Hi Res ECL Buffer DIP Switch Settings

Verify that the Hi Res ECL Buffer internal DIP Switch settings are correct for
your system application. To open the plastic housing, insert the flat blade of a
screw-driver, or similar object, into the slot recess at either end of the enclosure
and gently pry the halves apart. Once opened, orient the assembly so that the
internal DIP switches match the orientation in the diagram below. Use the
diagram and the table beneath it to verify or change the settings as required. An
incorrect setting will not cause damage to the Hi Res ECL Buffer or the system
being interfaced. Once settings are complete, snap the halves of the enclosure
together.

Hi Res ECL Buffer Operation and Installation Hi Res ECL Buffer Operation and Installation

Hi Res ECL Buffer Operation

The Extron Hi Res ECL Buffer is for use when interfacing high resolution ECL
signals from graphic workstations or PC's to a compatible graphics projector or
monitor. The buffer is used in combination with any one of the RGB interfaces
listed below to provide a buffered signal to the interface while maintaining its
resolution and bandwidth.

The Hi Res ECL Buffer must be used in combination with a Monitor Breakout
Cable (MBC) corresponding to the ECL signal from the original source PC or
workstation. For example, when interfacing a Sun Monochrome Workstation, use
the Hi Res Buffer along with an MBC Sun/Apollo cable (P/N 26-198-01).

Power is supplied to the Hi Res ECL Buffer, through the cable, from an MBC
power jack located on the RGB Interface device.

The following Extron interfaces are compatible with the Hi Res ECL Buffer:
RGB 106E RGB 108 RGB 108 PLUS

RGB 116 RGB 118 RGB 118 PLUS
RGB 120 RGB 200 RGB 202
RGB 202 PLUS RGB 202xi RGB 202 VS2
RGB 202 VS SL2 RGB 202 VTG RGB 300

Installation Instructions

Prior to installing the Hi Res ECL Buffer, verify its internal DIP switch settings
using the procedure on the back page.

Required equipment for installation is:

• Hi Res ECL Buffer (P/N 26-177-01)

• RGB Interface (See list of compatible interfaces on facing page)

• MBC cable compatible with computer being interfaced

1. Turn system power OFF. (Use diagram on facing page with instructions below.)

2. Disconnect the local workstation monitor at the system.

3. Connect the MBC cable labeled COMPUTER (3A) to the computer system's
video output port. Connect the cable connector labeled MONITOR (3B) to the
system's local workstation monitor (3C). If the MBC cable is the type with a
molded dual connector at one end (as pictured below), connect the system cable
to one side and the monitor cable to the other side of the dual connector.

4. Connect the MBC cable 9 pin female connector labeled INTERFACE to the Hi
Res ECL Buffer input connector located on the front panel (4).

5. Connect the Hi Res ECL Buffer cable 9 pin female connector to the Analog/ECL
input of the interface being used (5).

6. Plug the Hi Res ECL Buffer power connector (6) into the Interface MBC power
jack which is located on the rear panel of the Interface (front panel of RGB 118
and RGB 118 PLUS).

NOTE: To activate power to the Hi Res ECL Buffer, an RGB 106E, 108, 200 or 202

must have dip switches 1 & 8 in the ON position. An RGB 108 PLUS or 202
PLUS must have dip switch 3 in the ON position.

7. Turn power ON and check for proper operation.

8. A Blue Enhance adjustment is available on the
bottom of the Hi Res ECL Buffer enclosure
(See picture to the right). This adjustment
allows tweaking a blue text display to an easier
to read blue-green color.
