configured,!and!running!properly.!See!Temptime*EDGE*LoRa*Gateway*Receiver*Configuration*
Guide!for!more!details!on!the!receiver!component.!
To%see%whether%an%EDGE%W-200%module%is%within%wireless%range%of%the%receiver:%
1. Press!the!pushbutton!on!the!front!of!the!module!(short!press).!
2. If!the!module!detects!a!receiver,!the!text!“ACK_RECEIVED”!(acknowledgment*received)!is!
displayed!in!the!lower!left-hand!corner!of!the!screen.!Otherwise!“ACK_NOT_RECEIVED”!is!
displayed!(see!Appendix*-*Troubleshooting!on!page!28!of!this!document).!

3.5 Requirements!and!recommendations!
• The!EDGE!Gateway!receiver!runs!continuously,!24/7/365,!and!should!be!connected!to!an!
Uninterruptible!Power!Supply!(UPS)!that!protects!against!power!surges!and!provides!power!to!
back!up!the!receiver.!
• The!EDGEConnect!web!application!will!show!an!alert!clearly!on!the!computer!screen!if!a!module!
is!not!communicating.!You!may!also!verify!connections!by!pressing!the!pushbutton!on!the!EDGE!
W-200!module!and!making!sure!“ACK_RECEIVED”!is!displayed.!
• Recommended!maintenance!and!calibration!procedures!should!be!followed.!
!
3.6 Placing!your!EDGE!module!for!best!wireless!performance!
For!optimal!operation,!follow!these!recommendations!when!physically!placing!your!device:!
• Do!not!place!the!module!within!40!cm!(16!in.)!of!another!module.!
• Make!sure!the!wireless!module!is!not!placed!on!an!electrical!conduit!or!cable!tray!(such!as!for!
computer!network!cables).!
• For!best!results,!place!the!module!so!that!it!faces!the!general!direction!of!the!receiver.!
• Keep!about!20!cm!(8!in.)!of!clear!space!around!the!module.!For!example,!a!module!that!is!
“stuck”!between!two!refrigerators!may!not!communicate!effectively.!
• Make!sure!all!cables,!if!any,!are!firmly!attached!and!that!sensors!are!properly!inserted!in!the!
appropriate!chamber.
