GCT - Serial Link

GCT-SLink provides 4 port RS232 and 1 port 10/100Base-Tx Ethernet, can focus manage disperse serial devices, through an IP network.

GCT-SLink allows a "remote" serial port for any LAN connected workstation via telnet or port-redirector software. It also connects any two async serial devices through a LAN, even via routers, when used in client-server or  direct mode. It is often used with serial devices such as remote data collection terminals, DCB multiplexers and Access Switches, SCADA, building automation equipment, UPS's, bar code scanners, or climate control devices. It is used to connect serial management ports directly to an Ethernet network for "in-band" control of "out-of-band" devices. For this application, simply telnet to the serial management port of the connected device or use inexpensive (or free) port redirector software.

GCT iSpeak

GCT- i Speak is a SIP compliant wall mount indoor/outdoor speaker designed for voice paging, loud ringing, and emergency/ safety/security notification and alerting. The speaker is PoE enabled and equipped with a high efficiency integrated audio amplifier, Common application environments include: classroom, factory warehouse, utility plant, machine shop, garage, lunch room, kitchen, etc. IP speakers function as a paging system that can broadcast and multi-cast live messages and recordings to target specific rooms, areas, buildings, or campus, overriding any background music or other audio of a lower priority.

Wide-band OPUS codec (HD voice and music) and other existing compatible codec are supported in the speaker to provide optimum speech clarity and intelligibility and high-fidelity music. Voice paging and emergency announcements can be easier to understand with wide-band, particularly in a noisy environment.

The speaker registers as a 3rd party SIP endpoint with most standard VoIP telephone systems. A single registered speaker can be configured to steam audio to any predefined number.

GCT-iSpeak (Wideband IP Speaker)

System Overview
GCT- i Speak is a SIP compliant wall mount indoor/outdoor speaker designed for voice paging, loud ringing, and emergency/ safety/security notification and alerting. The speaker is PoE enabled and equipped with a high efficiency integrated audio amplifier, Common application environments include: classroom, factory warehouse, utility plant, machine shop, garage, lunch room, kitchen, etc. IP speakers function as a paging system that can broadcast and multi-cast live messages and recordings to target specific rooms, areas, buildings, or campus, overriding any background music or other audio of a lower priority.

Wide-band OPUS codec (HD voice and music) and other existing compatible codec are supported in the speaker to provide optimum speech clarity and intelligibility and high-fidelity music. Voice paging and emergency announcements can be easier to understand with wideband, particularly in a noisy environment.

The speaker registers as a 3rd party SIP endpoint with most standard VoIP telephone systems. A single registered speaker can be configured to steam audio to any predefined number.

For multi-cast paging applications zone paging is supported via key press selection from standard IP phones. An integrated microphone in the speaker enables talk-back. Built-in microphones and speakers on IP devices enable intercom functionality with two-way communication. Initiate a call with a push of a button, and speak between a phone and the device, or between devices. The IP Speaker functions as a durable, weather-resistant, surface-mount PoE loud-speaker that extends the reach of audio communication to indoor/outdoor environments

Any combination of IP endpoints can be deployed from one to many. There is no limit to the scale of the solution.

The GCT- iSpeak comes with a built in microphone, high efficiency audio amplifier and a high quality loudspeaker. The endpoints are PoE (48V, IEEE802.3af, Class 0) enabled and connect to the network via standard RJ45 connector. Only a PoE switch or injector is required to power the endpoints, and network connectivity to SIP server is all that is needed. No other hardware or software is required to operate the paging system. This devices can operate standalone. They do not require external software for atomic timekeeping or broadcasting messages from the device’s web server. However, you can use application software to take advantage of the device capabilities, and then integrate the devices into applications like a mass notification system, a phone network etc.

It is used to connect serial management ports directly to an Ethernet network for "in-band" control of "out-of-band" devices. For this application, simply telnet to the serial management port of the connected device or use inexpensive (or free) port redirector software.

GCT-SLink uses the TCP/IP protocol, allowing data connection across routed or switched LAN/WAN networks as well as connections on a local network.

GCT-SLink supports serial interface speeds up to 230 Kbps. It can automatically open connections when it powers up (Nailed-Up mode), eliminating the need for a manual request. Full flow controls (RTS/CTS) and Xon/Xoff are also supported.

GCT-SLink also allows a serial device to treat the modem as a true "Ethernet Modem", using normal modem control and response strings such as "ATD", "ATE", +++, etc. This allows a single modem to connect to multiple remote servers  under control of the attached serial device.

Reverse Telnet (Telnet Client) mode allows telnet functionality to be added to serial devices.
If in point to point client server mode and the "nailed" connection is lost, it automatically reconnects when a path again becomes available.

GCT-SLink can be managed directly through its physical port as well as remotely from other network locations. Remote configuration is supported using TCP/IP (telnet) or with the easy web browser interface. Security lists are provided for management security. supports RFC 2217 (remote control of serial port parameters), with a compliant client.
