IV: How to use the KYL-220
KYL-220 provide RS-232, RS-485 and UART/TTL level interface ports which can
be direct connected with PC, RS485 devices, monolithic processors and other
UART components. Please find the schematic diagram below:
1. Power supply
The factory setting is +5V (needing 3.3V-3.6V, please notify us when placing the
order). Using better ripple factor, KYL-220 transceivers can also share power
supply with other equipment. If possible, a voltage-stabilizing chip with 5V voltage
is much recommended than Switch power supply. But if only switch power supply
is available, the jam caused by switch pulse should be avoided. In addition, the
