Page 3: General Information
1.1. WARRANTED INFORMATION ADA-4040PC3 converter is covered by a two year warranty from date of sale. In case of being damaged it will be repair or the damaged component will be replace. The warranty does not cover damage caused from improper use, materials consumption or any unauthorized changes. -
Page 4: Description
RS485 bus. Galvanic isolation of ADA-4040PC3, protect the system structured on RS422/485 bus and increases its reliability. ADA-4040PC3 supports the asynchronous baud rate up to 230.4 kbps through four or two pairs of twisted-pair cables connected to screw terminals. The converter use RX+, RX-, TX+/A, TX-/B lines for functioning. It is possible to connect 32 devises to RS485/RS422 network constructed on base of ADA-4040PC3, working at the half duplex or full duplex mode. -

FACTORY DEFAULT In case of faulty functioning ADA-4040PC3, can be restored the factory default setting of the converter internal registers. Set SW1 microswitch mode as in the table below. SW1-1 SW1-2 Disconnect the power and after while connect again the power. -
Page 10: Emergency Firmware Update
SW1-2 After microswitch setting, should be restarted ADA-4040PC3, by turning OFF and then ON the power supply. The yellow LED will light continuously and the converter will be in Emergency Firmware Update mode. Now follow the description in the above point. -
