Self-Tuner ASIC Inside On All RS-485 Port
• 2-wire RS-485
->half-duplex network
-> send/receive direction control.
• Self-Tuner ASIC controller
->auto detect & control the send/receive direction of RS485 network
• The 8000 family equips a Self-Tuner ASIC controller
on all RS-485 ports(COM 2/3 of 841x/881x, 8142 &
8144).
ToCom(port, sent_data);/* send one sent_char to RS-232/RS-485
