How many card formats are supported per controller?

A total of 16 card formats exist on the controller. If using the Asset Management functionality then the upper 8 card formats are used for assets and the lower 8 card formats can be used for access control. If asset management is not being used, then all 16 card formats can be used for access control. Consult your OEM provider for more information on asses management.

Note: Only the lower 8 card formats are currently sent to the SIO modules to be used in degraded (offline) mode for facility code only.

What happens when you press the reset button?

When pressing the reset button on a controller or SIO, you are sending a software reset to the board. The software reset is not a graceful shutdown, it will terminate all processes immediately. When a board does not have a reset button it is recommended to pull the terminal block or POE cable. It is not recommended to pull the jumper that distinguishes between a 12V or POE connection.

Boards that do not have a reset button:

1. LP1501

2. MR62e

Which utility do I use to set a static IP and other network settings on the MR62e?

The MR62e has a built-in web browser interface, similar to the EP and LP series controllers.

Can two MUX8 boards be connected together?

The rule is that two MUX8 boards can be wired in parallel but not in series. So don't try and place one downstream off of another MUX8.

Connecting MUX8 in series is not recommended as daisy chaining will add signal skew and will cause comm problem. Since the mux8 has strong biasing (pull up/pull down) to maintain signal marking when not driven, more than two of them connecting in parallel will overload the RS485 transceiver.

Are the relays on the Mercury boards wet or dry?

The relays are dry contacts.

A dry contact output on a device like a relay means that the contacts have no voltage or potential difference across the two contacts. The contacts simply provide an open or closed state to another device.

A wet contact output on a device like a relay means that when the relay is activated, the relay output contacts supply a voltage to whatever device is connected to the relay output contacts, say for example a light or motor.

What is Controller Data at Rest?

What is it?

Controller Data at Rest is encryption inside the Controller. When enabled, data that is stored is encrypted.

How do you enable the encryption?

1. Login to the controllers webpage

2. Check the checkbox on the Security Options webpage. Note: If a configuration is already in the controller the configuration will be deleted and a new one will have to be sent down.

3. Apply Settings and Reboot

Things to Note:

1. Firmware upgrades will keep encryption intact

2. If you want to disable encryption the only way to do this is to bulk erase the controller.
Note it is possible that the provisioned certificate will be removed during this process. Should this occur the OEM partner will need to contact Mercury to have a replacement certificate issued.

3. When enabling encryption, if the configuration is already present in the controller the configuration will be deleted.

How do I convert firmware from one partner to another partner?

The firmware that Mercury provides is the same firmware for all of the Mercury OEM partners. So there is no need to flash different firmware to the boards when changing over the host software to a different OEM provider.

The only thing unique to each partner is that when the boards are ordered an OEM code is programmed into each board. Each OEM partner has the capability to program their own OEM code into the boards, but not all take advantage of this. You would need to check with the OEM partner to see if they support this ability.

The OEM codes control the look and feel of the web configuration pages as well as the OEM factory default settings. The host software also can validate that the hardware coming online with their software has been programmed with the proper OEM code.

Can Mercury board outputs be used with AC circuits?

Mercury relays can be used on AC with an MOV installed.

However, Mercury products are not UL recognized for use with AC circuits connected to its outputs, and as such, MOV selection has been removed from all install manuals in which UL recognition is no longer retained.

Is SNMP supported on Mercury products?

Yes, SNMP (Simple Network Management Protocol) is supported on Mercury products with an Ethernet port except for the MR51e and MR62e. The EP series controllers supported v2c and the EP4502 and LP Series support both v2c as well as v3.

SNMP is off by default but can be enabled via the web configuration pages.

Mercury does not provide a custom MIB file. The products just use some of the standard networking MIB files. The MIB files include:

Does Mercury Integrate with Aperio Locksets?

Yes, The LP series of controllers supports the following Aperio hubs:

Check with your OEM partner for additional details to confirm they also support this integration.
