Connection and adaptation

Communication interface details

RS485 interface (COM1): Complies with Indramat standards, supports bus topology, and can connect up to 2 BTV04 on a single bus. It requires the use of INS0619/K01 connectors with terminal resistors.

RS232 interface (COM2): Used for connecting with PC, only supports point-to-point communication, mainly used for firmware download and debugging.

Debugging and operation process

First debugging preparation

Hardware: BTV04 host, 24V power supply, IKB0012 connection cable, PC (installed with Windows 3.11/95/98/NT).

Software: Dolfi download tool (SWD-DOL * PC-INB-01VRS-MS-C1,44), BTV04 application firmware.

Debugging steps

Connect the RS232 interface (X3) of BTV04 to the COM port of the PC using IKB0012 cable.

Supply power to BTV04 (24VDC) and display IndramatLogo upon power on.

Start the PC Dolfi software, select COM port, baud rate 9600bps, and receive address 03.

Click on “Serial Connect” to establish a connection, and select “Backup” to back up the original firmware (if needed).

Select ‘Serial Send’ to load the new firmware, the progress bar displays the transfer status, and after completion, it prompts’ Programming successful ‘.

Click on ‘Serial Disconnect’ to disconnect, and BTV04 will automatically restart and run the new firmware.

Startup and maintenance mode

Normal startup: After powering on, check the firmware integrity → turn off the LED → start the application.

Maintenance mode: Before starting the application after power on, press the F1 key → display the boot program and firmware version → to perform firmware updates or troubleshooting.
