Inter Message Delay

Some installations require a “pause” between adjacent messages to allow time for the Z-Wave interface to “catch up” with its own internal processing. This has the effect of adding time between polls, so this number should be kept as small as possible. Normally, a setting of “0.0” will work.

Serial Port Config

Communications parameters are set here to match the set up of the Z-Wave serial gateway’s RS-232 port. See To set the ZWaveNetwork communications parameters.

Zw Ack Timeout

Number of 10 millisecond ticks that the Z-Wave gateway waits for an ACK before timeout.

Zw Byte Timeout

Number of 10 milliseconds ticks that the Z-Wave gateway waits for a new byte received, once a received frame has been detected, before timeout.

Zw Version

Serial API version of the Z-Wave gateway.

Zw Compatibility

Contains a number of read-only status properties that reflect serial API functions supported.

Configure As Sis

When set to true (default), the JACE attempts to establish the interface as the SIS for the Z-Wave network. Otherwise, it attempts to establish the interface as the SUC for the Z-Wave network.

Home Id

(read-only) The 24 bit Home ID for this Z-Wave network. This is automatically initialized during replication from a Z-Wave primary controller.

Interface Node Id

(read-only) The node ID of the Z-Wave interface (JACE Z-Wave option card, or external Z-Wave serial gateway). This is automatically initialized upon replication from a Z-Wave primary controller. If the JACE has been correctly installed as an SIS or SUC, this value should be 2.

Is Primary Controller

(read-only) If true, indicates that the interface is acting as the primary controller for the network. This is an indication that the interface is acting as an SIS.

Interface Capabilities

Contains a number of read-only status properties that reflect the Z-Wave interface’s operating mode. If operating as an SIS, all properties should be true except “Is Secondary”, as shown in Figure 4. The “Is Secondary” property is true only if the JACE is not installed as an SIS or SUC, but instead a Static Controller. For related details, see About JACE Z-Wave operation modes.

Use Node Names

Default is false. If set to true, the driver automatically creates a display name for each device that also supports the “Naming” command class (Node Name and Node Location). The display name is a combination of the device’s location and the name strings, along with node ID number.

For example if device (node 7) named “Kitchen_AC_R” has a Node Name of “CoffeePot” and Node Location of “Kitchen”, and this property is set true, it will appear listed in all views as:

Kitchen_CoffeePot_7 (instead of Kitchen_AC_R)

If present, display names are used throughout views and dialogs instead of component names.

If set true, any device that does not support the Naming command class appears instead using a combination of its “specificDeviceClass” and node ID number. For example a device (node 3) named “Thermostat” might instead appear as “thermostatGeneralV2_3”. Find a device’s specific device class string under its “Node Info” container slot.

Auto Associate

If true (the default), the driver automatically creates an association to the JACE for all association groups supported by a device. This causes the data that is sent as the result of the association group event to update in the JACE, without waiting for the device to be polled.

Auto Route

If true (the default) the driver uses an “auto-route transmit option” when sending messages. This option causes the Z-Wave interface / option card to try transmitting messages via other repeater nodes if communications fails. Be careful about changing this property, unless you are sure all nodes can be accessed via direct communications.

Read Back Time

Specifies the amount of time, in milliseconds, after a Z-Wave writable point sends a write message to a device that it triggers a subsequent read message to be sent to the device (to update that point's read value). Setting the value to 0 disables this feature.
