About Terminal Commands
1.1.Overview
This manual describes the sending and receiving of the commands and data required for operating the HDMI protocol
analyzer (hereinafter referred to as the VA-1842) from an external computer (such as a PC). 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
■ Connector
RJ-45
1.2.2.USB
■ Communication conditions
- USB2.0
■ Connector
- B connector

1.3.Connection Configuration
1.3.1.LAN
■ When connected via a hub
Figure 1.3-1
■ When the PC and VA are connected directly without going through a hub
Figure 1.3-2
With a LAN connection, use a straight cable when connecting through a hub. Use a crossover
cable when connecting the VA and PC directly.
Furthermore, when connecting the PC and VA directly, set the desired IP address, subnet
mask, and default gateway settings rather than automatically acquiring the IP addresses
using the Internet protocol of the PC.
