Introduction This document describes the communication and data formats used to control SIM2 C3X LINK projector via RS-232C port. 2. Connection Switch off the Personal Computer the Projector before connecting RS 232C cable. Use a standard serial cable with 9 pin female to the Personal Computer and 9 pin male to the Projector: pin 2 connects to pin2, pin 3 to pin 3 and pin 5 to pin 5. SIM2 C3X LINK RS-232C Port is described as follows. SIM 2 C3X LINK RS-232C Control Port: D-SUB 9-pin (female) Pin No Signal Definition 1 N/A Not used 2 TD Transmit data 3 RD Receive data 5 \ O O O O O 1 4 N/A Not used 9\ OOOO 6 5 GND Ground 6 N/A Not used 7 N/A Not used 8 N/A Not used 9 N/A Not used Switch on the Personal Computer and, after start up, switch on the Projector. Load a suitable communication software onto your Personal Computer, and set the Serial Port Parameters as shown below. Communication Parameters: Parameter Value Transfer Rate 19200 bps Data Bits 8 Parity Bit None Stop Bit 1 Flow Control None Set Send Mode and Read Mode to HEX. 3 SIM2 C3X LINK RS-232C CONTROL SPECIFICATIONS 3. Communication Protocol The communication protocol is packet oriented. Packets consists of Header and Payload. There are two types of packets: Event and Operation. The packet header size is fixed (7 bytes), while the packet payload type and content varies based on the type of packet: Event payload size is 6 bytes, while Operation payload size is 25 bytes. The entire packet size is variable, being the sum of the fixed-size packet header and variable-sized packet payload: Event packet size is 13 bytes and Operation packet size is 32 bytes. Header All Packets use the same Packet Header format. The Packet Header size is fixed at seven bytes. 1 2 3 4 5 6 EF Packet Type Packet Payload Size Packet Checksum (CRC) 0xEFBE is a fixed value that is used to insure packet alignment if there are partial packets received or byte lost. The least-significant byte of the word (be) is sent first, then the most-significant-byte (ef) . The Packet Type is a number (a byte in length) that defines the type of data in the packet. The Packet Payload Size is a number (two bytes) that defines the size of the payload portion of the packet. For a given Packet Type, Packet Size is fixed. The Packet Checksum (two bytes) is the CRC value for the entire packet (Header and Payload). Payload The packet payload format depends on the packet type. The Event packet payload size is 6 bytes, while the Operation packet payload size is 25 bytes.
