4 Connecting the VS-801USB ! Always switch off the power to each device before connecting it to your VS-801USB. After connecting your VS-801USB, connect its power and then switch on the power to each device. To connect the VS-801USB as illustrated in the example in Figure 2: 1. Connect the USB devices (for example, hard drives and/or memory sticks) to the DEVICE ports. For example, a: Hard drive to port 1 Memory stick to port 4 Hard drive to port 6 Memory stick to port 8 2.
Figure 2: Connecting to the VS-801USB 4.1 Connecting to the VS-801USB via RS-232 You can connect to the VS-801USB via an RS-232 connection using, for example, a PC. Note that a null-modem adapter/connection is not required. To connect to the VS-801USB via RS-232, connect the RS-232 9-pin D-sub front panel port on the VS-801USB unit via a 9-wire straight cable (only pin 2 to pin 2, pin 3 to pin 3, and pin 5 to pin 5 need to be connected) to the RS-232 9-pin D-sub port on your PC. 4.
4.2.1 Connecting the ETHERNET Port Directly to a PC (Crossover Cable) You can connect the Ethernet port of the VS-801USB to the Ethernet port on your PC, via a crossover cable with RJ-45 connectors. i This type of connection is recommended for identifying the VS-801USB with the factory configured default IP address. After connecting the Ethernet port, configure your PC as follows: 1. Right-click the My Network Places icon on your desktop. 2. Select Properties. 3.
Figure 4: Internet Protocol (TCP/IP) Properties Window 4.2.2 Connecting the ETHERNET Port via a Network Hub (StraightThrough Cable) You can connect the Ethernet port of the VS-801USB to the Ethernet port on a network hub or network router, via a straight-through cable with RJ-45 connectors.
5 Operating the VS-801USB You can operate the VS-801USB via the front panel buttons (see Section 5.1), the REMOTE contact closure terminal block connectors (see Section 5.2), the application software (see Section 5.3) or the RC-IR3 IR remote control transmitter. 5.1 The Front Panel Buttons To select a DEVICE to switch to the HOST, press one of the eight DEVICE SELECT buttons. 5.
6 Firmware Upgrade You can upgrade the VS-801USB via the Kramer K-UPLOAD software. i The latest version of K-UPLOAD and installation instructions, as well as the application software and its user guide, can be downloaded from the Kramer Web site at www.kramerelectronics.

10 Protocol 3000 The VS-801USB can be operated using serial commands from a PC, remote controller or touch screen using the Kramer Protocol 3000. This section describes: 10.1 10.1.1 • Kramer Protocol 3000 syntax (see Section 10.1) • Kramer Protocol 3000 commands (see Section 10.2) Kramer Protocol 3000 Syntax Host Message Format Start Address (optional) Body Delimiter # Destination_id@ Message CR 10.1.1.
10.1.3 Command Terms Command A sequence of ASCII letters ('A'-'Z', 'a'-'z' and '-'). Command and parameters must be separated by at least one space. Parameters A sequence of alphanumeric ASCII characters ('0'-'9','A'-'Z','a'-'z' and some special characters for specific commands). Parameters are separated by commas. Message string Every command entered as part of a message string begins with a message starting character and ends with a message closing character.
10.1.4 Entering Commands You can directly enter all commands using a terminal with ASCII communications software, such as HyperTerminal, Hercules, etc. Connect the terminal to the serial or Ethernet port on the Kramer device. To enter CR press the Enter key. ( LF is also sent but is ignored by command parser). For commands sent from some non-Kramer controllers like Crestron, some characters require special coding (such as, /X##). Refer to the controller manual. 10.1.
