Connecting the VP-81K 8x1 UXGA / Audio Switcher 6.2 Controlling via RS-232 You can connect a PC (or other controller) to the VP-81K via the RS-232 port for remote control, and for upgrading the firmware. To connect a PC to a VP-81K unit, using the Null-modem adapter provided...
Connecting the VP-81K 8x1 UXGA / Audio Switcher 6.3 Controlling via RS-485 You can control a VP- K unit via an RS-485 controller, for example, a PC (equipped with an RS-485 interface) or a Master Programmable Remote Control system such as the Kramer RC-3000.
6.4.1 Connecting the ETHERNET Port Directly to a PC (Crossover Cable) You can connect the Ethernet port of the VP-81K to the Ethernet port on your PC, via a crossover cable with RJ-45 connectors. This type of connection is recommended for identifying the VP-81K...
Figure 8: Internet Protocol (TCP/IP) Properties Window 6.4.2 Connecting via a Straight-Through Cable You can connect the ETHERNET of the VP-81K to the Ethernet port on a network hub or network router, via a straight-through cable with RJ-45 connectors. 6.4.3...
Connecting the VP-81K 8x1 UXGA / Audio Switcher 2. Select the method to connect to the Ethernet port of the VP-81K. Select: Ethernet, if you know the IP address number or the machine name. The default name for the machine is KRAMER_XXXX Serial, if you are connected via a serial port 3.
Connecting the VP-81K 8x1 UXGA / Audio Switcher 6.4.4 Controlling via the Embedded Web Pages The embedded Web page can be used to remotely operate the VP-81K via the Ethernet. Before you use the embedded Web pages to control the VP-81K via the Ethernet, check that the Java™...

Connecting the VP-81K 8x1 UXGA / Audio Switcher 6.6 Cascading Machines You can cascade up to eight VP-81K units with control from a PC or serial controller (see Figure 14). To cascade up to eight individual VP-81K units via RS-485, do the following: 1.
(refer to the RC-IR2 user manual) or the infrared remote Transmitter extension cable transmitter Powering up VP-81K unit, recalls the previous settings (that is, the state of the unit when it was powered down) from the non-volatile memory. 7.1 Using the Front Panel INPUT SELECTOR Buttons Table 5 describes the INPUT SELECTOR button illumination definitions.
Other switching operations are performed manually. 7.3 Using the Audio-Follow-Video / Breakaway Modes By default, the VP-81K switches in true audio-follow-video mode in which all operations relate to both the video and audio. Both the VIDEO and the AUDIO buttons illuminate in this mode.
8.2 Connecting the PC to the RS-232 Port Before installing the latest Kramer firmware version on a VP-81K unit, connect the RS-232 9-pin D-sub rear panel port on the VP-81K unit to the Null-modem adapter and connect the Null-modem adapter with a 9-wire flat cable to the RS-232 9-pin D-sub COM port on your PC (see section 6.2).
8.3 Upgrading Firmware To upgrade the firmware, do the following: 1. Double click the desktop icon: “ FlashLoader” . 2. Connect the power on the VP-81K unit and switch it ON. 3. Set the appropriate COM port. The following screen appears: Figure 15: FlashLoader Window 4.
Wait for completion of the upgrade procedure. The new firmware version appears in the INPUT STATUS 7-segment Display. Figure 16: Flash Upgrade Process 6. If required, disconnect the RS-232 rear panel port on the VP-81K unit from the Null-modem adapter.
10 Table of ASCII Codes for Serial Communication (Protocol 3000) Table 7 lists the ASCII values to switch an input to an output for a single VP-81K machine. For more detailed information, see Protocol 3000 (section 12.2). Table 7: VP-81K Codes for Protocol 3000...
Kramer Protocol 12 Kramer Protocol By default, the VP-81K is set to protocol 3000 (see section 12.2) but is also compatible with Kramer’ s Protocol 2000 (see section 12.3). Section 12.1 describes how to switch between protocol 3000 and protocol 2000.
Kramer Protocol 12.2 Kramer Protocol 3000 This RS-232/RS-485 communication protocol lets you control the machine from any standard terminal software (for example, Windows® HyperTerminal Application). 12.2.1 Protocol 3000 Syntax Host message format: Start Address (optional) Body Delimiter Destination_id@ message Simple command (commands string with only one command without...
Design note: transparent supporting for protocol 2000 will be implemented by switch protocol command from protocol 3000 to protocol 2000, in protocol 2000 there is already such a command to switch protocol to ASCII protocol (#56 : H38 H80 H83 H81). KRAMER: SIMPLE CREATIVE TECHNOLOGY...
