About This Manual
This manual describes the features of a specific module of the 2000 Series
Modular Products family. As part of this module family, it is subject to
Safety and Regulatory Compliance described in the 2000 Series frame and
power supply documentation (see the 2000 Series Frames Instruction
Manual ).

2000A89 Module Adapter Assembly
Introduction
The 2000A89 Module Adapter Assembly consists of a 2000 Series rear
media module and front slot adapter that allows compatible 8900 modules
to be installed in the front slot of a 2000 Series frame (see Compatible 8900
Modules on page 5 ). The 2000A89 module adapts the 8900 mechanical and
electrical connections to the 2000 Series frame. The module has an on-board
±12V power supply to meet 8900 voltage requirements. The 2000A89
assembly includes:
■
A rear mount module with:
■
Two BNCs providing a floating-shield 75
connection,
Eight 75
■
■
±12V power supply that is fused on the input side and short-circuit
protected on the output side.
■
A front frame slot guide assembly to compensate for the width of the
narrower 8900 module.

2000A89 Module Adapter Assembly
Installation
Installation of the 2000A89 module adapter consists of:
Installing the adapter board in the corresponding rear media slot,
■
■
Installing the front slot guide assembly in the desired frame slot, and
■
Installing the 8900 module.
The 8900 modules can be plugged in and removed from the 2000A89 with
power on. Refer to the specific 8900 module manual for power-up, cabling,
and configuration information.
Perform the following to install the 2000A89 Adapter:
1.
Install the 2000A89 Adapter module in the selected rear slot.
The module slides into guides on each side of the frame slot and
secures on the alignment post on the mid-frame motherboard (refer to
Figure 1). Screw locks secure the module in the slot. A Power OK LED
should be visible from the front of the frame when power is applied
(see Power Up on page 7 ).

Install the Slot Adapter in the selected front media slot.
There are twelve media slot locations in the front of the 2000T3 frame
to accommodate either analog or digital modules (Figure 2). The 8900
front slot adapter installed as shown in Figure 3 allows the narrower
8900 module to be installed.
The slot adapter slides along the card guide on the right side of the
frame and onto the alignment post on the mid-frame motherboard. The
front of the assembly is then secured in the track by the locking screw.

2000A89 Module Adapter Assembly
Install the 8900 module in the proper front media slot.
The right edge of the 8900 module slides into the board edge support
track while the left side is inserted between the board edge guides. The
50-pin rear connector should easily align with the rear connector on the
adapter module. Gently press the module ejector tab to seat the
module.

†
Some Grass Valley 8800 and 8500 video DAs with large front panels can
also be installed in the 2000A89 Adapter but require two media module
slots for vertical clearance.
The maximum number of 8900 modules allowed in a frame is determined
by frame cooling capacity. Refer to the 2000 Frames Instruction Manual and
the specific 8900 module manual for power and cooling requirements.
*
Some versions of this module cannot use the bottom media module slots and will require two module slots for component clear-
ance. Contact Grass Valley Customer Support for information..
†
With the 8900FSS option installed, these modules require two media slots for component clearance.

Cabling
The specific function of each 2000A89 BNC connector is determined by the
8900 module that is installed.
Loop-through Input
As in the 8900 frame, connectors J9 and J10 function as a loop-through
input connections (see Figure 5). Terminate the unused connector into 75
if the signal is not looped to other equipment.

Outputs/Inputs
The 2000A89 provides eight BNCs (J1 through J8) for direct (non-looping)
signal connections. The J numbers indicate the same wired connection to
the 8900 module as occurs in the 8900 frame rear connector.

Service
The 2000A89 modules use surface-mount technology to achieve compact
size and adherence to demanding technical specifications. Circuit modules
should not be serviced in the field.
If your module is not operating correctly, proceed as follows:
■
Check frame and module power LEDs.
■
Check for presence and quality of input signals.
Verify that source equipment is operating correctly.
■
■
Check cable connections.
If the 8900 module is not receiving +12 or -12 Volts, check the Adaptor
module’s Fuse F1 (see Figure 7).
If the module is still not operating correctly, replace it with a known good
spare and return the faulty module to a designated Grass Valley repair
depot. Call your Grass Valley Group representative for depot location.
Refer to Contacting Grass Valley Group at the front of this document for the
Grass Valley Customer Support information number.
