RJ11 Sensor Ports
• Two RJ11 6P4C jacks for daisy-chaining 1-wire temperature/humidity/dew point, thermocouple, or digital input expanders in any combination.
• Up to 24 temperature, thermocouple, or any single reading 1-wire sensor can be split between both RJ11 connectors.
• Up to 8 temperature/humidity/dew point combination 1-wire sensors can be split between both RJ11 connectors. Each temperature/humidity/dew point sensor is equivalent to 3 single reading sensors
• Up to 12 digital input expanders can be split between both RJ11 connectors to allow a maximum of 24 additional digital inputs. Each digital input expander is equivalent to 2 single reading sensors
• Maximum cable length supported on each connector is up to 600ft (183 m) depending on the configuration and number of connected sensors.
• This maximum includes the cable length of each sensor.
• RJ11 splitters or t-tap boards (RJ11-3JCK) for convenient daisy-chaining are sold separately.

Dry Contact Closures
• Two screw terminal pairs for connecting dry contact devices and the liquid detection sensor.

USB Port
• One female Micro USB connector - reserved for future use.

Ethernet Port
• One female RJ45 connector.
• 10/100 Base-T Ethernet interface.

Protocols
• HTTP/HTTPS, SNMP V1/V2c, SMTP, TCP/IP, Syslog, SNTP, DHCP, TLS v1.2, AES 256-bit, 3DES, Blowfish, RSA, EDH-RSA, Arcfour.
• Compatible with any SNMP management software.
• The unit can be polled via SNMP.
• Operates and configures via HTTP/HTTPS web page.
• An IP address can be assigned to the E-MICRO automatically by a DHCP server.
• Generates SNMP traps, email alerts, syslog messages, and SMS messages (via email-to-SMS).
• Alerts are posted in event log, which is accessible through Web user interface.
• Email alerts can be sent to 9 addresses.
• Email alerts are not compatible with TLS.
• Users can configure the schedule for when they will be alerted.

SSLv3
SSLv3 has been disabled in the following browser versions and affects HTTPS connection to the E-1W:
• Microsoft Edge
• Firefox Version 34 and newer
• Opera Version 25 and newer
• Google Chrome Version 40 and newer
• Internet Explorer and Safari: all versions allow SSLv3, if there are connection issues check if SSLv3 is manually disabled.

Physical
• Dimensions (WxDxH): 4 x 3.65 x 1.37 in. (102 x 93 x 35 mm).
• Includes mounting holes to match rack hole spacing.

Power
• Built-in power over Ethernet (PoE) and dual DC power provides triple redundancy.
• Power over Ethernet standards supported: IEEE 802.3af, 802.3at.
• Proprietary schemes such as Cisco Discovery Protocol are not supported.
• Similar legacy switches and routers will have to use PWR-SPLY-ELC.
• If the first power source fails, the unit will automatically, without interruption, switch over to the second power source.
• The unit draws power from the source with the highest DC voltage (nominal 5.5V).
• If two or more sources have exactly the same voltage, it will draw in part from each of them.
• 110 to 240 VAC at 50 or 60 Hz via AC adapter (not included).
• Country-specific AC adapters sold separately (PWR-SPLY-ELC).
• Input voltage: 5.5VDC ±5%

Environmental
• Operating and Storage Temperature: -4 to 167°F (-20 to 75°C).
• Operating and Storage Relative Humidity: 0 to 90% non-condensing RH.
• MTBF: 703,871 hours.
• Regulatory Approvals: CE, RoHS.
