A super capacitor ("super-cap") and a coin type battery work together
to provide backup power for the static RAM and the real-time clock.
This helps to ensure retention of short and longer-term data,
configuration, and operational integrity when the FB107 is not in
service or is in storage.
For information on replacing the battery, refer to Section 2.5.1,
Removing and Installing the Battery.
Note: The super-cap is not field-replaceable.
The built-in inputs and outputs (I/O) on the CPU consist of a 3- or 4-
wire 100-ohm resistance thermal detector (RTD) input interface and five
diagnostic analog inputs (AI) that monitor the:
Logical voltage.
Battery voltage from the backplane voltage input connector.
Charge in voltage originating from the CPU power input.
System milliamps originating from the power input from the CPU.
Board temperature originating at the CPU.
The FB107 supports up to four communication ports. The base CPU has
three built-in communication ports:
Local Operator Interface (RS-232C) – LOI for asynchronous serial
communication (Local Port).
EIA-485 (RS-485) – COM1 for asynchronous serial communication.
EIA-232 (RS-232) – COM2 for serial communication.
The Local Operator Interface (LOI) port provides for a direct, local
link between the FB107 and a personal computer (PC) through an
optional Local Operator Interface Cable using EIA-232 (RS-232C)
communications.
The LOI local port allows you to access the FB107 for configuration
and transfer of stored data. The LOI port is capable of initiating a
message in support of Spontaneous-Report-by-Exception (SRBX)
alarming.
The LOI is software-configurable with baud rates from 300 to 115.2 K
and it uses a DB9 connection.
You can purchase an LOI cable from your sales representative.
