TCP/IP cnverters are designed t perate serial prts ver 100M bps Ethernet netwrks. The data is transmitted via TCP/IP prtcl. Therefre, cntrl is available via Ethernet, Intranet and Internet. EX9132C-RS485 cnverter is packaged in a PVC material case well suited fr industrial envirnments. It prvides ne serial RS422/RS485 (Aut- Detect) prt. The serial prt perate in cmmn industrial cnfiguratin. EX9132C-RS485 cnverter is a lw-cst, high perfrmance design. By carefully selecting high quality with cmpetitive prices cmpnents in the wrld, the prducts made netwrk cnnectivity pssible with affrdable cst fr virtually all kinds f devices. EX9132C-RS485 is a serial device server with ne serial RS422/RS485 (Aut-Detect) prt and it prvides ne scket cnnectin prt. This peratin manual will guide yu step by step t learn the varius functins f the EX9132C-RS485 cnverter. The fllwing tpics are cvered in this chapter: Overview Blck Diagram Prduct Features Prduct Specificatins 1.1 Overview EX9132C-RS485 cnverter is designed t make yur industrial serial devices Internet ready instantly. ARM Crtex-M3 CPU f EX9132C-RS485 cnverters makes them the ideal chice fr cnnecting yur RS422 r RS485 serial device such as PLCs, meters, and sensrs t an IP-based Ethernet LAN, making it pssible fr yur sftware t access serial devices anywhere and anytime ver a lcal LAN r the Internet. ARM Crtex-M3 CPU Series cnverters ensure the cmpatibility f netwrk sftware that uses a standard netwrk API (Winsck r BSD Sckets) by prviding TCP Server Mde, TCP Client Mde, and UDP Mde. Mdel EX9132C-RS485 prvides 1 scket cnnectin fr remte management. ARM Crtex-M3 CPU Series Virtual COM driver and sftware that wrks with COM prt can be set up t wrk ver a TCP/IP netwrk in n time. This excellent feature preserves yur sftware investment and let yu enjy the benefit f netwrking yur serial devices instantly. ARM-Crtex-M3 CPU series cnverter supprts manual cnfiguratin via the handy web brwser cnsle and many prtcls including TCP, IP, UDP, HTTP, DHCP, ICMP, and ARP. They are the best slutin t netwrk yur serial devices. 1.2 Package Checklist ARM-Crtex-M3 CPU prducts are shipped with the fllwing items: 1 unit f EX9132C-RS485 cnverter 1 unit f Pwer Adaptr/Supply(9V/12V/24VDC, 500mA): Optinal Quick Installatin Guide in Dcumentatin & Sftware CD Din Rail Munting Kit: Optinal NOTE: Please ntify yur sales representative if any f the abve items is missing r damaged. www.expertdaq.cm EX9132C-RS485 Versin 1.1 21.09.2015 Page 3
1.3 Blck Diagram Lw-cst devices usually are equipped with lw speed prcessrs and limited memries. In reality, they have neither the capability nr practicality t manage cmplicated netwrk TCP/IP prtcls. The ARM Crtex -M3 32-bit prcessr has been specifically develped t prvide a high-perfrmance, lw-cst platfrm fr a brad range f applicatins including micrcntrllers, autmtive bdy systems, and industrial cntrl systems, netwrking by cnverting data stream between netwrk TCP/IP and ppular serial prt signals. Instead f prcessing TCP/IP packets directly, devices need nly deal with thse interface signals, which greatly simplifies the cmplexity f TCP/IP netwrk in linkage. The ARM Crtex-M3 prcessr prvides utstanding cmputatinal perfrmance and exceptinal system respnse t interrupt while meeting lw cst requirements thrugh small cre ftprint, industry leading cde density enabling smaller memries, reducing pin cunt, and lw pwer cnsumptin. The central cre f ARM Crtex-M3 prcessr, based n a 3-stage pipeline Harvard bus architecture, incrprates advanced features including single cycle multiply and hardware divide t deliver an utstanding efficiency f 1.25 DMIPS/MHz. The ARM Crtex-M3 prcessr als implements the new Thumb -2 instructin set architecture, which cmbined with features such as unaligned data strage and atmic bit manipulatin delivers 32-bit perfrmance at a cst equivalent t mdern 8- and 16-bit devices. 1.4 Prduct Features Data Cnversin between RS422/RS485 and Ethernet EX9132C-RS485 cnverter device (RS422 RS485*1 prt) data/signal int the TCP/IP package data/signal and send them ut with the Ethernet Data Stream; r cnvert the TCP/IP package data/signal int serial device data/signal.

3 EX9132C-RS485 Cnverter Cnfiguratin 3.1 Initial IP Cnfiguratin When sett up yur cnverter fr the first time, the first thing yu shuld d is t cnfigure the IP address. This chapter intrduces the methd t cnfigure the device server s IP address. Fr mre details abut netwrk settings, please see the Netwrk Settings sectin in Chapter 4, Web Cnsle Cnfiguratin. The fllwing tpics are cvered in this chapter: Device Management Utility f EXBrwser EXBrwser View EXBrwser Mdify IP EXBrwser Mdify MAC 3.2 Device Management Utility f EXBrwser On PC we prvide a Device Management Utility named EXBrwser.exe which is an executable prgram in Windws 32-bit envirnments. EXBrwser setup tl is used t detect and setup the installed cnverters. It uses UDP bradcast packets t query and cnfigure cnverters n the netwrk. When yu activate the tl, it will detect the existence f the installed cnverters and depict the cnverters status such as IP address, Subnet Mask, MAC Address, and Device ID (see Figure 4.1). The Setup Tl nly can setup ne cnverter at a time. Thus if there are mre than ne cnverter n the netwrk, please shut dwn r discnnect ther cnverters. Otherwise the EXBrwser.exe can nt detect the cnverter. Due t the nature f bradcast UDP packets, EXBrwser has fllwing characteristics: Bradcast packets are nt limited by subnet. Even if the IP address f the cnverters and the cmputer running EXBrwser that d nt belng t the same subnet, it still wrks fine. Bradcast packets can nt pass ruters. EXBrwser can nly be used t mnitr devices with cmputer running EXBrwser in the same segment f lcal area netwrk. 3.3 EXBrwser View View -> Refresh There are tw ways fr refreshing the status f existing devices. Yu may select the item View t refresh the status f existing devices n LAN. Anther is t click the icn as red clr remark as belw. EXBrwser will send anther query t get updated infrmatin.
