1W340C series

Embedded LAN interface,8 channels temperature system(W340C_H2)

Embedded LAN interface,8 channels temperature system(W340C_H2)


1. Features

(1) This device supports three types probes ( Tx sensor , Dx sensor and Hx Sensor ). But, both cannot be used at the same time.

(2) Equipment can connect up to 8 probes.

(3). Software support Windows series, and support real-time temperature display, log records, curve shows, MSN remote view data, E-mail alarm etc. Function

(4). Equipment support UDP, in which the TCP protocol, either as a server but also as a client. Server maximum can support five units (client) at the same time. UDP only support the client

(5). Equipment LAN module can be configured

(6). Equipment support reset function, when IP changes or forget the IP, you can long press "Preset keys” 3 s can be restored to the default value.

New Functions !!

3. Operating Instructions



3.1 . Operation steps


3.1.1   First put sensors inserted to 1W340C green interface, connect network Cable .please ensure that connect normal.

3.1.2  Turn on the power .LAN port of LINK light blink, flashing that said ACK network connection to normal. If not, please check your network is normal or not. Red LED the unusual light flashing, said equipment find probe, and reading temperature. If not, please check your probes whether good connection, you can connect well probe again after restart your device.

3.1.3  Open software, if your IP section is not our default 192.168.1. XXX section, please manually add own IP section, (see picture 3-2-1 and 3-2-2)

3.14   Add IP successful, and then open the software can find equipment if still can't find your IP that prove setting wrong or subnet mask setting wrong. When you find device, then you can modify the device's IP.

3.15   At this time, the normal work equipment, if temperature display “error” , that says the probe didn't insert or contact undesirable, please adjust the probe .


3.2 Frequently Questions and resolution
1 Q: why
Equipment connected not succeeds ?
 A: Checking
Network Cable connected and Checking your LAN IP segment. If continue does not work, Please press the reset button, IP restore the factory settings.
2 Q: why the device cannot find the probe?
A: whether it is operational problem?  Please ensure that all equipment with a good, then, connect the power, the device will immediately search the probe.  So, please check whether the probe is connected short circuit or poor contact. Because this is a line of communication, if there is a probe connect poor, all the other probes would happen error.
3 Q:
Why read the temperature will be 85 or ERROR ?.
A: This usually is because the probe cable is too long or the probe too much, resulting in the probe power supply shortage. Solution 1: Use low impedance of the cable and the line length should not exceed 10 meters, or probe plus extra power (+5 V). Solution 2: Ensure the interfaces reliable contact.
4 Q: Why does the device will be dead running some days later?
A: 1. this equipment should not be on the high temperature and high pressure areas. 2. Part of Probe connection has short circuit problem.

3.2   Manually add IP section

if your IP section is not our default 192.168.1. XXX section, please manually add own IP section, (see picture 3-2-1 and 3-2-2)
