A loopback test involves setting up the EDR to communicate from its own master to slave port. This tests that both ports are functional.

==Test Instructions==

* Disconnect any wires in the EDR pins 3-8 and set aside. (We recommend taping over the wires so they don't short to anything)
* With two spare short wires, connect 4-7 and 5-8

* Connect to the EDR wifi ([[EDR_Wi-Fi_Console#Connecting|See here for instructions]])
* On the "Modbus Master" tab, pick any row that has a register set to something other than "0", and set the ID to "10"
* Within one minute, the value should go to some number and the age should reset to 0s and start counting up (TEST PASS)
** If the test passes, the module comm hardware is verified ok

===If test fails===

If the test fails, check a couple other settings:

* Under Modbus Master - Network Configuration, verify this config: Baud 9600, data size 8 bit, parity none, stop bits 1, and "use serial" box is checked
* Under Modbus Slave - Network Configuration, the slave ID should be 10
* Under Modbus Slave - Network Configuration, verify this config: Baud 9600, data size 8 bit, parity none, stop bits 1

If the above is verified and the test still fails, the module ports are likely bad.

==After the test==

*Return wires to original locations
*Set the modbus master row where the ID was changed to "10" back to the original ID (usually "1")
