INTERCONNECTING PRODUCTS AND CABLES
Miniature Ethernet to Modbus RTU/ASCII Converters ■
Description The tGW-700 series modules are Modbus TCP to RTU/ASCII Device Servers that enable a Modbus/TCP host to communicate with serial Modbus RTU/ASCII devices over a standard Ethernet network. They eliminate the cable length limitation of legacy serial communication devices while overcoming the lack of serial posts on today's computers. The tGW-700 Device Servers are available with seven different serial configurations.

tGW-7xx SPECIFICATIONS The tGW converters are powered by Power over the Ethernet (PoE) or by AC power adapters. POE power is provided by a PoE capable switch like the NS-205PSE using standard category 5 Ethernet cable. When there is no PoE capable switch on site, the tGW Converters can be powered by an optional DC adapter. The module is equipped with a male DE-9 or a removable terminal block connector to allow easy wiring. Based on the tGW-700's amazing tiny form-factor, the tGW-700 achieves maximum space savings that allows it to be easily installed anywhere, even directly embedded into a machine. It also supports automatic RS-485 direction control when sending and receiving data, thereby improving the stability of the RS-485 communication. Optional LED Display Standard units have a single multifunction LED that displays power and LAN connectivity status. Units with a D suffix, i.e. tGW-712D have two extra LEDs for diagnostic purposes. Dual Watchdogs The module contains a dual watchdog, including a CPU watchdog (for hardware functions) and a host watchdog (for software functions). The CPU watchdog automatically resets the CPU if the built-in firmware is operating abnormally, while the host watchdog automatically resets the CPU if there is no communication between the module and the host (PC or PLC) for a predefined period of time (system timeout). The dual watchdog is an important feature that ensures the module operates continuously, even in harsh environments.

POE Compliance
Easy Wiring
The tGW-700 module offers true IEEE 802.3af-compliant (classification, Class 1) Power over Ethernet (PoE) functionality using a standard category 5 Ethernet cable to receive power from a PoE switch such as the NS-205PSE. If there is no PoE switch on site, the module will also accept power input from a DC adapter like P/N 125154. The tGW-700 module is designed for ultra-low power consumption, reducing hidden costs from increasing fuel and electricity prices, especially when you have a large number of modules installed. Reducing the amount of electricity consumed by choosing energy-efficient equipment can have a positive impact on maintaining a green environment.
The tGW-700 module is equipped with a male DE-9 or a removable terminal block connector to allow easy wiring. The Model tGW-712 has a DE-9P connector with lock studs. All the other tGW-700 series modules have a removable screw terminal block for easy connections with just a small screw driver.
