28 209351 REV B Operations Manual, Redundant System Controllers
SysAddr sets the controller unique network address. The address range is 1 to 255.
As with any RS-485 network the RCP address must be unique within every serial
network. The controller will answer on serial commands only if its address matches the
address sent in the serial packet.
Logic refers to the fault state logic for the External Alarm Input port, J8. The factory
default setting is a logic high state for external alarm fault status. This is consistent with
(contact open = fault ) logic used in most systems. However if used in a system that
employ reverse logic, this setting can be used to adjust the RCP controller accordingly.
Latch refers to the fault latching function. The possible states are “Enb” and “Dis” for
fault latching enabled and fault latching disabled. The factory default state is for fault
latching to be enabled. This means that after a fault has been detected, the RCP
controller will continue to indicate an alarm even after the external fault may have been
removed. To clear a latched fault the user must press the “Enter” button when the
controller is in the Sys Info page.
3.3.1.3 Sys Info - Page 3
This page pertains to the internal monitor and control settings of the RCP controller.
Track refers to the system fault tracking method. Available selections include LNA, EXT
(External), and Both. This option specifies which elements are to be included into the
redundant system. The user can select fault tracking based only on internal current
monitoring such as in LNA / LNB systems, by external inputs from External Alarm port,
J8, or both.
Prior is the Priority control of the system. This option is only used in 1:2 redundant
systems in which priority must be assigned to polarity 1 or polarity 2 of a given antenna
system. This is only used if both on line amplifiers fail in a 1:2 redundant system. The
priority setting determines the polarity, or switch position, the system should assign to
the standby amplifier.
Ctrl specifies Local or Remote mode of controller operation. This function can also be
accessed by the dedicated Local/Remote key on the front panel. When in Remote mode,
all other front panel keys are disabled with exception of the Local/Remote key.
Mode indicates and selects the Automatic or Manual mode of the controller. This
function can be accessed by the dedicated Auto/Manual key on the front panel.
Window allows the user to select the current window setting for fault detection in an
LNA / LNB redundant system. The possible selections are: 8%, 12%, 15%, and 20% of
the nominal operating DC bias current. The factory default setting is 12%.
Buzzer allows the user to enable or disable the internal audible alarm. The factory
default setting is enabled.
