FloBoss 407 Instruction Manual
2-8 Rev 5/00
The communications connectors on the processor board provide the FloBoss 407 with electrical access
and mounting provisions for the optional communications boards. The communication board mounts
directly on the connectors on the processor board and is held in place with a screw passing through the
communications board to a standoff on the processor board. The communications boards available for
the FloBoss 407 allow the options of serial data communication, modem, radio modem, or leased-line
modem communications.
A 3.6 volt lithium battery provides backup power for the RAM and the real-time clock. The backup
battery mounts on the processor board with a spring clip to hold it in place. The processor board has
provisions for mounting a second backup battery. This provision allows the user to replace the battery
without losing backup power to the FloBoss 407.
The real-time clock provides the FloBoss 407 with the time of day date, month, year, and day of the
week. The time chip automatically switches to battery power when the board loses primary input
power.
An LED indicator on the processor board shows the system status. The system status indicator, when
on, indicates the unit is normal; when blinking, indicates the processor board is not running; and when
off, it means a missing or out-of-tolerance input voltage.
The RESET switch permits a special type of cold start from the factory default configuration (contained
in the boot block of flash memory) rather than from the configuration saved to permanent memory (as
in a normal Cold start). Hold the RESET switch down during power-up to initiate this cold hard start;
otherwise, the switch has no effect. Perform the RAM backup procedure before performing a Cold
start. Refer to Section 2.5.2, Backup Procedure Before Removing Power on page 2-21.
2.2.3 FloBoss 407 Termi nation Board Description
Refer to Figure 2-1. The termination board provides the following functionality to the FloBoss 407:
♦
11 to 30 volts dc input power supply
♦
Board temperature and voltage monitor inputs
♦
Built-in field input terminals
♦
Expansion I/O module terminals
♦
External modem port
♦
Communications board port
♦
MVS port
♦
Operator interface serial port
The FloBoss 407 operates with an 11 to 30 volt dc power input to the termination board. A power
indicator LED lights when an input voltage with the proper polarity and level is applied to the power
terminal block if the power input fusing/protection is operational.
