED" will be disabled. For VSI-Pro Max PCB F5 or higher the user can install
this PCB by just plugging in the connector and the "Register Data LED" will not be disabled. Jumper Settings; JP1 OFF,
JP3 OFF, JP4 OFF, JP5 ON, JP11 ON. RTS Alarm Input or Handshaking is not available when using the UART PCB.
See Appendix S Page 98 for additional jumper information.
