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-500L transceivers supply one 9-pin connector (JP1), their definitions and
connection methods with terminals are shown in Table 1.

9. The attentions of data transmission
a. The delay time (tc) of conversion between transmitting and receiving is less than
1ms.
Timing diagram:
b. The delay time of transceivers between the first bit sent by TxD to the first
bit received by RxD.
Due to a data processing will be made on user’s data by KYL-500L transceiver
using FEC (Forward Error Correction) or other correction algorithm, when RxD
of a KYL-500L transceiver ‘A’ receives the data, then transmits it, the other one
transceiver ‘B’ will have a delay (ts) to receive and transmit by TxD. Different
RF data rate causes different delay time. Please see the specific delay time
below:
