Your VP-8x4 8x4 VGA / UXGA Matrix Switcher 4.1 Using the IR Transmitter You can use the RC-IR2 IR transmitter to control the machine via the built-in IR receiver on the front panel or, instead, via an optional external IR receiver1. The external IR receiver can be located 15 meters away from the machine. This distance can be extended to up to 60 meters when used with three extension cables2.
Installing the VP-8x4 in a Rack 5 Installing the VP-8x4 in a Rack This section describes how to install the VP-8x4 in a rack.
Connecting the VP-8x4 8x4 VGA / UXGA Matrix Switcher 6 Connecting the VP-8x4 8x4 VGA / UXGA Matrix Switcher This section describes how to: Connect the VP-8x4 rear panel (see section 6.1) Connect the VP-8x4 to a controlling device via RS-232 (see section 6.2), RS-485 (see section 6.3) and/or the Ethernet (see section 6.4) Set the dipswitches (see section 6.5) Connect several VP-8x4 machines (see section 6.6) 6.

Connecting the VP-8x4 8x4 VGA / UXGA Matrix Switcher 6.2 Controlling via RS-232 (for example, using a PC) To connect a PC to the VP-8x4 unit, using the null-modem adapter provided with the machine (recommended): Connect the null-modem adapter to the RS-232 9-pin D-sub port on the rear panel of the Master VP-8x4.
Connecting the VP-8x4 8x4 VGA / UXGA Matrix Switcher Figure 5: Controlling via RS-485 (for example, using an RC-3000) 6.4 Control Configuration via the Ethernet Port To connect and configure the Ethernet port of the VP-8x4, refer to the ETHERNET Configuration (Lantronix) GUIDE on our Web site: http://www.kramerelectronics.com. 6.5 Setting the DIP-switches By default, all dipswitches are set to OFF.
Connecting the VP-8x4 8x4 VGA / UXGA Matrix Switcher 6.5.1 Setting the Delay You can achieve clean transitions when switching between non-genlocked sources by setting the delay time—ranging from 0 sec to 3.5 sec1—via the DELAY DIP-switches, as Table 5 defines. The VP-8x4 unit is shipped (its factory default state) with no delay, that is, the DELAY DIP-switches are set up for a 0 sec delay. The delay time is the period where the output will be forced to black when switching between inputs.
Connecting the VP-8x4 8x4 VGA / UXGA Matrix Switcher 6.6 Cascading Machines You can cascade up to 16 VP-8x4 units with control from a PC or serial controller (see Figure 7). To cascade up to 16 individual VP-8x4 units via RS-485, do the following: 1. Connect the VGA/UXGA sources and acceptors, as section 6.1 describes. 2. Connect the RS-232 port1 on the first VP-8x4 unit to the PC using the null-modem adapter provided with the machine (recommended), as section 6.2 describes. 3.

Operating the VP-4x8 8x4 VGA / UXGA Matrix Switcher 7 Operating the VP-4x8 8x4 VGA / UXGA Matrix Switcher You can operate your VP-8x4 via: The front panel buttons RS-232/RS-485 serial commands transmitted by a touch screen system, PC, or other serial controller The Kramer RC-IR Infrared Remote Control Transmitter The Ethernet 7.
Operating the VP-4x8 8x4 VGA / UXGA Matrix Switcher 7.2 Confirming Settings You can choose to work in the At Once or the Confirm mode.
Operating the VP-4x8 8x4 VGA / UXGA Matrix Switcher To confirm several actions (in the Confirm mode), do the following: 1. Press each OUT-IN combination in sequence. The corresponding 7-segment Display blinks. The TAKE button also blinks. 2. Press the blinking TAKE button to confirm all the actions. The corresponding 7-segment Display no longer blinks. The TAKE button illuminates. 7.
Operating the VP-4x8 8x4 VGA / UXGA Matrix Switcher Tip: If you cannot remember which of the 12 input/output configurations is the one that you want, set the VP-8x4 to the Confirm mode and manually scan all the input/output configurations until you locate it. 7.3.3 Deleting an Input/Output Configuration To delete an input/output configuration, do the following: 1. Press the STO and RCL buttons simultaneously. Both the STO and RCL buttons blink. 2. Press the appropriate INPUT/OUTPUT button.
Flash Memory Upgrade 8 Flash Memory Upgrade The VP-8x4 firmware is located in FLASH memory, which lets you upgrade to the latest Kramer firmware version in minutes! Note: The firmware update should be carried out by skilled technical personnel. Failure to update correctly can cause machine malfunction. The process involves: Downloading from the Internet (see section 8.1) Connecting the PC to the RS-232 port (see section 8.2) Upgrading Firmware (see section 8.3) 8.

Kramer Protocol 2000 11 Kramer Protocol 20001 The VP-8x4 is compatible with Kramer’s Protocol 20002, version 0.50. 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.
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 3 - SETUP # 0 is the present setting. SETUP # 1 and higher are the settings saved in the switcher' s memory, (i.e. those used for Store and Recall). NOTE 4 - The reply to a "REQUEST" instruction is as follows: the same instruction and INPUT codes as were sent are returned, and the OUTPUT is assigned the value of the requested parameter. The replies to instructions 10 and 11 are as per the definitions in instructions 7 and 8 respectively.
