16. Simultaneous Data over GPRS and SMS

When GPRS data upload is unsuccessful, GSX8 will redial and try to connect to GPRS network for re‐

uploading the data.

During the redial interval or re‐uploading the data via GPRS DATA, any SMS command will be lost and

schedule SMS data upload will also be dismissed.

Therefore, when the GPRS data upload interval is short, it is recommended to select a longer SMS

upload interval and vice versa.

It normally takes about 45~60 seconds to complete an incoming SMS command or outgoing SMS data

upload.

17. Data over Ethernet

17.1) Ethernet Data

Both UDP & TCP protocol are supported in Ethernet Data.

Packet Data format over Ethernet is supported only when GPRS is enabled.

17.2) Data Upload Interval

Upload Interval is the same for both GPRS and Ethernet Data.

17.3) Can the server receiving GPRS data and the server receiving Ethernet data the same computer?

Computer installed with Ultimate Server software will be able to receive data over GPRS

and Ethernet at the same time.

Only one record can be retrieved each time via SMS owing to the limitation of SMS text length.

Storage Period:

1) Internal Memory: 1MB

2) Records can be kept in the device at about 90 days when logging interval is at 15 minutes.

3) The storage period can be longer than 90 days when logging interval is set at 60 min.

4) When there is no record data on selected date, packet data will only include characters “9”.

20. How Data Logger response on alarm?

Alarm is triggered when Digital Input state is changed or AD Input reading is higher or lower than user

preset values. User can be alerted via Ethernet, SMS or GPRS when alarm is triggered.

When first level alarm is triggered:

Live Data will be uploaded to Server via GPRS or Ethernet header: STH

Live Data will be sent to Control Centre via SMS header: STH

Alarm Text will be sent to Alarm Phone via SMS header: STA

When second level alarm is triggered:

Live Data will be uploaded to Server via GPRS or Ethernet header: STG

Live Data will be sent to Control Centre via SMS header: STG

Alarm Text will be sent to Alarm Phone via SMS header: STA

Example:

When Temperature 1 is over alert high value “85.00”, message “It is hot” is sent to user.

Alarm Phone receives alarm text message:

STA:000000:TM:2009/12/08/16:10;A13:85.00,It is hot

Centre receives data message:

#STH:000000,000;L:310;TM:03/04/2009,09:34;D:1;T:01;C:25;A00:0.166;A01:00000;A02:0.578;A0

000;A12:00000;A13:31.00;A14:30.93;P01:00000000;P02:00000000;P03:00000000;P04:00000000

;P05:00000000;P06:00000000;K01:13333330000000000;O01:0000;8F#


~ 36 ~

21. Temperature Alarm Delay Time

Alarm is triggered when TEMP 1 ~ 8 temperature reading is higher or lower than user preset

values.

Alarm will only be valid when the temperature keeps at higher or lower level for the time delay.

User will only be alerted via SMS, GPRS or Ethernet only after the preset delay.

When temperature reading returns to normal level within the time delay, the alarm will be

cancelled.

Configure the Temperature Alarm Delay Time:

Command: 888888#TDY:xxxx#

Y: Temperature Channel (TEMP 1 ~ 8)

xxxx Delay Time (0000 ~ 9999 seconds)

Note: When the freezer or cold storage door is open for a while, the temperature may rise to an

alert level during the worker operation. It is useful to avoid this kind of false alarm.


~ 37 ~

22. Capturing, Logging & Upload

1. Data Capturing

It captures data from sensors every 2 seconds checking the alarm levels.

2. Data Logging

It logs the captured data into its internal memory in interval of 5/15/30/60 minutes options.

Logging interval is user programmable.

Every logging interval, one record of data will be stored in internal memory.

3. Data Upload

It uploads the logged data records in interval from 5 second up to once a day.

Upload interval is user programmable.

4. Packet Data

When “Packet Data” is selected, more than one data records will be uploaded in packet.

For example:

Logging Interval = 5 minutes Upload Interval = 15 minutes

At 8:00 am, GSX8 will upload three data records logged at 7:50, 7:55, and 8:00 am in one packet.

At 8:15 am, GSX8 will upload three data records logged at 8:05, 8:10, and 8:15 am in one packet.

5. Live Data

When “Live Data” is selected, only the last and real time data record will be uploaded.

For example:

Logging Interval = 5 minutes Upload Interval = 15 minutes

At 8:00 am, GSX8 will upload one data record captured at 8:00 am.

At 8:15 am, GSX8 will upload one data record captured at 8:15 am.

Data records at 8:00, 8:05, 8:10 and 8:15 am will be logged (saved) in internal memory. But only

data captured at 8:00 and 8:15 am will be uploaded.

6. Instant Data Upload

When GSX8 receives 999999#STATUS# command, it will capture the instant data and upload it.

That means it will upload the real time data upon this command.

However, this data record will not be logged (saved) in internal memory.


~ 38 ~

23. Testing Data Upload

A) Testing GPRS Data Upload

Free bundled testing software “GSX8_Centre” is used to test the GPRS connection, data upload and

device operation. Both UDP and TCP are supported.

Please check carefully your local network and router configuration. In the example case:

GPRS Data Logger – server network configuration

GPRS Server IP: 210.3.133.88

Server Port: 9050

Computer running the GSX8_Centre should have the following network properties.

Computer IP: 192.168.0.12

Local Port: 9050

Router Setup

When router is installed between the PC and Internet, please open the ports for UDP and TCP.

Firewall Setup

Click “GSX8_Centre” program as exception in Firewall or disable the firewall.

Open the ports defined by GSX8_Centre in the firewall setting.


~ 39 ~

B) Testing Ethernet Data Upload

Free bundled testing software “GSX8_Centre [UDP]” is used to test the GPRS connection, data

upload and device operation. Only UDP is supported via Ethernet.

Please check carefully your local network and router configuration. In the example case:

Ethernet Data Logger – its own network configuration

Device IP: 192.168.0.200

Device Port: 7005

Ethernet Data Logger – server network configuration

Server IP: 192.168.0.18

Server Port: 6005

Computer running the GSX8_Centre should have the following network properties.

GSX8 Centre IP: 192.168.0.18

Local Port: 6005

Please refer to “GSX8_Centre” manual for detail.


~ 40 ~

24. TCP and UDP Operation

(1) Data Format: TCP

This is a type of handshake data transmission with auto data recovery to ensure accuracy. When

the network signal coverage is weak, data transmission bandwidth will be huge.

(2) Data Format: UDP

This is a type of data upload without checking the data accuracy. Data transmission bandwidth

can be expected or preset in advance.

In UPD format, packet data is considered as a secure way of data transmission to ensure the

receipt of data in control centre.

GSX8 sends out the data packet to control centre (CTR IP). CTR IP replies with “@888” message

once it receives the data. GSX8 will try to resend the data packet if reply message “@888” is not

received.

(3) Data Acknowledge

When Server receives the data from GSX8, it will be acknowledged with the GSX8 current port

number and IP address. A confirmation message “@888” will be replied to GSX8. If any control is

necessary, CTR IP can send the command as “@888xxxxxxx” (e.g. @888888888#SDx:y#) to GSX8

at the same time. Usually, this method of sending command is secure because the port number

and IP address of GSX8 will remain unchanged within 60 seconds after GSX8 sends out data. It is

normal that the port number and IP address of GSX8 will only be released when GPRS Internet

connection is idle after 60 seconds.
