The Environmental Monitoring and Control (EMAC) Adapters provide
a compact solution for monitoring the health of a system's internal environment,
including power supplies, temperatures, smoke detectors and cooling fan
operation. Eight open collector and eight digital output lines are also provided
for the control of the monitored system.
The adapter is available in the following industry standard compliant
formfactors :
PMC
Air-coolded PMC adapter with Front Panel I/O (IEEE Std 1386.1-2001)
Conduction-Cooled PMC (CCPMC) adapter with backplane I/O (ANSI/VITA 20-2001)
PC/104-Plus (PC/104-Plus v2.0)
A standalone EMAC unit (based on the board-level EMAC Adapter)
is also available. In the standalone form, the EMAC communicates to its host via
an RS-232 serial link.
Features
The EMAC PMC and CCPMC Adapters employ a PCI-based dual channel, industry standard 16550 compatible UART
The EMAC PC/104-Plus Adapter employs both a PCI and an ISA-based dual channel UART. Either of these can be configured to interface with the EMAC functions, the other UART providing two additional COM ports to the user
Equipped with a Watchdog Timer to restart the EMAC PMC Adapter in case of software failure
The firmware is field upgradeable
Functions
Monitoring
Power Supply Voltages
Up to six positive and two negative DC (Direct Current) voltages can be
monitored via a 10-bit analogue-to-digital converter. The EMAC PMC Adapter is
configured to monitor -12 V, +5 V, +12 V and +24 V by default, but can be
modified to measure a wider range of DC voltages.
Temperature
Up to eight DS18S20 or DS18B20 temperature sensors can be monitored at any time.
Power to the sensors is supplied by the EMAC PMC Adapter.
Fan Speed
The rotation speed of up to eight cooling fans can be monitored at any time. The
EMAC PMC Adapter is able to connect to an open collector signal output or a TTL
compatible output of a cooling fan sensor equipped with Pulse Width Modulated (PWM)
outputs. The output signal of each cooling fan is isolated by a photocoupler.
Smoke Detectors
The status of up to eight smoke detectors can be monitored at any time by the
EMAC PMC Adapter. The output signal of each smoke detector is isolated by a
photocoupler.
Controlling
Eight outputs to drive, for example, LEDs. Eight open collector
outputs can sink 24 V @ 1,6 A each to control, for example warning lamps and
alarms or for other functions. The default configurations are :
Power Warning : When any one of the power modules exceeds the
user-specified operating temperature.
Temperature Warning : When any one of the temperature sensors indicates
temperatures outside the user-specified range.
Voltage Warning : When any one of the power modules operates outside the
user-specified voltage limits.
User Warning : Any function can be implemented in firmware on request.
