6.6 Operation Policy
In the operation of devices control and status request through the CG102RS232, following
policies are strongly recommended.
In the operation of single device control/status request, the CG102RS232 will response to
the external system within two seconds (refer as the Operation Period) when receiving the
request from external system. The interval of Operation Period is depending on the traffic
loading of ZigBee network and distance of the target device. The external system is not
recommended to send any request to CG102RS232 within the Operation Period. Under
normal operation:
-
if the target device is reachable by the CG102RS232 directly, the CG102RS232 may
response to the external system within 0.5 second;
-
if the target device is reachable by the CG102RS232 through multiple ZigBee network
hops, the CG102RS232 may response to the external system within two seconds;
-
if the target device is unreachable by the ZigBee network, the CG102RS232 will
response to the external system after two seconds with the FAILURE response.
After the external system received the response from CG102RS232, the external system
may send another request to the CG102RS232 immediately.
