Hello, We have a few of these kits that all have different signals. There is 5 of them we are using to transmit alarms from various places in our plant and they transmit to a single alarm panel that houses the 5 receivers. This set up was working great. we wanted to duplicate two of the alarms in another location so we bout two more MirCR2x_kits but ordered each one with an extra receiver. I swapped them out in the panel but it seems like one of the new kits is interfering with one of the older MirCR2x_kits that was not changed out. The Transmitter unit when the contacts close the transmitter is supposed to send the signal to the receiver the relay lights on the transmitter start flashing on and off instead of being steady. The correct alarm and light on the receiver also starts turning off and on instead of being steady, but one of the other alarm lights also starts to go off in synchronous with the correct one, like it is being actuated from the wrong transmitter. It makes me think they are cross communicating. I was curious your thoughts on the issue.
Hi John,
Its possible for cross talk when a pair of mirror boards are ordered with an additional receiver. When ordered with an additional receiver the mirror boards utilize a broadcast message that goes out to all nearby devices. Generally when ordered in this way our production staff will use a different network ID so that each set will not cross talk to another set.
However if these sets are installed into locations with other Mirror devices already its possible that the network IDs will be the same.
The only resolution would either be an RMA (Log In ‹ NCD.io — WordPress) and we can reconfigure the devices here or you can order a USB Configuration Adapter (https://store.ncd.io/product/usb-configuration-adapter-for-ncd-communication-modules/) which would allow you to reconfigure the kits on location using a windows computer and XCTU (Digi XCTU — Download and Install the Configuration Platform for XBee/RF Solutions | Digi International).
To reconfigure on your end you would follow these steps:
- Power down the Mirror board
- Remove the wireless module (Small offboard module with antenna/antenna connector
- Put the wireless module in the USB Configuration adapter
- Connect adapter to computer via USB
- Run XCTU
- Connect XCTU to the USB Serial Port
- Change the network ID to something unique to your site (i.e. 7000)
- Write the changes
- Remove the wireless module from the USB Configuration adapter
- Repeat these steps for the paired or devices making sure each set in broadcast has its own unique network ID
Devices that are in a 1 to 1 control configuration use the Destination address to dictate what other board they talk to so this step is not required for them.
Let me know if you have any questions.
Thank you for the information we will order the Configuration Adapter and give that a shot. If that doesn’t work out for us we will try the RMA. One of the boards that was in the cabinet prior to changing the two cards to mirror cards was a mirror board for another another alarm that was already being mirrored . It was ordered about a year prior which could be why its cross communicating.
Thank you, that programming card worked. We were able to change the network ID to stop the interference.
