4.11.7 Interface INTRE-C – RS485/TTL.

In the RS485/TTL field, the communication parameters of the interface may be manually set. To enable the

establishment of communication between the PSU and the interface, the communication parameters must be

identical in both devices.

If communication takes place between a PSU and an INTE-C interface, the connection speed

setting may be omitted. Full connection configuration, including the address and speed, is performed

using the „Detection” function, as described in the section „INTE-C Interface – Detection”.

Fig. 31. Communication parameters setting.

In order to confirm the introduced changes, press „Save”.

4.12 Interface INTRE-C – Detection.

In the „Detection” tab, functions enabling detection of PSUs connected to the interface and their

appropriate configuration for work can be found.

The INTE-C interface only cooperates with one PSU, so one item will appear on the list of the

detected PSUs.

The INTRE-C interface is connected to a RS485 bus and cooperates with up to 247 PSUs;

this is the maximum number of items which may appear on the list.

Fig. 32. „Detection” tab.

The first step to perform is to search the PSUs connected to the interface. Upon pressing the „Detect

Devices” button, the interface will perform an arbitration procedure. All PSUs properly connected to the bus will be

detected and will appear on the list of devices. All devices physically connected to the bus should appear on the

list. If the list is incomplete, check whether the devices are correctly connected and repeat the search process.
