Tripod Turnstile Technical Manual
NOTE
Make sure that Power/Network cable is connected to the distribution board.
Network connection
The network connection provides for operational functionality of the Tripod Turnstile. Different
devices in parallel can be connected to the Network Controller by a single unshielded twisted pair
(UTP) cable. Total length of the twisted pair cable is limited to 1 km. One Network Line Terminator
must be connected at the far end of the network cable.
OPTION I:
Connect the twisted pair network cable to designated
terminals. The terminals are marked as “
C_L
”
for network
low signal and “
C_H
”
for network high signal.
OPTION II:
Connect the twisted pair network cable with RJ-45
connector to one of RJ-45 connectors on the “connection
board”.
NOTE FOR OPTION II
There are 2 equivalent UTP connectors for Metra NET Network connection. One can be used as
“trunk line IN” and the other as “trunk line OUT” connector. Take into consideration that if you
disconnect one of the UTP cables (in or out), you also cut off the “trunk line” and devices after this
device will be disconnected from the Metra NET Network. Therefore this type of connection is
recommended only if you use Master and Slave Network Controllers TCP/IP, each on one side of the
“trunk line”.
NOTE
Mind the polarity of the network connection!
Always connect the line terminator at the far end of the network cable!
