III. How to use KYL-300H
KYL-300H can provides RS-232,RS-485 and TTL level interface port for direct connection
with PC, RS485 devices, monolithic processors. The schematic diagram is shown below:

Power supply
The factory default setting is +12,
±1
.2V DC. By using better ripple factor, KYL-300H
transceivers can also share power supply with other equipment. If possible, a
voltage-stabilizing chip with 12V voltage is much more recommended than Switch
power supply. But if only switch power supply available, the jam caused by switch
pulse to the transceivers should be avoided. In addition, the reliable grounding must be
used if there is other device in the system equipment. In case of failing to connect with
the ground, it can form its own grounding but must be absolutely separated from the
municipal electric supply.
