5811 Datasheet, PDF (2/11 Pages) Allegro MicroSystems – BiMOS II 12-BIT SERIAL-INPUT, LATCHED SOURCE DRIVERS

What You Will Need
To start using the application board you will need:
• VM-1 Control Module (5800 or 5801) with language ROM (5803)
• 8 to 30V 300mA unregulated DC power supply
• An RS232 serial lead to connect the 5811 to your host computer. Use a lead that would be used to connect
two PCs together (a "Null Modem" cable)
• A PC running terminal emulation software such as Hyperterminal or Tera Term Pro.
• The VM-1 and Venom-SC manual set
• Optionally a QVGA card (5809) or ethernet card (5810)
Serial Ports
The RS232 level shifter ICs are socketed. Leave them in if you wish to use standard RS232 voltage levels
(normal with serial cables such as links to a PC). If you need to use the logic-level signals (typically for
internal connection to small PCB modules and ICs), remove the RS-232 IC and use the serial channels on
JP4.
