HOST COMMUNICATIONS
CFA-633 communicates with host using RS-232 interface. port settings 19200 baud, data bits, parity, stop factory default. speed 115200 baud under software control (see command Baud Rate (Pg. 36)).
PACKET STRUCTURE
communication between CFA-633 host takes place form simple robust checked packet. packet format allows very reliable communications between CFA-633 host without traditional problems that occur stream-based serial communication (such having send data inefficient ASCII format, "escape" certain "control characters", losing sync character corrupted, missing, inserted). packets have following structure: <type><data_length><data><CRC>

ABOUT HANDSHAKING
nature CFA-633's packets makes unnecessary implement traditional hardware software handshaking. host should wait corresponding acknowledge packet from CFA-633 before sending next command packet. CFA-633 will respond packets within host software should stop waiting retry packet CFA-633 fails respond within host software should report error packet acknowledged after several retries. This situation indicates hardware problem-for example, disconnected cable. Please note that some operating systems introduce delays between when data arrives physical port from CFA-633 until available user program. this case, host program have increase timeout window account additional overhead operating system. CFA-633 configured send several types report packets along with regular acknowledge packets. host should able buffer several incoming packets must guarantee that process remove packets from input buffer faster than packets arrive given baud rate reporting configuration CFA-633. modern using reasonably efficient software, this requirement will pose challenge. report packets sent asynchronously with respect command packets received from host. host should assume that first packet received after sends command acknowledge packet that command. host should inspect type field incoming packets process them accordingly.
REPORT CODES
CFA-633 configured report three items. CFA-633 sends reports automatically when data becomes available. Reports sent response particular packet received from host. three report types are:
0x80: Activity

Power Fail-Safe
combination CFA-633 used part active cooling system. instance, fans system slowed down reduce noise when system idle when ambient temperature low, sped when system under heavy load ambient temperature high. Since there very large number ways control speed fans (thresholds, thermostat, proportional, PID, multiple temperature sensors "contributing" speed several fans there foresee particular requirements your system include algorithm CFA-633's firmware that would optimal your application. Varying speeds under host software control gives ultimate flexibility system design would typically have fatal flaw: host software hardware failure could cause cooling system fail. fans were slow speed when host software failed, system components damaged inadequate cooling. power fail-safe command allows host control fans without compromising safety. When control software activates, should fans that under control fail-safe mode with appropriate timeout value. reason host fails update power fans before timeout expires, fans previously failsafe mode will forced 100% power. #define FAN_1 0x01 #define FAN_2 0x02 #define FAN_3 0x04 #define FAN_4 0x08

CFA-633 controls speed using PWM. Using turns power quickly change average power delivered fan. CFA-633 uses approximately repetition rate. fan's tachometer output only valid power applied fan. Most fans produce valid tachometer output very quickly after been turned back some fans take time after being turned before their tachometer output valid. This command allows variable-length delay after been turned before CFA-633 will recognize transitions tachometer line. delay specified counts, each count being nominally 552.5 long (1/100 period repetition rate).

practice, most fans will need delay changed from default length count. fan's tachometer output stable when setting other than 100%, simply increase delay until reading stable. Typically would start delay count 100, reduce until problem reappears, then slightly increase delay count give some margin.

CARE HANDLING PRECAUTIONS
optimum operation CFA633-TMC-KS prolong life, please follow precautions described below.
ELECTROSTATIC DISCHARGE (ESD)
Please industry standard antistatic precautions would other such expansion cards motherboards. Ground your body, work surfaces, equipment.
DESIGN MOUNTING
protect polarizer from damage, CFA633-TMC-KS ships with protective film over glass. Please peel protective film slowly. Peeling protective film abruptly generate static electricity. using Crystalfontz overlay, place transparent plate (for example, acrylic, polycarbonate, glass) front CFA633-TMC-KS, leaving small between plate display surface. HP-92 Lexan, which readily available works well. disassemble modify CFA633-TMC-KS. Solder only terminals. reverse polarity power supply connections. Reversing polarity will immediately ruin module.
AVOID SHOCK, IMPACT, TORQUE, TENSION
expose CFA633-TMC-KS strong mechanical shock, impact, torque, tension. drop, toss, bend, twist CFA633-TMC-KS. place weight pressure CFA633-TMC-KS.
PANEL BREAKS
panel breaks, careful liquid crystal fluid your mouth eyes. liquid crystal fluid touches your skin, clothes, work surface, wash immediately using soap plenty water. panel.
CLEANING
clean front LCD, standard household glass cleaner works well. Gently wipe with nonabrasive soft cloth. CFA633-TMC-KS without Crystalfontz overlay: exposed surface "glass" actually front polarizer laminated glass. polarizer made fairly soft plastic easily scratched damaged. polarizer will eventually become hazy take great care when cleaning Long contact with moisture (from condensation cleaning) permanently spot stain polarizer.

CFA633-TMC-KS Serial Module Data Sheet Hardware v1.5a Firmware k1.9 Data Sheet k1.9c Page
OPERATION
Your circuit should designed protect CFA633-TMC-KS from power supply transients. Observe operating temperature limitations: minimum maximum 50°C with minimal fluctuation. Operation outside these limits shorten life and/or harm display. lower temperatures this range, response time delayed. higher temperatures this range, display becomes dark. (You need adjust contrast.) Operate away from dust, moisture, direct sunlight.
STORAGE
Store ESD-approved container away from dust, moisture, direct sunlight. -10°C minimum, 60°C maximum with minimal fluctuation. Rapid temperature changes cause moisture form, resulting permanent damage. allow weight placed CFA633-TMC-KSs while they storage.
