Each one of the last LAN devices of
each termination needs to have LAN
termination LINK as the last device on
the LAN as is indicated above.
If the GEN129 is last devices on the LAN, termination
LINK must be placed on the GEN129 module as well
as each one of the last splitter terminations. If one or
more LAN splitter terminations are not used they can
be left unterminated.
If the GEN129 is not the last LAN device on the LAN from the MU it
will not need to have LAN terminated. However, please note that
each one of the splitter terminations of each GEN129 needs to
have the last LAN device terminated.

Caution:All Genesis devices are electrostatic sensitive devices. As such, all care
should be taken to ensure appropriate procedures are in place when han-
dling and installing Genesis devices. This may include, but is not limited
to wearing an appropriately earthed, conductive wrist strap – to limit
electrostatic discharge into Genesis devices.

Genesis devices.

Genesis LAN (cont):
LAN Termination:
The Master Unit must always be the first device on the
LAN. This device is factory fitted with a 180ΩLAN Termi-
nation Resistor.
LAN Shield:
The shield from the LAN cable should run the length of the
LAN, and should be connected to a communications earth,
at the Master Unit only. The shield terminals on each de-
vice are for connection of shield cables, and do not con-
nect to the device proper in any way
Ensure the cable shield is not connected to any ground or
to any voltage on any device and that the cable shield is
only connected to a communications earth at the Master .
Total of LAN Devices:
Up to 127 additional Genesis devices in total can be con-
nected to the Genesis LAN, across a total LAN length of
up to 1500 meters.
Last LAN Device:
The last device on the Genesis LAN must be fitted with its
termination link. This link fits a 180Ω
resistor to the last device on the LAN.
LAN impedance:
No other devices should have a termination link fitted. If
connected as described above, the LAN should have an
impedance of approximately 15Ω, per 1000 ft, plus the
resistance of the LAN cable when utilising Belden 8723
cable. This may depend on the individual installation. The
same applies for GEN129 LAN splitter on each one of the
four
terminations.
*Don’t test LAN impedance with any devices powered up.
The GEN129 provides 4-way
LAN split terminations
LAN Splitter GEN129:
It is possible to cable your LAN in a 4-way STAR
wiring configuration utilising the GEN129 device.
GEN129 LAN Termination LINKS
When the GEN129 is used termination LINK must be on
the last LAN device of each LAN termination. If the
GEN129 is the last device on the LAN from the MU it also
must have the termination LINK as the last device that is
located on the module. Each one of the 4 x LAN
terminations must be terminated on the last LAN device.

Genesis LAN:
Genesis uses industry standard RS-485 LAN communication to ensure fast efficient
network communication between devices. The Genesis LAN operates at a
communication speed of 19,200 baud between up to 128 devices over a total LAN
distance of up to 1500 meters.
In order to ensure that a high level of performance is achieved, it is necessary to
connect the Genesis LAN in the recommended method.
To this end, it must be twisted pair data cable that is used for the Genesis LAN.
Belden 8723 (RS-485) cable, or equivalent is recommended.
A standard must be applied when wiring from one LAN leg to another. For
example, the A leg on a Master Unit must always be connected to the A legs on
other Genesis devices, while the B leg must always be connected to the B legs on
other Genesis devices.
A very common communication problem is where the A and B lines are reversed.
If this occurs, then some devices may appear on-line, while others are off-line.
The Genesis LAN is an industry standard multi-drop RS-485 configuration.
Do Not Tee Off, or Star configure your LAN. While the LAN may function in these
configurations, Genesis cannot guarantee proper LAN performance.
For STAR configuration please refer to pages 10 and 11 for detailed information on
the LAN distribution module. The LAN module GEN129 is recommended for STAR
wiring when star wiring is required on the site.

Description
The GEN-129 LAN Distribution unit is specifically designed to
provide STAR configuration wiring on the Genesis High speed
RS485 LAN network. The module will provide a STAR connec-
tion up to 4 separate locations from the module. The GEN129
module will also amplify the LAN communication signal for all
devices connected to the unit.
The GEN129 is ideal when your LAN devices are located in
directions where STAR wiring is ideal, or where the existing
site may already have star wiring in place.
Please insure that the LAN termination LINKS are terminated
on the last LAN device of each one of the 4 terminations.

LAN Device mounting:
The LAN Splitter is designed to mount within the HDW-001, metal equip-
ment cabinet. Using this cabinet, it is possible to mount up to 5 LAN
modules within the one cabinet, or any other combination of Genesis
equipment may also be mounted with the cabinet.
The four screws supplied with the LAN module are for
securitng the LAN module to the stand-offs on the HDW-001
Avoid installing the LAN module where it may be exposed to moisture,
either directly (Rain, Sprinklers, Hoses), or by condensation.
