Map Descriptor Example 2 – Send a Reset / Ack / Silence Command.
This example illustrates three map descriptors used to send commands to the panel. These are the only active map descriptors that can be used with the Gamewell Serial Driver.
These map descriptors use the WRBX function. When the 1st element (because Data_Array_Offset = 0 ) has its value updated, even if the value doesn’t change, then the driver will send the command to the panel.
Note that you are required to send an Ack before you can send a silence command. The driver does not clear the trigger by setting the array element back to zero. The panel does not send a message acknowledging receipt of the command, thus the driver cannot provide positive confirmation.
Map_Descriptors |
| Data_Array_Name, | Data_Array_Offset, | Length, | Function, | Node_Name, | Gamewell_Func | |||||
Map_Descriptor_Name, | ||||||||||||
Ack_md | , | DA_ACK | , | 0 | , | 1 | , | wrbx | , | panel1 | , | Ack |
Sil_md | , | DA_SILENCE | , | 0 | , | 1 | , | wrbx | , | panel1 | , | Silence |
Res_md | , | DA_RESET | , | 0 | , | 1 | , | wrbx | , | panel1 | , | Reset |
Use one of these keywords.
By using a wrbx you can have the driver send the command when the array is updated.
Thus, to trigger any of these commands have the remote device send a value to the 1st element of the above data arrays.
