Converters : SRS-2/4-Z45
The SRS-2/4-Z45 converter module is used to connect MASTER devices with a RS-232 port to a RS-485 bus. The module supports devices, which control Tx switching using the RTS signal and devices, which do not control Tx switching using the RTS signal (Tx switching is then fully automatic). For example, a suitably programmed PC computer can function as the system MASTER device.
