Figure 11: Alignment of the UHF transponder, optimized for good read and write capability, here
on the device. The conditions also apply to external antennas.
Mounting and aligning the device and external antennas:
NOTE
Avoid mutual interference when operating several devices
When the reading and writing ranges of several independently operated devices over‐
lap, this can lead to mutual impairment of the system performance of the devices.
To avoid such constellations, the devices offer the following options:
■
When external antennas are used on a device, only one of these antennas com‐
municates on the air interface at a time.
■
Synchronization of multiple devices:
Sync Mode can be used to synchronize the read and write behavior of multiple
devices. For this purpose, the devices are connected to one another via an
Ethernet network. Sync mode then ensures that only one device at a time is
communicating over the air interface for a read or write operation. A defined
device coordinates up to seven subordinate devices.
1. Prepare the base for mounting the bracket of the device, see "Preparing for
assembly", page 29.
Recommendation: Depending on the application it may be possible to use one of
the optional SICK brackets. If necessary, perhaps also in combination with other
brackets
2. At the intended reading point, place an object with transponder within the working
range of the device and/or the external antenna(s) (static object only).
3. Mount the device bracket onto the base.
4. Screw the screws through the bracket into the blind tapped hole of the device.
Slightly tighten screws.
5. If necessary, mount the external antennas in the same manner.
6. Orient the front side of the device and each of the external antennas towards the
object.
