1. Power supply

The factory setting is +5V (needing 7.5V-12V, please notify us when placing the 
order). Using  better  ripple  factor,  KYL-300L transceivers  can  also  share  power 
supply with other equipment. If possible, a voltage-stabilizing chip with 5V voltage 
is much more 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 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.

Connection Definition with terminal

KYL-300L transceivers  supply  one  9-pin  connector  (JP1),  their  definitions  and 
connection methods with terminals are shown in Table 1.
