AH40 (Ethernet)
This chapter describes how to perform a default
configuration of an AH40 communication hub
using the Ethernet interface.
Configuration of the communication hub to
the EAC includes setting jumpers, connecting it
to Ethernet and connecting it to power supply,
according to applicable section below.
Setting jumper for internal/external antenna
Normally the communication hub’s internal
antenna is sufficient. In a difficult installation
environment or if the radio signal needs to be
amplified in a certain direction, an external
antenna can be used. Connect the two left
pins ("EXT") with the jumper to use an external
antenna.
Setting jumper for pariing mode
To activate automatic pairing, connect the two left
pins ("PAIR") with the jumper, see figure.
Connect to supply voltage
Connect the power and ground to the “+” and the
“-“ terminals of the connector marked “8V-24V”.
Note! Power supply input, 8-24 VDC, 3.5 W. The
power supply shall be a Limited Power Source
(LPS) according to EN 60950-1. The power
supply shall be 3 A over current protected. Wire
requirements 16-22 AWG.
Connecting Ethernet
Connect an Ethernet cable to the Hub and make
sure that the Ethernet “LINK” LED is green, which
indicates that the Ethernet link level is established.
The Hub supports 10/100 Mbit/s half and full
duplex with auto-negotiation.
Using Power over Ethernet (PoE)
The communication Hub can also be powered
using Power over Ethernet by connecting it to an
Ethernet switch or other equipment that supports
this.
Due to EMC regulations, do not connect
any other power supply when PoE is used.
