5 Connecting the VS-401USB ! Always switch off the power to each device before connecting it to your VS-401USB. After connecting your VS-401USB, connect its power and then switch on the power to each device. To connect the VS-401USB 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 2 Smart phone to port 3 Memory stick to port 4 2.
Figure 2: Connecting to the VS-401USB 5.1 Connecting a PC You can connect to the VS-401USB 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-401USB via RS-232, connect the RS-232 9-pin D-sub rear panel port on the VS-401USB 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.
6 Operating the VS-401USB You can operate the VS-401USB via the front panel buttons by pressing one of the four DEVICE SELECT buttons to select a device to switch to the HOST. You can also use the application software (see Section 6.1) or the RC-IR3 IR remote control transmitter to operate the VS-401USB. 6.1 The Application Software Use the K-SINGLE control application software to control the VS-401USB via the Ethernet or RS-232 9-pin D-sub.
7 Firmware Upgrade You can upgrade the VS-401USB 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.

11 Protocol 3000 The VS-401USB can be operated using serial commands from a PC, remote controller or touch screen using the Kramer Protocol 3000. This section describes: 11.1 • Kramer Protocol 3000 syntax (see Section 11.1) • Kramer Protocol 3000 commands (see Section 11.2) Kramer Protocol 3000 Syntax 11.1.1 Host Message Format Start Address (optional) Body Delimiter # Destination_id@ Message CR 11.1.1.
11.1.3 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.
11.1.4 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. 11.1.
