11 Concerning the terminal commands

1.1 Overview

This manual describes the commands which are required to operate the HDMI protocol analyzer (hereafter referred to as the VA-1831) from an external computer (such as a personal computer), and it explains the transmission and reception of these commands and data. The commands and data are sent and received via the serial input/output port LAN or USB peripheral.

1.2 Communication specifications

1.2.1 LAN

Communication conditions • 10BASE-T, 100BASE-TX • UDP/IP

With a LAN connection, use a straight cable when connecting the unit through a hub. Use a crossover cable when connecting the VG and PC directly. When connecting the VG and PC directly, select the desired IP address, subnet mask and default gateway settings rather than automatically acquiring the IP addresses using the internet protocol of the PC.

Installing the USB drivers 1) When the connection to the VA-1831 has been made for the first time, the system recognizes the

VA-1831, and the “Add New Hardware Wizard” dialog box appears. Click on the [Next] button. 2) Select “Locate and install driver software (recommended)” as the search method, and click on the [Next]

button. 3) Insert the VA-1831 utility installation CD into the CD drive, check “CD drive” or “Specify location,” select

the driver inside the USB – WIN2K or USB – WIN98 folder on the disk, and click on the [Next] button. 4) Check that “ITFUSBDV.sys” has been found. Then click on [Next] to start the installation. 5) Follow the on-screen instructions.

*) When installing the driver in Windows XP, the following dialog box appears prompting authorization from Microsoft, but simply click on the [Continue] button.

1.4 Transmission control characters, data and error commands

Symbol HEX code Description STX 0x02 Start of text (command) to be transmitted ETB 0x17 End of text (data) to be transmitted (followed by data) ETX 0x03 End of text (command, data) to be transmitted ENQ 0x05 Request to start terminal mode EOT 0x04 Request to end terminal mode ACK 0x06 Positive acknowledgment character NAK 0x15 Negative acknowledgment character TRDT 0x10 Data transmission ESTS 0x11 Error status transmission BCC Any code Refer to “1.4.1 Concerning BCC (Block Check Code).”

1.4.1 Concerning BCC (Block Check Code)

BCC is used to check the validity of the command.

When commands are sent, the total data from setting command CMD1 to ETX (ETB) in the commands to be sent is calculated, and 1 byte is sent immediately after ETX (ETB). The VA-1831 now checks the data, and if the data and BCC do not match, BCC_ERR is returned from the VA-1831.

When commands are received, the total data from CMD1 to ETX (ETB) of the received command is calculated, and the validity of the data is checked using BCC of the received command and the calculated BCC.

Example of creating BCC

0x30, 0x42: When loading and sending Pixel Color Pattern

STX 0x02 CMD1 0x30 CMD2 0x42 BCC is created for these. PARM 0x01 ETX 0x03 BCC 0x64 Checksum

4


1.5 Error codes

Symbol HEX code Description PARM_SIZE_ERR 0x01 The parameter size is incorrect.

Alternatively, the data length and volume of data sent do not match (only when sequence type 5 or type 6 is used).

PARM_DATA_ERR 0x02 The parameter value is not correct. CMD_EXEC_ERR 0x03 Execution of the processing instructed by the command failed. BAD_CMD_ERR 0x04 The command is not correct. (CMD1, CMD2) BCC_ERR 0x05 The checksum does not match. CEC_SEND_HAND 0x10 Error Handling was returned for the CEC send command. CEC_SEND_BUSSF 0x11 The CEC command cannot be sent because the bus is not free. CEC_SEND_ARB 0x12 An arbitration error occurred in the CEC send command. (In the Start or

Initiator part) CEC_SEND_ACK 0x13 ACK was not returned for the CEC send command. CEC_SEND_IMP 0x14 An arbitration error occurred in the CEC send command. (In a part other than

the Start or Initiator part)
