Server monitoring system is designed for 19-inch rack mounting, the height is one rack unit - 1U. 

Model H4531R is prepared for connection of external Pt1000 temperature probe and models H3531R, H7534R are equipped with 1 meter temperature + humidity probe. Unit also contains three binary inputs for detection of two-state events - e.g. power presence, water, smoke, airflow, glass break detection, door contact 

Rack unit provides 5Vdc and 12dc power supply for external all sensors and detectors. 

Large dual line LCD for simultaneous display of temperature, humidity is an advantage. Parameters are easy adjustable from transmitter keyboard or from the computer. 

State-of-the-art capacitive polymer sensor ensures excellent calibration long term stability, inertia against water and condensation 
 
Environmental monitor is equipped with two relay outputs for alarm indication or control of external devices. Each relay can be assigned to any measured value. 

Modes of Communication between Transmitter and Computer

• Modbus TCP: Modbus TCP protocol enables to read measured values, set alarm limits, adjust the probe. 
• Telnet: Port 9999 enables to set alarm limits (lower, upper limits, hysteresis for measured values and time delay), e-mail addresses, SNMP addresses, probe description, refresh of www pages (10s to 65535s), set storing interval to history (10s to 65535s), enable each communication channel. Capacity of the history memory is 100 sets of temperature, humidity, pressure + computed values. Password protection of this port is enabled. Automatic IP address assignment from DHCP server is also enabled. 
• WWW Pages: User selectable design of www pages enabling to display curve of measurement history. User can design the look of www pages and temperature, humidity, pressure + computed values history. 
• SNMP: It is possible to read actual values and alarm limits. In case of alarm creation warning message (trap) is sent to addresses defined by the user (maximum three addresses). 
• SOAP: Online transmitter enables to send actual measured data in the format of SOAP message to selected web server in preset interval 10-65535 s. In case message is not received by the server till next message is sent, warning trap 1/2 is sent. 

Transmitter Alarm Indications 

• E-Mail: In case of alarm creation warning e-mail message is sent to addresses defined by the user (maximum three addresses) or via e-mail to SMS message. 
• SNMP: In case of exceeding of adjusted temperature, humidity, pressure + computed value limits alarm is activated and warning trap is sent to user specified IP addresses (maximum 3 addresses). 
• WWW Pages:  In case of exceeding of adjusted temperature, humidity, pressure + computed value limits active alarm is displayed on www page. 
• Syslog: Online transmitter enables to send text messages to selected syslog server after different events appear. E.g. after transmitter restart, alarm activation, communication error with SNTP, write to transmitter via mdb, sntp, after firmware change, after alarm termination, after communication error with SOAP server.
