Chapter 7 – Mounting
Only one transponder may be in the reading range of the antenna at any time.
Mount the transponders as horizontally (disc transponders) or vertically (rod
transponders) as possible.
7.2 Preparation of Connection Cables
The antenna has three connectors.
Connection cables are not part of the scope of delivery. Suitable cable types are
available from Götting (see 3.1 „Required Accessories“ on page 13). Compatible ca
-
bles are also available from many manufacturers. Cables must be used that are suit
-
able in terms of impedance and have a shield.
7.2.1 Connecting X1 (Power)
The POWER connection contains the voltage supply, the USB interface and the po
-
sitioning pulse. The output for the positioning pulse is supplied via +Ub and is limited
to 20 mA.
If you want to use the USB interface:
Refer to chapter 9 on page 31.
7.2.2 Connecting X2 & X3 – CAN Bus
The CAN bus is connected to the antenna via two connectors. These connections
can be used for voltage supply. They are labeled X2 and X3 and have the following
pin allocations:
