I/O Modules for Ethernet 

Description and technical parameters 

LAN-485 is input / output modules for transmission of contacts and RS485 data over ethernet. Management software provides the 

option of contact functions remote setting, e.g. negation, output activity length timing, logical sum etc. RS485/RS422 port supports 

communication types: point-to-point, bus and EXP-C mode enabling connection of up to 15 EXP-C units to the RS485 port. 

Every EXP-C(16) module extends the number of input and output contacts by 6(16x DI and 8x TTL OUT).

Installation and Setting 

1. Converter mounting 

Mount the converter according to modification: 

Modification DIN - to DIN35 

Modification RACK - to 19˝ rack RACK/3U 

5. Setting of half / full duplex of RS485/RS422 port 

Modification DIN and RACK - in SIMULand software / 

menu „Bus“ / option „Port“ choose mode 

„RS485“ - half duplex or „RS422“ - full duplex. 

2. Connect supply

12/24VAC 

6. Setting of mode for connection of IO modules EXP-C 

- in SIMULand software / menu „Bus“/ option „Mode“ set 

mode „EXP-C“ (offset 0). After that it is possible to 

Connect up to 15 IO modules EXP-C to the port. 

7. Termination of RS485/RS422 port 

Modification DIN and RACK – for termination of A/B 

and Y/Z wires use DIP1 and 2 switches. See the 

pictures on the following pages. 

Modification RACK – the converter is automatically 

connected to supply by pushing into 19˝ rack RACK/3U. 

The converters are compatible with RACK/3U-SU and 

RACK/PoE racks. 

3. Ground overvoltage protections 

Modification DIN – see the picture below. 

1.5mm 2 

Modification RACK - overvoltage protections are 

automatically grounded when inserted into the 19˝rack. 

4. Connect the LAN-485 converter to the PC 

Launch the SIMULand application and set the 

converter. The latest software version and application 

notes could be downloaded from:

8. LAN-485 address setting 

- set on devices DIN – DIP, RACK 

LAN-485 is addressed to an address different from 0 

only if we want to use it as a virtual device EXP-C. 

In standard cases the address is always 0 (default). 

9. Address setting 

The values are set in binary system.

High response speed is one of the basic features of LAN-485. For devices, that need fast response in two-way communication, you can 

create data bus over the mode UDP (multicast). Approximate delay times on the data line are 4 ms at transmission speed 9.6 kbps and 

3.7 ms at speed 19.2 kbps.

* When interconnecting the RS485/RS422 buses of 

alarm systems we recommend using only our LAN485 

and LAN-RING devices optimized for low delays of 

RS485/RS422 transmission. See www.metel.eu for an 

up-to-date list of compatible systems that have been 

tested with our devices. 

Default device IP 

address is 

provided on the 

label 

NOTE: If you can not connect to the device check the IP address of the network adapter in your computer; it must be set in the 

range of the device IP address. 

E.g.: device IP address: 10.0.0.1 PC IP address: 10.0.0.2-254 

mask: 255.0.0.0 mask: 255.0.0.0 

Setting of RS485/RS422 transmission in UDP mode (multicast) 

The setting is very simple and consists of the following steps: 

1. In menu „Bus/Mode“ set the system you are using. If not provided select „RS485” or „RS422". If the system is provided in the 

menu no further setting in menu „Bus“ is needed. The converter sets it automatically. 

2. In menu „Ethernet“ set receiving and transmitting addresses in range 239.0.0.0 - 239.255.255.255 (multicast). 

topology BUS – set the same receiving and transmitting address on all converters. 

topology POINT-to-POINT – set the addresses “crosswise”: 

Example: Device 1 receiving address - 239.192.168.2, transmitting address 1 - 239.192.168.3 

Device 2receiving address - 239.192.168.3, transmitting address 1 - 239.192.168.2
