1. Introduction
This document describes the communicati on and data formats used to control SIM2 HT300 E-LINK projector
via RS-232C port.
2. Connection
Switch off your Personal Computer and 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 HT300 E-LINK RS-232C Port is described as follows.

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.
Each packet received by the projector is acknowledged with a return code:
06: Acknowledged with no error
-
15: Acknowledged, but an error has occurred.
-
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 ls-byte of the word 0xBE is sent first, then the ms-byte 0xEF.
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
BEEF
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.

1. Send the simulated "SWITCH ON FROM STAND-BY AND SELECT SOURCE" Remote Control
keycode.
Remote Control allows Switching on from Stand-by via one of the keys "1", "2" ... "11", "12".
Send, for instance, the code relative to key "1": BEEF02060080E5490100000000.
The projector switches on and selects Input 1.
The projector returns the response code: 06 (Acknowledged with no error).
NOTE: Commands that simulate keys "1", "2" ... "11", "12" switch on the unit and select the
corresponding Source.
Command that simulate key 0 switches on the unit: the last source memorised prior to switch off is
automatically selected.
2. Send the simulated "MENU RIGHT" Remote Control keycode.
Send the packet: BEEF02060023E75A0100000000.
The OnScreen Display appers on the screen.
The projector returns the response code: 06 (Acknowledged with no error).
3. Send the "SET ASPECT ANAMORPHIC" Operation Code.
Send the packet: BEEF0206009DF5840100000000.

The Aspect Ratio changes to Anamorphic.
The projector returns the response code: 06 (Acknowledged with no error).
4. Select "INPUT 5 (COMP RGB 1) WITH YcrC b 15kHz SIGNAL"
Send the packet: BEEF0319005B0C01820800000000000008000000000000000000000000000000
Wait for the return code and add an additional delay of 40 ms.
Send the the code relative to the Key to which Input 5 has been assigned: for instance if the key is "3"
the code is: BEEF02060062E44B0100000000
6. Warnings
When the number of bytes sent to the Projector is greater than indicated for the Command (32 bytes for
Operation Packets and 13 bytes for Event Packets), excess data will be ignored.
Conversely, if number of bytes sent to the Projector is smaller than required by the Communication Protocol,
an Error Code will be returned.
Allow a time interval of at least 40 ms between the Return Code and the following Command.
