Connecting the VTG Output Cables

VTG 200

The VTG 200 (above) provides six sets of video output connectors; the VTG 150 (at right) provides four sets. Each connector is marked for its video application.

See the table of video scan formats on page 4-1 and choose the one to be used to simulate your computer. Then connect the appropriate cables to the device to be tested. (e.g. projector, switcher, etc.)

15-Pin HD (VGA/XGA) Output

One connector is provided for the VGA/ XGA because the pin configurations are identical. All scan rate signals go to the VGA/XGA (15-pin HD), Apple/MacII/Quadra (15-pin) and BNC connectors. The BNC output is individually buffered, allowing devices to be connected to BNC and VGA/XGA outputs at the same time. However, because the VGA/XGA and Apple/ MacII/Quadra outputs are in parallel, they should not be connected at the same time.

_ If devices are connected to both 15-pin outputs VGA/XGA &

Apple/MacII/Quadra simultaneously, the double termination will result in a loss of brightness.

The pin assignments for the 15-pin HD are as follows:

Pin 1 = Red Pin 8 = Blue Ground Pin 2 = Green Pin 10 = Ground Pin 3 = Blue Pin 13 = H. Sync Pin 6 = Red Ground Pin 14 = V. Sync Pin 7 = Green Ground

The sync available on pins 13 and 14 is dependent on the position of the H/HV switch. With the switch in the HV (down) position, composite sync is available on pin 13. With the switch in the H (up) position, separate H and V sync is available on pins 13 and 14.

100-240 VAC

15-Pin Apple/Mac II (VTG 150), MacII/Quadra (VTG 200) Output

All scan rate signals go to the VGA/ XGA (15-pin HD), Apple/MacII/ Quadra (15-pin) and BNC connectors. The BNC output is individually buffered, allowing

devices to be connected to BNC and Apple/MacII/Quadra outputs at the same time. However, because the VGA/XGA and Apple/MacII/Quadra outputs are in parallel, they should not be connected at the same time.

_ If devices are connected to both 15-pin outputs (VGA/XGA &

Apple/MacII/Quadra) simultaneously, the double termination will result in a loss of brightness.

The pin assignments for the Apple/MacII/Quadra connector are as follows:

Pin 1 = Red Ground Pin 9 = Blue Pin 2 = Red Pin 11 = C/V Sync Ground Pin 3 = Composite Sync Pin 12 = V. Sync Pin 5 = Green Pin 13 = Blue Ground Pin 6 = Green Ground Pin 14 = H. Ground

Pin 15 = H. Sync

9 Pin, TTL Output

A 9 pin “D” style connector provides all TTL signal outputs. These outputs may be selected from the TTL Scan Rates menu.

Pin 1 = Ground Pin 5 = Blue Pin 2 = Red Intensity Pin 6 = Green Intensity Pin 3 = Red Pin 7 = Blue Intensity Pin 4 = Green Pin 8 = H. Sync

Pin 9 = V. Sync

_ When running TTL rates from outputs other than the 9-pin TTL

output, the test patterns may appear dim, distorted or otherwise unlike the output from the 9 pin connector. This is normal, due to the signal characteristics of TTL video signals. Thus, for exact TTL signal duplication, only use the 9 pin TTL output.

RGB Output (BNC, Analog)

Connecting the VTG Output Cables

The RGB BNC output provides red, green, and blue video at 0.7 volts peak to peak and horizontal and vertical sync at TTL levels on the H/HV and V BNC connectors. Those five BNC connectors, together with the 2-position switch, can be used four ways:

• RGB with composite horizontal and vertical sync (4-cables)

• RGB with separate horizontal and vertical sync (5-cables)

• RGB with Sync on Green (3-cables)

• RGB with sync on red, green, and blue (3-cables)

Composite vs. Separate H & V

The vertical sync is provided on the BNC connector marked V. Depending on the position of the toggle switch, the H/HV connector can have either a separate horizontal sync, or a composite horizontal/vertical sync. For example: for composite sync output, put the toggle switch in the HV position and don't use the V connector. For separate H & V sync output, put the switch in the H position and connect cables to both the H/HV and the V connectors.

Sync on Red, Blue, or Green

Sync on Green may be removed or added for all scan formats. If normal operation of the selected scan rate is Sync On Green, that is what the VTG will output. However, the sync may be removed by following the instructions in Chapter

13W3 Sun/SGI/IBM Output (VTG 200 only)

The pin assignments for the 13W3 connector are:

Pin A1 = Red Pin A2 = Green Pin A3 = Blue

Sync pin assignments vary by manufacturer as follows:

Signal Sun SGI IBM NXT

H/HV 5 3 5 A2 (SOG) VNC49NC Ground 10 10 10 10

Adapting the VTG 150 to Other Standards

For some applications, the unit to be tested may not have connectors that match those provided on the VTG 150. Adaptor cables can be made up to serve this need. Following are some examples.

The sync polarity (positive or negative) of the BNC H & V output is identical to that of the selected computer.

To output negative composite sync at all times (optimum for converging video projectors), place the back panel toggle switch in the HV position. All frequencies may be output on the BNC connectors.

NTSC/PAL BNC Output (VTG 200 only)

The VTG 200 NTSC/PAL BNC connector provides composite video output when an NTSC or PAL scan rate is selected.
