Field Report: Burk GSC3000
G-Link expansion series
Burk has recently expanded the capability of the GSC3000 by leveraging its G-Bus RS-485 communications network. Burk calls the expanded product line G-Link. It includes the GX-128 Interface for X10 automation, a pair of remote outlet controllers, the GT-4 Remote Temperature Monitor and the One Connect system that provides a direct interface for Nautel V5 and V10 transmitters.
The Burk AC-8 and AC-4 bring the power cycle into the GSC3000 realm of capability. The AC-8 and AC-4 are operationally identical. The differences being that the AC-8 is an eight-outlet rack mounted unit matching the look and size of the GSC3000. It features front panel outlet controls with status LEDs, while the AC-4 is much smaller. Having only four outlets, the AC-4 can be easily stowed in the bottom of a crowded equipment rack or wall mounted.
The One Connect is the first of its kind. Burk has found common ground with transmitter manufacturer Nautel allowing nearly direct integration with its V5 and V10 transmitters. Rather than using individual wires to connect to the transmitters metering samples, status indicators and command controls, Burk's One Connect receives info directly from the transmitters control CPU via a serial RS-232 connection. By taking advantage of a direct connection, Burk One Connect brings much more data to the GSC3000 than most engineers would ever dream of bringing to a conventional remote control.
The Burk GT-4 Remote Temperature Monitor is simple and straightforward. It allows four temperature probes to be connected and monitored via G-Bus by the GSC3000. Three types of temp sensors are available: indoor, stack and outdoor/general purpose. An outdoor/general purpose sensor is included.
The GX-128 brings monitoring and control of X10 compatible automation modules to the GSC3000 product. X10 is a specification for wireless consumer-oriented appliance, lighting and security equipment. Quoting X10.com, “X10 is regarded as the de facto standard in home automation.” 128 X10 modules can be paired to the GX-128.
My facilities use seven of Burk's GSC3000 equipment, so I couldn't resist trying out a few AC-8s. Our tech ops room is strictly secure, so anyone needing to reboot an errant ISDN unit had better be on the engineering staff. Knowing that these things often catch a bug, I plugged them in to the AC-8's rear panel. I also plugged in the occasionally cranky POTS codecs as well as a few of the other usual suspects (PCs).
I've used the GCS3000 product since its introduction. Burk is interested in improving and further evolving the product, so I can't wait to see what they come up with next.
