When operating multiple RC4Magic-900 systems in the same space, it’s important that they use different RF Frequency Masks. This is in addition to using different Private System IDs. Your IDs are private, but masks are not, simply because everyone must work with the same available RF bandwidth.

If you’re in this position, the easiest solution is to use the buttons on the devices to select different IDs, which each have a different RF Frequency Mask by default.  For example, if you are using your Private ID code for ID0, and somebody else is using their Private ID for ID0, the codes are different but the frequencies being used are the same. By selecting ID1 on one of those systems, you will now be using different frequencies and the interference problem will cease.

Using up to 4 system at once, there are 4 different frequency masks available, but you must run one system on the Public ID, which is marginally less secure than a Private ID.  To avoid that concern, or to operate more than 4 systems at once, you will need to use our RC4 Commander configuration software.

It provides various features to address your need:
– It provides 8 different “default” or preset frequency masks that you can mix-and-match with your ID codes.
– It provides a tool for creating completely custom frequency masks (this is rarely if ever needed, but it’s there).

Next time you are going into a situation like this, give us a heads-up in advance (submit a tech support ticket) and we can help you prepare in advance.

If you can’t coordinate with other users, you can usually assume they will be using default channel masks.

If you use Commander software to use any of the other masks we provide, the non-default ones, you will most likely avoid any conflicts.
