RS232 / RS485 interface converter for connection of SEIKA sensors with RS485 interface to RS232 port of a computer
The interface converter consists of an aluminium housing with a PCB, a 9-channel SubD port for the RS232 bus, a 4-channel clamp for the RS485 bus, a plug for the external 12V supply voltage, two LEDs for monitoring system operation, the bus voltage level and termination resistances and the interface electronics with voltage level converters and transmission line drivers and receivers.
The interface converter connects any SEIKA sensor with RS485 data output interface to the RS232 port of a computer.
