Q/ Why can I not connect the laptop to the Gauge
A/ There are three checks you need to make.
1/ Power down the gauge and power back up, and make sure the bottom right of the display says "Standard" and not "Modbus". If it says Modbus, the protocol needs to be changed whilst you are performing calibrations. To do this, power the unit down, press and hold the "Alarm Test / Acko" Button, and power the unit back up. You have to keep the button pressed for 3 or 4 seconds as the unit powers up to see the "Standard" now appear in the bottom right. Allow at least 15 seconds before powering up or down after changing from standard to Modbus or Vice versa. (This will stop screen pixilation which may occur if the system is diconnected whilst changing between communications languages)
2/ Node ID. This is the address of the gauge for communications. like a house number. You can find this by pressing the scroll screen button. It is likely to be 99 as shipped from the factory, or between 1 and 32 if set by user.
3/ Windows 8 and 10 add port numbers whenever a USB item is connected. You need to know what address the lap-top or PC thinks this is. Please refer to the Document Download above to check the Configuration communication set-up.
More information on this troubleshooting under search "T4020-01"
Q/ The screen has become disrupted / pixilated
A/ A rare occuracnce that is probably caused by power up/down when the unit is changed from Modbus to Standard, or Vice versa, and has not completed its full power up or down sequence. Allow 15 seconds in between changing language protocols.
Q/ How much current does the unit draw?
A/ 80 mA
Q/ How many units can I connect together plus a T-MAC?
A/ You can connect 6 units plus 1 x T-MAC
