12.2.3 GPIO
– RELAYS
These are the four GPIO Output relays
12.2.4 GPIO-OPTOS
These are four GPIO opto-isolated inputs. V/G is used to power the optos from either internal or external power.
12.2.5 RJ45
– PoE
The primary CobraNet network connection. Also provides PoE power input.
12.2.6 RJ45
– SECONDARY
The secondary CobraNet network connection, when using a redundant CobraNet network. Does not provide PoE
power input.
12.2.7 5V DC Jack
Provides input for an ex5V @ 2A power supply (supplied with the unit)
13 HARDWARE INSTALLATION
13.1 Mounting
13.1.1 Flange Mounting
The Hono Mini CobraNet interface mounts using the flanges on the side of the unit
13.1.2 Rack Mounting
The Hono Mini CobraNet interface can be rack mounted using the optional rackmount bracket (p/n ENC2305).
This bracket can mount up to two Hono Minis.
13.2 Ethernet Connection
There are two RJ-45 Ethernet jacks on the rear of the unit. If a redundant CobraNet network is not being used
then plug a network cable into the PRIMARY jack. If a redundant network is being used then plug a second
network cable into the SECONDARY jack. (See
http://cobranet.info/support/design/switched_networks
information on redundant networks.)
A CAT-5 or better (CAT-5e, CAT-6 etc) network cable is required for 100baseT Ethernet operation. The cable
length between the Hono Mini interface and a network switch should not exceed 100 meters (328 feet)
