1. Introduction
This document describes the communication and data formats used to control SIM2 C3X LITE projector via
RS-232C port.
2. Connection
Switch off the Personal Computer and 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 LITE RS-232C Port is described as follows.
SIM 2 C3X LITE RS-232C Control Port:
D-SUB 9-pin
(female)
5 1
9 6
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. 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.
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).
0 1 2 3 4 5 6

Packet Type Packet Payload Size Packet Checksum (CRC)
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.
