Delaying the response time
The response time of the PAC1020 may have to be delayed to enable its operation as a slave
device with devices from other manufacturers on the bus. The PAC1020 can automatically
calculate the response time to suit the baud rate. This automatic calculation is set at the
factory. The delay time is individually adjustable between 1 ms and 255 ms.
Polarization
Polarization of the RS485 data lines must be implemented at another point on the bus. The
PAC1020 does not contain polarization resistors.
