1. The ZENO
®
-3200 receives a CCSAIL message.
2. The ZENO
®
-3200 checks whether the Source Address of the received message is the same as the
Network Source Address and if the Destination Address is one of the specified remote ZENO
®
-3200
addresses. If the check fails, it proceeds to step #5; otherwise, it proceeds to step #3.
3. The ZENO
®
-3200 checks the received CCSAIL message to see if it contains a repeatable command.
If so, it proceeds to step #4; otherwise, it does nothing further.
4. The ZENO
®
-3200 changes the Source Address of the received message to its Primary Unit ID. The
ZENO
®
-3200 then calculates a new CCSAIL message checksum and transmits the modified CCSAIL
message on the same COM port that the original message was received. The procedure ends.
5. The ZENO
®
-3200 checks whether the Source Address of the received message is one of the specified
remote ZENO
®
-3200 addresses and if the Destination Address is the same as its Primary Unit ID. If
the check fails, the procedure ends; otherwise, it proceeds to step #6.
6. The ZENO
®
-3200 checks whether the received CCSAIL message contains data. If so, it proceeds to
step #7; otherwise, it does nothing further.
7. The ZENO
®
-3200 changes the Destination Address of the received message to the Network Source
Address. The ZENO
®
-3200 then calculates a new CCSAIL message checksum and transmits the
modified CCSAIL message on the same COM port that the original message was received. The
procedure ends.
If the host needs to send a command intended for the repeater itself, it simply sets the destination address
of its message to the Primary Unit ID of the repeater.
A ZENO
®
-3200 that is set up to be a repeater can continue its primary
function of data collection with any suite of supported sensors.
As an example, a host with a CCSAIL address of 1 wants to communicate with 4 remote ZENO
®
-3200s
whose addresses are 1010, 1020, 1030 and 1040. There is no direct LOS between the host and the
remotes, but another ZENO
®
-3200 with address 500 has LOS with the host and all the remotes. The
ZENO
®
-3200 with address 500 will be set up as a repeater by setting the Network Source Address to 1
and setting the first four remote addresses as 1010, 1020, 1030 and 1040. A secondary host must also talk
to the remotes and to the repeater. If its address is 10, then the Alternate Source Address in the repeater
ZENO
®
-3200 is also set to 10.
