If the Door station Mic using DS01 or DS02 cannot be heard on the keypad, but the keypad mic can be heard on the door station, please check the shunt J6 on the DM02 The shunt should be inserted on J6. The location of J6 is shown below Note that older versions of the DM02 do not have the J6 shunt. J6 is unshunted for certain models of 3rd party door station but most need to have J6 shunted J6 shunt should be removed for DP03X, inserted for DS01/DS02 J5 Shunt should be connected on DP03X and removed for DS01/DS02 Attachment: dm02-j6.jpg (Downloaded 50 times) Last edited on Wednesday Jan 6th, 2016 03:01 pm by slychiu |

The problem where Door Station microphone cannot be heard on the Keypad but Keypad microphone can be heard on the Door Station can also be due to the Tuning Parameters Tuning Parameter 81 (AFE DP MIC GAIN KP-DP INTERCOM) was normally 3, it should be increased to 6. This increases the volume from DP Mic to Keypad The default templates have also been updated to include this change To Update the default templates, open Comfigurator, go to File Menu >> Update Defaults Last edited on Wednesday Jan 6th, 2016 03:08 pm by slychiu |

Tuning Parameter 81 (AFE DP MIC GAIN KP-DP INTERCOM) is the volume from DP Mic to Keypad. Preferred value = 6 for DS01 Tuning Parameter 79 (AFE KP MIC GAIN KP-DP INTERCOM) is the volume from KP Mic to Door station. Preferred value = 10 for DS01 Increase the appropriate parameter to increase the volume of each direction. However too much increase in volume may cause howling. Settle on a value which results in audible volume in each direction without howling Reset is not necessary after changing and write selective |
