 A1 * Group Numbering

See graphics in the chapter "Electrical Installation".

Overview y The first three octets of the GW-MP device’s IP address are SW programmable, and
the fourth octet is presettable by the hex code switches (3, 4) on the GW-MP front
panel.
y The fourth octet is identical to the number of the elevator group to which the GW-MP
device is connected.
y Some settings are forbidden. Refer to the group number table below for examples of
address settings and for the forbidden settings.
y Always reset the GW-MP device by pressing the Reset button (1) when the setting of
the hex code switches (3, 4) has been changed because the setting of the hex code
switches is read during boot-up only.
y In case a GW-MP device cannot be accessed via terminal because its IP address is not
known, for example after transferring a device from one installation to another, the
following recovery procedure applies:
– Preset the hex code switches to "00" and reset the device.
This sets the IP address of the GW-MP device to 192.168.10.253.
– Access the GW-MP device via the IP address above and re-program the device’s IP
address as desired.

 A2 * Ethernet Basics

Standard Ethernet supports data transfer at the rate of 10 Megabits per second (Mbps).
As the performance needs of LANs increased in time, the industry created additional
Ethernet specifications for Fast Ethernet and Gigabit Ethernet. Fast Ethernet extends
standard Ethernet performance to up to 100 Mbps and Gigabit Ethernet to up to 1000 Mbps.
For BMS clients, standard Ethernet is fast enough. However, with regard to elevator life
cycles, cables have to be prepared for 100 Mbps, that means category 5 (CAT5) shielded
twisted pair (UTP) cables and 10/100 Mbps switches.
The most common form of standard Ethernet is 10Base-T, which offers better electrical
properties than Thicknet or Thinnet because 10Base-T cables:
y Utilize UTP cables rather than coaxial cables.
y Prove more cost-effective than alternatives like fiber optic cables.
In addition to cable types, another important aspect of Ethernet networking is the segment
length. A segment is a network connection made by a single unbroken network cable.
Ethernet cables and segments can only span a limited physical distance, beyond which
transmissions will likely fail due to line noise, reduced signal strength and other
degradation. Ethernet cable specifications and manufacturers of Ethernet equipment are
required to meet the a minimum specifications for segment length. Typical values are
provided in the table below.
Ethernet cables are manufactured to any of several standard specifications, the most
popular Ethernet cable in current use is CAT5 which supports both Standard and Fast
Ethernet.

Description Segment Length Cable

10Base-T / 100Base-T 100 m CAT5 UTP
10Base-FL 2000 m Fiber optic
Additional hardware necessary
Segment Lengths
There are various ways of building a proper Ethernet building network. The configurations
shown below describe the basic Ethernet topology as applied to BMS clients wired to
Miconic MX-GC elevator controllers.
For network segment connections, it is recommended to use network segment switches
(NSS) instead of hubs.

If a GW-MP device is connected to a BMS client directly, use an Ethernet cross cable.
