Getting Started 2 KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview 3 Overview The Kramer VP-411DS is a high performance 4x1 automatic switcher for UXGA signals and stereo audio signals. It switches any one of four UXGA sources to the UXGA output 15-pin HD computer graphics video connector, and any one of four stereo audio sources to the stereo audio output on a 3.5mm mini jack. Both the UXGA and audio IN 1 connectors are connected to output loop connectors.
Overview To achieve the best performance: Connect only good quality connection cables, thus avoiding interference, deterioration in signal quality due to poor matching, and elevated noise levels (often associated with low quality cables) Avoid interference from neighboring electrical appliances that may adversely influence signal quality and position your Kramer VP-411DS away from moisture, excessive sunlight and dust Caution – No operator-serviceable parts inside unit.

Using the VP-411DS 4x1 Automatic UXGA / Audio Switcher 5.2 Setting the PRIORITY Dipswitches Figure 4 and Table 3 describe the VP-411DS unit dipswitches and the priority setup, respectively.
Using the VP-411DS 4x1 Automatic UXGA / Audio Switcher 5.3 Connecting the REMOTE Connector The contact closure remote control pins operate in a similar way to the Input selector button. Using the contact closure remote control you can select the UXGA input or cut off the inputs. To do so, temporarily connect the required input1 pin on the REMOTE terminal block connector to the GND (Ground) pin, as Figure 5 illustrates.
Using the VP-411DS 4x1 Automatic UXGA / Audio Switcher 5.4 Connecting a PC You can connect a PC (or other controller) to the VP-411DS via the RS-232 port for remote control, and for upgrading the firmware.
Flash Memory Upgrade 6 Flash Memory Upgrade The VP-411DS firmware is located in FLASH memory, which lets you upgrade to the latest Kramer firmware version in minutes! The process involves: Downloading from the Internet (see section 6.1) Connecting the PC to the RS-232 port (see section 6.2) Upgrading Firmware (see section 6.3) 6.1 Downloading from the Internet You can download the up-to-date file1 from the Internet. To do so: 1. Go to our Web site at http://www.kramerelectronics.
Flash Memory Upgrade 6.3 Upgrading Firmware Follow these steps to upgrade the firmware: 1. Double click the desktop icon: “Flash Magic.EXE”. The Flash Magic screen appears as illustrated in Figure 7.
Flash Memory Upgrade 2. Under the “Step 1 – Communications” area, set the definitions on the screen as follows: COM Port: select the active COM port on your computer Baud Rate: 19200 Device: LPC2368 Interface: None (ISP) Oscillator Freq. (MHz): 12.000 3. Under the “Step 2 – Erase” area, check the “Erase all Flash+Code Rd Prot” box. 4. Under the “Step 3 – Hex File” area select the hex file. For example, select “VP-411DS_12.hex”. 5. Under the “Step 4 – Options” area, check the “Verify after programming” box.

Kramer Protocol 2000 9 Kramer Protocol 20001 The VP-411DS is compatible with Kramer’s Protocol 2000 (version 0.50) (below). This RS-232/RS-485 communication protocol uses four bytes of information as defined below. For RS-232, a null-modem connection between the machine and controller is used. The default data rate is 9600 baud, with no parity, 8 data bits and 1 stop bit. Note: compatible with Kramer’s Protocol 2000 does not imply that a machine includes all of the commands below.
Kramer Protocol 2000 4th BYTE: Bit 7 – Defined as 1. Bit 5 – Don’t care. OVR – Machine number override. M4…M0 – MACHINE NUMBER. Used to address machines in a system via their machine numbers. When several machines are controlled from a single serial port, they are usually configured together with each machine having an individual machine number. If the OVR bit is set, then all machine numbers will accept (implement) the command, and the addressed machine will reply.
Kramer Protocol 2000 NOTE 5 - This is a request to identify the switcher/s in the system. If the OUTPUT is set as 0, and the INPUT is set as 1 the machine will send its name. The reply is the decimal value of the INPUT and OUTPUT. For example, for a 2216, the reply to the request to send the audio machine name would be (HEX codes): 7D 96 90 81 (i.e. 128dec+ 22dec for 2nd byte, and 128dec+ 16dec for 3rd byte).
