The ZLAN ZLSN series serial port to Ethernet module are embedded circuit developed on the basis of core module, including RJ45 Ethernet port and serial ports, serial ports contain TTL level, RS232 and RS485. Can be integrated to user circuit or inside cabinet, have the advantages of small size, easy integration, without making circuit. It can realize the SCM networking and device network upgrade, which is widely used in Security, Industrial Automation, Banking System, Building Control, Intelligent Transportation and other fields.Shanghai ZLAN produces all series of serial products: TTL serial port, rs232/485/422 three-in-one serial port, RS232, RS485, RS485/422, RS232/485, etc. Each kind of serial port has three categories of low power consumption, high stability, high cost performance, refer to core module introduction. There are also multi-serial port and serial port networking module can second-development. ZLAN can meet all-dimensional application demand.
