5 Configuration and Connection of Cables
AH15 (RS-485)
This chapter describes how to perform a default
configuration of an AH15 communication hub
using the RS-485 interface.
Configuration of the communication hub to the
EAC includes setting the DIP switches, connecting
it to the RS-485 bus and connecting it to power
supply, according to the applicable section below.

DIP 1-5 – Selecting the EAC address/Automatic
paring
The DIP 1-5 has two functions, either automatic
paring mode, or manual selection of EAC address
on the RS485. Default configuration is to select
an address according to below. By doing so
automatic pairing will be deactivated.
∙
DIP 1-5 – Pairing mode
If DIP 1-5 are set to OFF, pairing mode will be
activated. This means that after powering on
the communication hub it will automatically
try to pair with locks within range. Automatic
pairing will only be made with unpaired locks.
The automatic pairing procedure is described in
ref [2], Aperio Online Programming Application
manual.
∙
DIP 1-5 – Selecting EAC address
It is possible to select an address 1-31 for the
AH15 communication hub using the DIP switch.
For mixed modes, see section
"Selecting the
correct EAC address (AH15/AH30)" on page 42
for more details and advance options.
The communication hub must be power
cycled after changing the address, since
the state of the DIP switch is read only at
startup.
