Sony NXLIP55 User Manual (NXL-IP55 Operations Manual) - Page 3

Overview Features The NXL-IP55 IP Live Production Unit is an IP transmission device that allows upstream and downstream transmission of HD video signals, audio signals, and various control signals with low latency of less than one field (excluding network delays). Using the unit allows you to configure a live production system over a network. Network synchronization Devices can be synchronized via a network. Low-latency video transmission is made possible during live production by eliminating the need for synchronization via a frame synchronizer. Various transmission signals Up to four video channels are available for transmission with up to three in the same direction. Ten audio channels (five pairs) are available for transmission with eight in the same direction. Eight GPIO channels, six tally channels, and one channel for a synchronization signal are also available. Note The content of this document applies to firmware version V1.10. NXL-IP55 units with different firmware version cannot be connected together. You can check the firmware version in [Device Information] on the [Status] page in the Web menu. If using an NXL-IP55 unit with a different firmware version, contact your store or point of purchase. Transmittable Signals Video signals 1080/50i, 1080/59.94i, 720/50P, 720/59.94P, 1080/25PsF, 1080/29.97PsF Can transfer up to four channels of HD SDI signals, with up to three in the same direction. 1080/50P, 1080/59.94P Can transfer total of two channels using Dual Link SDI, with one in each direction. Note Signals with different formats cannot be transferred at the same time. Audio signals Up to five pairs of two channels (48 kHz/24 bit) are available for audio signals, analog audio signals, and intercom signals embedded on HD-SDI signals (up to eight channels in the same direction). Notes • HD-SDI embedded audio can be transmitted on Ch1 to Ch2 or Ch1 to Ch4. The audio will not be transmitted on Ch5 and above. Metadata attached to HD-SDI signals cannot be transmitted. • When transferring Dual Link SDI, audio signals can be embedded in Link-A only. Tally signals Three channels each are available for R tally signals and G tally signals. However, the transmission direction for all channels is the same. GPIO Eight channels are available. The transmission direction can be switched by using four channels as one group. Supported Networks Use this unit in a network that meets the following specifications. Check whether the network you want to use fulfills these requirements by performing a network test in the web menu before use. Note The network test only displays the status of the area that can be detected at the moment the test is executed. It does not guarantee the quality of the network or the operation of this unit. Network connected to the MAIN connector This network connects to the unit's MAIN connector and transmits video signals and control signals. The requirements for this network are as follows. • The network is a secure LAN independent from other systems and networks. It cannot be used as a WAN or Internet line. • Use a Layer 2 switch with 5 or less levels. Routers cannot be used. • Interface: 1000BASE-T • MTU: 1500 bytes or higher, no fragments • Latency: 10 ms or less without fluctuation (one way) • Bandwidth: 600 Mbps or more maintained Network connected to the CONTROL connector This network connects to the unit's CONTROL connector and connects the computer used to configure this unit. • Interface: 100BASE-TX 3 Overview
