LINK Systems OmniLink II Press Automation Control - Manual (Page 10)

Section 2 Installation
Section 2.1 Preliminary Installation Considerations
1. Before you begin to install your OmniLink II Press Automation Control, you should read this entire
manual carefully. This will help you to understand system functions and plan the installation to save
time and the necessity to rework portions of the installation.
2. The high speed serial bus used to communicate between system modules begins with the OmniLink
II LCD Operator Terminal and goes first to the R/D-Brake Monitor Module located in the back of
the operator terminal enclosure, then on to each optional hardware module used with the system as
shown in Figure 2.1. Every hardware module used with the system has a switch that can be closed
to terminate the serial bus. The termination switch on the module installed at the far end of the
serial bus should be thrown to the closed position. The switches on modules installed between the
operator terminal and the last module should be in the open position. If only one optional module
is used with the system, the termination switch on this module should be thrown to the closed
position. If no optional modules are used with the system, the bus termination switch on the 802-5
R/D-Brake Monitor Module should be thrown to the closed position. The location of the termination
switch for the 802-5 R/D-Brake Monitor Module is shown in Figure 2.1.

3. As shown in Figure 2.2, optional hardware modules may come with one module or multiple modules
per enclosure, depending on the number and type of modules ordered. The modules do not have to
be connected in any particular order on the serial bus, but the serial bus cable must connect to each
module in the daisy chain fashion shown in Figure 2.2. It is desirable to run the cable for the serial
bus to connect the optional hardware modules with the shortest total length of cable. The total
length of serial bus cable used with the system must not exceed 300 feet.
