1-Wire Humidity node

1-Wire Analog voltage node

Ideally suited for temperature (humidity) monitoring in computer servers rooms, laboratories, technologies.

Now Humidity 1-WIRE Sensor available.

1-Wire Analog voltage inputs for monitoring values from industrial sensors with voltage/current outputs.

10 Base T Ethernet / RJ-8 connectivity.

Solution for Wireless WIFI 802.11 remote monitoring.

TCP/IP protocol with standard TELNET software's supporting for IP address configuration, temperature inspecting, name sensors editor, LO/HI borders

most popular ICMP for ping available.

Implemented SNMP 1.00 protocol
Running under more platforms as UNIX, LINUX, WIN
Ready for HP OpenView

Suited for MRTG UNIX SNMP Management

See Another SNMP management RRD tools

Also MIB file included.

SNMP Adapter sending messages: UDP Traps if temperature on each sensor reach LO/HI temperature.

16 sensors DALLAS MICROWIRE DS1822 (DS18S20) supported

Max length between two sensors - 15m

Simple wiring between sensors / only 1 cable line 4-wire is needed

RS232 connectivity for MAC address editing, sensors configuring.

Implemented 120 MIPS Risk Processor UBICOM IP2022.

Ethernet		Telnet
SNMP adapter is equipped with Ethernet 10MBit 10-Base T, through RJ-45 (8P8C) standard connector mounted on front panel. Adapters are connected to any Ethernet HUB, Switch. For 100 MBit Nets it is needed to use 100/10 AutoSwitch. Implemented protocols: ARP, ICMP, TCP/IP TELNET, UDP SNMP, IP address, IP mask, Default Gateway: configurable by the TELNET, or RS232 standard terminal programs. Routing: static by default gateway. IP Default GateWay is used to interconnection between nets. GateWay IP setup user can edit by TELNET or by RS232 commands MAC address: configurable by RS232 terminal (Hyperterminal, Winterm, term90, ...		In adapter is implemented standard TCP/IP Telnet application. By Telnet, user can inspect all actual temperatures. User can access device settings by password: adapter name sensors names LO/HI temperature borders for every sensor, TRAPS period adapter IP address, Mask, Gateway see Telnet commands
SNMP protocol		RS-232 connectivity
Standard connectivity to temperatures is SNMP Ver:1.00 protocol. SNMP (Simple Network Management Protocol) is layer under UDP port 161. For more informations follow http://www.snmplink.org/ SNMP guarantee connectivity under more platforms UNIX, LINUX, WIN ... More monitoring programs is dedicated for SNMP: UNIX HP OpenView Windows MIB Browser - manufacturer - MG soft FREE Windows SNMP browser: http://www.netzwerkseite.de MRTG very nice Free GNU Project with PERL scripting, generating HTML Graphical outputs ...		On device back panel is standard RS232 connector DSUB-9 mounted. Standard ASCII terminal is implemented with menu navigation on baud rate 9600,N,8,1. User can communicate with standard terminal from any host, PC with MS Windows, DOS, Palm OS ... RS 232 Menu description you can visit here
Implemented MIBs		Temperature sensor
Under SNMP layer In adapter is implemented MIBs. (Management Information Base) Download MIB file here: MTECH-DSTEMP-MIB.mib MIB File is needed for softwares HP OpenView, MGSOFT MIB Browser. Click here to visit agent MIB structure.		As temperature sensor are strictly used DALLAS Semiconductor digital sensors DS1822 or DS18S20. All sensors are connected to adapter in common 3-wire bus. Specifications: Range: -40 .. 125'C Resolution: 0.1C Maximum error: +/- 0.5C Number of sensors: up to 16 Temperature sensor is delivered with RJ 4-4 HUB. it is the simple way to make connections between sensors and SNMP adapter. Used is 4-wire standard phone line cable crimped with RJ4-4 connectors. 2wires is used for Ground.
