1. Power supply

The factory default setting is +5V(7.5V-12V will inform when placing the

order).By using better ripple factor, KYL-200L transceivers can also share power

supply with other equipment. If possible, a voltage-stabilizing chip with 5V voltage

is more recommended as the only power supply than Switch power supply. But if

only switch power supply available, the jam 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.

2. Connection Definition with terminal

KYL-200L transceivers supply one 9-pin connector (JP1), their definitions and

connection methods with terminals are shown in Table 1.
