Installation
Controller connection TTL
The TTL port is used to connect a single SAMSON TROVIS 5573 or 5578 Controller, a
SAMSON KT-ELEKTRONIK SOL3 or WPR3 Controller or equivalent device. The controller is
connected with an 8-pole RJ-45 cable (max. cable length: 100 cm) directly to the gateway.
Controller connection over RS-485 bus
One or more controllers or Modbus RTU devices can be connected to the terminals 1 and 2
(RS-485) of the gateway. In this case, the controllers and devices must have an RS-485-
interface (two-wire version) or be fitted with a corresponding converter.
The connection of more than 10 controllers to the RS-485 bus may cause the monthly data
allowance limit to be exceeded. Additional costs may be incurred. Your SAMSON point of
contact can help you in such cases.
Examples:
− Converter for TROVIS 5573/5578: iCon485 (8812-2002)
− Converter for TROVIS 5576/5579: cable converter (1400-8800)
This allows up to 40 controllers or Modbus RTU devices to be connected to a single SAM
HOME Gateway. For the sake of quick access to controller data, we recommend not to make
full use of this specification. In such cases, we recommend using several gateways.
Various RS-485 devices can be connected as part of an RS-485 network to the two-pole ter-
minal. RS-485 network rules concerning stub lines, bus termination and bus bias voltage
must be observed in this case.
Devices with RS-485 interface in four-wire versions can be used. In this case, we recommend
using the CoRe02 Universal Bus Unit (article no. 11996, order no. 1402-1433). When bus
hubs (1400-7140) are used in place of the CoRe02 universal bus unit to connect devices
with RS-485 interface in four-wire versions, the T
A
wire must be jumpered to the R
A
wire and
the T
B
wire jumpered to the R
B
wire.
Digital output (relay)
The digital output (relay) is a floating switching contact at terminals 21 and 22. Small loads
can be switched using this switching output. It can also be connected to a digital input of an-
other device.
Î
Apply a switching voltage (e.g. 230 V AC) to terminal 21 (e.g. using a jumper from ter -
minal 20 (L1)).
