8 VPL-EW130 3-3. Communication Procedure 3-3-1. Outline of Communication All communication between CONTROLLER (PC, etc.) and DEVICE (PROJECTOR) is performed by the command block format. Communication is started by the issue of a command at CONTROLLER and ended when the return data is sent to CONTROLLER after DEVICE receives the command.
9 VPL-EW130 3-6. Command Block Format The block format of Simpli fi ed Command for RS-232C as shown in the fi gure below . In this section, the block format for Simpli fi ed Command is explained. 3-6-1. Simpli fi ed Command [Send] The block format for sending request is shown below .
10 VPL-EW130 3-7. Packet Examples 3-7-1. Change “ASPECT” to “ZOOM” ST AR T CODE = A9h ITEM NUMBER = 0020h (ASPECT) SET/GET = 00h (SET) DA T A = 0003h (ZOOM) CHECK SUM = 23h END CODE = 9Ah Y ou will receive the packet below if the process is successfully completed.
11 VPL-EW130 4. Ethernet Ethernet corresponding model VPL-SX125, VPL-SW125 4-1. Service 4-1-1. Advertisement The advertisement service is provided to facilitate development of a PC application that can automatically detect a projector on the network. This function is achieved by broadcasting the equipment information periodically to the network.
12 VPL-EW130 4-1-2. PJ T alk By using PJ T alk, it is possible to communicate with PROJECTOR over Ethernet network. Both of set and get method are provided.
13 VPL-EW130 4-2. Communication Procedure Communication sequence is shown below . SDCP commands must be sent by CONTROLLER and PRO- JECTOR responses to it. On the other hand, SDAP commands are sent by PROJECTOR and have no response from CONTROLLER. Fig.
14 VPL-EW130 4-3. Protocols 4-3-1. SDAP This section describes the SDAP packet structure. The number in the parentheses shows byte. Fig.4-2 Packet structure 1. Header The header consists of ID (2 bytes), version (1 byte) and category (1 byte). Fig. 4-3 HEADER ID It is fi xed to “4441h”.
15 VPL-EW130 4-3-2. SDCP 1. Packet Structure The Fig. 4-5 shows SDCP packet format. The number in the parentheses shows byte. The statement for each fi eld is described bellow . Fig. 4-5 SDCP Packet Structure 2. HEADER Field The HEADER fi eld consists of VERSION and CA TEGOR Y sub fi eld shown below .
16 VPL-EW130 4. COMMAND Field There are two types of COMMAND fi eld, which are REQUEST and RESPONSE. REQUEST command is sent to the PROJECTOR from CONTROLLER. On the other hand, RESPONSE command is sent by PROJECTOR as a response to the REQUEST command.
17 VPL-EW130 (2) RESPONSE Command COMMAND fi eld for RESPONSE has three sub fi elds shown as follows. Fig. 4-8 COMMAND Filed for RESPONSE 1) RESPONSE sub fi eld The response returns the result of the request. OK (01h) Indicates that the request was executed correctly .
18 VPL-EW130 5. DA T A Field The content to be fi lled in this fi eld depends on the COMMAND fi eld. For SET Request commands, appropriate DA T A value accompanied with ITEM NO should be chosen. ITEM NO (item number) and its data is shown in the section 2-1-1.
19 VPL-EW130 0x8001 Model name Alphanumeric 12 characters If the number of characters is less than 12, the remaining digits are fi lled with 00h. 0x8002 Serial number 4 bytes n The serial number is in the range from 00000000 to 99999999.
20 VPL-EW130 7. ERROR CODE ERROR CODE has two bytes long. The table below shows the error code. Each error category is ex- plained as follows. Category Error Error Code Item Error (01**h) Invalid Item.
