Figure 4.3 SIM Card slot DC INPUT Power to REX is supplied from the 12VDC power adapter via the DC jack input. If using user-supplied power supply, observe voltage polarity and voltage level. REX operates on 12VDC input but can accept supply voltage up to 24VDC.
Wiring Instruction: Example (Figure 4.4) shows the IO connection to REX. Power to REX can be from 12-24 VDC via a 4 way Pluggable connector at the below part of REX. A 12VDC adapter is supplied as a standard accessory. The digital inputs are dry contacts type.

REX unit. In order for the PC and REX to connect to each other, the PC must be manually set to a static IP address that is within the same subnet as REX. Given the default IP address 192.168.1.31 and 255.255.255.0 for the subnet mask, a suitable IP addresses for the PC would be 192.168.1.1 or any other IP address other then...

Linkwise Technology Pte Ltd REX User Manual Value This field displays the analog input 4-20mA transmitter reading. Chapter 8: IO Configuration Page This page shows the template for defining input description as well as the status. Each input can assume 2 states, one is when the input contact is closed, and another when the input contact opens.
The status page will show the state of the input, based on the state description configured. TD (Trigger Delay): A unique feature or REX is allowing user to define the valid input change time. This is useful to delay triggering an alarm until the input change is stabilised. For example, door opening. One might not want to trigger an alarm if the door is opened momentarily.
In the example below the Hysteresis is set to 4 then the transmitter would have to drop from 30 to 26 before the status would change from High (Alarm) back to normal. Warning and Error Messages If the user input any values that are out of range, REX will prompt an error. The user must re-enter the correct value.
Forward Number This number (if assigned) will receive alarm SMS like the operation numbers. Any incoming SMS to REX will also be forwarded to this number as well. This is a very useful feature where an organization wishes to have a central logging of all activities (alarms, in-out SMS) of REXs.
REX User Manual Figure 9.4 Forward Number WARNING Never set the forward mobile phone number to be the same as the SIM card number in REX. This will cause the device to send no-ending SMS to itself. SMS Settings Repeat SMS on Alarm State If set, when an alarm is triggered, the SMS will be sent repeatedly according to the number of times specified, to the operation and forward group.
Chapter 10: Relay Output Configuration REX has 2 relay outputs. These outputs can be turn on, off, or pulse remotely via SMS commands. It can also be controlled from locally in or remotely from the web page access (Status page).
Incorrect IP address /subnet mask setting will render REX inaccessible from the network. Invalid IP/Subnet range will also cause REX to be inaccessible from the network. REX do have error trapping and will warn of any invalid settings. If for some reason, the trapping misses and the invalid values are accepted by the unit and cause network connection difficulties, contact your distributor for assistance.
Linkwise Technology Pte Ltd REX User Manual By default, REX’s IP address is 192.168.1.31 and the default subnet mask is 255.255.255.0. This means the IP address of your PC may be set in the range 192.168.1.1 to 192.168.1.254 inclusive but obviously excluding 192.168.1.30, which is the address for REX.
#WOP is to write to the device: Write Operation Phone Note: If a command sent to REX does not match the required format or is invalid, REX will not respond to the querying mobile phone and no action is taken by it. Similarly, if any unauthorized mobile phones try to query a status or to do a set command, it will also not respond to that mobile phone.
