CFA633-RDI-KS LCD Module (Hardware v2.0 / Firmware s2v1)

February 2012

POWER CONNECTION THROUGH J_RS232

The +5v and +12v power can be supplied through connector J_RS232, allowing a single cable to contain both power

and data connections. If the "Default RS-232 Pin Assignments" are selected, the five connections needed to operate the

module are all on a single column of pins on J_RS232, which allows a single 0.1-inch spacing 5-conductor cable to

connect between the CFA633-RDI-KS and your embedded system.

JP10 and JP13 are open by default. To enable +5 v to be supplied through J_RS232, close JP13. To allow +12 v to be

supplied through J_RS232, close JP10.

Modification by You

To close JP10 and JP13, see Jumper Locations and Functions (All Interfaces) (Pg. 17) for jumper locations and

functions.

Modification by Crystalfontz

Crystalfontz can configure the modules so they will be ready to use in your application without modification by you. We

do this by closing JP10 and JP13. For information, please contact technical support (call +1-888-206-9720 or email

techinfo@crystalfontz.com). We will provide you with a semi-custom part number. A minimum order quantity may apply.

NOTE

Do not connect high power fans to the module when +12v is supplied through J_RS232/JP10. Total

fan current must be less than 500 mA if +12v is supplied through J_RS232/JP10. When using high

power fans, supply the +12v through the J_PWR connector.
