4 Installing in a Rack This section provides instructions for rack mounting the unit.
5 Connecting a Single VP-1608 i Always switch off the power to each device before connecting it to your VP-1608. After connecting your VP-1608, connect its power and then switch on the power to each device. To connect a single VP-1608 16x8 RGBHV/Balanced Audio Matrix as illustrated in Figure 4, do the following: To connect up to 8 VP-1608 units to a PC or other RS-232/RS-485 controller (see Section 6). 1. Connect up to 16 RGBHV sources (such as RGBHV graphics sources) to the RGBHV INPUT BNC connectors.
Figure 4: Connecting the VP-1608 10 VP-1608 - Connecting a Single VP-1608
5.1 Connecting a Balanced/Unbalanced Stereo Audio Input/Output This section illustrates how to wire: • A balanced stereo audio connection, see Figure 5 • An unbalanced stereo audio input connection, see Figure 6 • An unbalanced stereo audio output connection, see Figure 7 Figure 5: Balanced Stereo Audio Connection 5.
To connect a device with a RS-485 port to the VP-1608: • Connect the A (+) pin on the RS-485 port of the PC to the A (+) pin on the RS-485 port on the rear panel of the VP-1608 • Connect the B (–) pin on the RS-485 port of the PC to the B (–) pin on the RS-485 port on the rear panel of the VP-1608 • Connect the G pin on the RS-485 port of the PC to the G pin on the RS-485 port on the rear panel of the VP-1608 5.
5.5 Setting the DELAY DIP-Switches To achieve clean transitions when switching between non-genlocked sources, set the delay time—ranging from 0sec to 3.5sec in increments of 0.5sec—via the DELAY DIP-switches, as shown in the following table. The VP-1608 unit is shipped from the factory set with no delay (0sec). Sec DIP 1 DIP 2 DIP 3 DIP 4 0 OFF OFF OFF OFF 0.5 OFF OFF OFF ON 1.0 OFF OFF ON OFF 1.5 OFF OFF ON ON 2.0 OFF ON OFF OFF 2.5 OFF ON OFF ON 3.
6 Connecting Multiple VP-1608 Units You can connect up to eight single VP-1608 units from a PC or serial controller via RS-232 and RS-485 (see Section 6.1), or up to seven single VP-1608 units via RS-485 (see Section 6.2). To connect a single VP-1608 unit to a PC or other RS-232 controller, see Section 5.2. 6.
Figure 8: Control Configuration via RS-232 and RS-485 6.2 Connecting via an RS-485 Controller To connect up to seven single VP-1608 units via an RS-485 controller, for example, a PC (equipped with an RS-485 interface), do the following: i Always switch off the power to each device before connecting it to your VP-1608. After connecting your VP-1608, connect its power and then switch on the power to each device. 1.
2. On each VP-1608 unit, set the MACHINE # DIP-switches, as required. For example, set the first VP-1608 unit to MACHINE # 2, the second VP-1608 unit to MACHINE # 3, and so on, up to MACHINE # 8 for the seventh VP-1608 unit (see Section 5.3). 3. Terminate the RS-485 line on both the PC and on the last VP-1608 unit (set DIP 4 to ON). 4.
7 Operating Your VP-1608 16x8 RGBHV/Balanced Audio Matrix This section describes how to operate the VP-1608. The section includes: 7.1 • Choosing the Audio-Follow-Video or Breakaway option (see Section 7.1) • Switching OUT-IN combinations (see Section 7.2) • Confirming settings (see Section 7.3) • Storing/recalling input/output configurations (see Section 7.4) • Adjusting the audio gain control (see section 7.5) • Locking and unlocking the front panel (see Section 7.
7.1.1 Setting the Audio-Follow-Video To set the audio-follow-video (AFV) option, press the AFV button: • If the AUDIO and VIDEO configurations are the same, the AFV button illuminates. The audio follows the video • If the AUDIO differs from the VIDEO, the TAKE and the AUDIO buttons flash. Also, the audio outputs in the INPUT STATUS 7-segment display that are changed, flash (warning that you are about to modify the audio configuration for AFV operation). Press the TAKE button to confirm the modification.
7.3 Confirming Settings Choose to work in the AT ONCE or the CONFIRM mode, as explained in Section 7.3.1. When the VP-1608 operates in the AT ONCE mode, pressing an OUT-IN combination implements the switch immediately. In the CONFIRM mode, the TAKE button must be pressed to authorize the switch. In the AT ONCE mode, you save time as execution is immediate and actions require no user confirmation. However, no protection is offered against changing an action in error.
7.3.2 Confirming a Switching Action To confirm a switching action (in CONFIRM mode), do the following: 1. Press an OUT-IN combination. The corresponding input number that is displayed in the INPUT STATUS 7-segment display flashes. The TAKE button also flashes. 2. Press the flashing TAKE button to confirm the action. The corresponding input number that is displayed in the INPUT STATUS 7-segment display no longer flashes. The TAKE button illuminates.
2. Press one of the INPUT SELECTOR buttons from 1 to 15 (this becomes the setup # in which the current status is stored). If in the CONFIRM mode, press the flashing TAKE button to confirm the action. The memory stores the data at that reference. 7.4.2 Recalling an Input/Output Configuration To recall an input/output configuration, do the following: 1. Press the RCL button. The RCL button flashes. 2. Press the appropriate INPUT SELECTOR button (the INPUT SELECTOR button # corresponding to the setup #).
7.5 Adjusting the Audio Gain Control You can adjust the gain control for each input and output signal using the latest K-Router Windows®-based control software (provided). See the Hex Tables for Audio Input/Output Gain Control in Section 11. 7.6 Locking and Unlocking the Front Panel To prevent changing the settings accidentally or tampering with the unit via the front panel buttons, lock your VP-1608. Unlocking releases the protection mechanism.
7.7.1 Resetting to the Current Status You can reset the VP-1608 unit to the current status (reloads the current setup) To reset a VP-1608 unit to the current status, do the following: • Press INPUT buttons 1 and 5 simultaneously for 3 seconds The VP-1608 unit resets to the current status, momentarily displaying the unit characteristics, as described in Section 7.8. In addition, the unit characteristics also appear immediately (and automatically) after switching on the power 7.7.
8 Flash Memory Upgrade The VP-1608 firmware is located in FLASH memory, which lets you upgrade to the latest Kramer firmware version in minutes! The process involves: 8.1 • Downloading from the Internet (see Section 8.1) • Connecting the PC to the RS-232 port (see Section 8.2) • Upgrading the firmware (see Section 8.3) Downloading from the Internet To download the up-to-date file from the Internet: 1.
