3Introduction OverviewThe WJ-ASC960 is a software upgrade package for the WJ-MPU955A, and can be installed on top of the WJ-MPU955A CPU. Refer to WJ-MPU955A Operating Instructions. The WJ-ASC960 software creates a distributed IP-based network platform with one or more WJ-MPU955A CPU working together to form a large-scale security sys-tem. It also offers a single CPU, not only to handle GX encoder and decoder*1 device-based digital video opera-tions, but also SX matrix*2 device-based analog video operations.GX System is high quality video imaging systems offering complete management of medium and large-scale instal-lations. The WJ-ASC960 is capable of managing up to 64 CPU units. GX System is truly network-based systems,and all the devices in the system are connected through IP-based networks.*1 GX encoder and decoder: WJ-GXE900, WJ-GXD900 series (NTSC model only)*2 SX matrix : System850 or WJ-SX650 512 x 64 Full Matrix SystemNote: GX System is supported by NTSC model only. PurposeThis document provides end users with product information about the following.• WJ-ASC960 software package• WJ-SX650 512 x 64 Full Matrix System and GX System PrecautionWe recommend that you refer all tasks related to the system installation to qualified service personnel or systeminstallers.We recommend that you make a note of all your system settings and save them. This will help you if you arerequired to change the system configuration, or if an unexpected event or failure occurs.We encourage you to obtain and read all the related documents referenced on page 4, and become familiar with theCPU unit and other related devices and software. Cautions about the Network EnvironmentGX System is IP network-based. Creating a reliable network is the key to a successful system. Please note that theencoder device sends a multicast stream (9.2 Mbps max. X 4 streams). Obtain confirmation from the network admin-istrator that this bandwidth usage will not cause a network failure.Note: MPEG2 Encoder (WJ-GXE900) and MPEG2 Decoder (WJ-GXD900) support the NTSC model only.
