1 Product Overview

1.1 Product Function

GT100-EI-RS is an adapter which can realize the mutual conversion between Modbus protocol and EtherNet/IP

protocol. It can connect Modbus (other serial protocol) devices to EtherNet/IP network. Modbus side supports

RS-485/RS-422, and also supports RS-232, it only uses one interface during data communication.

1.2 Product Features

One RS-485/RS-422 or RS-232 interface with independent 1KV photo electric isolation;

Ethernet 10/100M self-adaptive;

IP address conflict detection;

Modbus network communication debug function;

Provide easy-to-use configuration software SST-MI-CFG.

1.3 Technical Specifications

[1] EtherNet/IP network is independent with Modbus network;

[2] Ethernet 10/100M self-adaptive;

[3] IP address conflict detection;

[4] Support ODVA standard EtherNet/IP communication protocol;

[5] Serial: RS-485/RS-422 or RS-232 interface, half-duplex. Baud rate: 1200, 2400, 4800, 9600, 19.2 K, 38.4K,

57.6K and 115.2Kbps can be selected. Parity check mode: None, Odd and Even can be selected, 1 or 2 stop bits;

[6] Acts as Modbus master, it supports 01H, 02H, 03H, 04H, 05H, 06H, 0FH and 10H function codes. It can be

configured up to 48 Modbus commands, 03H and 04H support "Word / Byte mapping" and it is easy to solve the

format conversion problem of big endian and little endian between two network data;

[7] Works under universal mode, it supports character timeout, character number and delimiter control mode, and

has auto sending function;

[9] Max input and output bytes of EtherNet/IP:

Max input bytes: 492 bytes (256 bytes under universal mode);

Max output bytes: 492 bytes (256 bytes under universal mode);

[10] Power: 24VDC (11V~30V), 70mA (24VDC);

[11] Working temperature: -40℉~140℉(-40℃~60℃), relative humidity: 5% ~ 95% (non-condensing);

[12] External Dimensions (W*H*D): 0.98 in*3.94 in *3.54 in (25mm*100mm*90mm);

[13] Installation: 35mm rail;

2.4.3 RS-485/RS-422 Interface

The RS-485 interface of GT100-EI-RS is standard, and the RS-485 characteristics of the product are shown as

follows:

1. The basic characteristics of RS-485 transmission technology

①Network topology: Linear bus, there are active bus termination resistors at both sides.

②Transfer rate: 300 bps~115.2Kbps.

③Media: Shielded twisted-pair cable and also can cancel the shielding, depending on environmental conditions

(EMC).
