Frame Bus Jumpering
If you will be using this 8977AP module to distribute reference Frame Bus 1
(slot 1) or Frame Bus 2 (slot 3), you must set a jumper (GEN XMIT shown
in
Figure 4 ) on the front module circuit board for this purpose before
installing the module.
• Frame Bus 1 – to transmit the reference connected to the Reference In
BNC on the corresponding rear module on Frame Bus 1, set jumper J2
to
ENA (pins 1-2). This module must be installed in slot 1 of the frame
and configured on the Genlock web page (see the Genlock Web Page on
page 49 ) for Auto in the Drive Frame Reference Bus pulldown.
• Frame Bus 2 – to transmit the reference connected to the Reference In
BNC on the corresponding rear module on Frame Bus 2, set jumper J3
to
ENA (pins 1-2). This module must be installed in slot 3 of the frame
and configured on the Genlock web page (see the Genlock Web Page on
page 49 ) for Auto in the Drive Frame Reference Bus pulldown.
Note Both jumpers may be enabled. The module in slot 1 will only read the status
of jumper, J2. The module in slot 3 will only read the status of jumper, J3.
