== Description ==
TEL-SERDB9 SERX4 Provides USB to Multiprotocol(RS-232, RS-485-Half Duplex, RS485-Full Duplex) serial connection (up to 4 Ports per TEL).
* Single CAN device Simple USB Connection protocol * Supports CAN 2Multiprotocol implementation on one DB9 Connector.0A Specifications* Supports ISO 11898Individually enabled between RS-2 232 or RS485 ports. * Build-in Termination resistor.* Up too 1Mbit/s bit rateProtocol switching using Onboard switches or using I2C expander
