TECO TR3760B: Hardware 


 


 

 



TECO TR3760B thin client

The unit does carry the 'NLYNX' logo on the front panel but has the standard TECO label on the side. The records at Companies House tell me that Nlynx Ltd went into voluntary liquidation at the end of 2015 and was dissolved in October 2017.

My example of the TECO TR3760B was manufactured in May 2014. The TECO web site also shows a TR3760i. As far as I can see this is just a slimmed down (thiner) version of the TR3760B. The second serial port is missing along with the VGA socket and the cutout above the parallel port. It is intended to be directly mounted on the back of a monitor.

Power Supply

My TECO TR3760B came with an external 40W 16V power supply. The label on the TR3760B case says 16V 2.5A. The marking on the back panel adjacent to the power socket says '12V-19V'. The connector is a standard coax 5.5mm/2.1mm plug. I did connect it up to a 12V power source and it worked perfectly.

Expansion

Flash: TECT TR3760B flash memory The Flash memory in the TR3760B is a 1GB 44-pin IDE DOM. Adjacent to the DOM is a SATA data socket next to which is a 2-pin power connector. Also on the circuit board, near the front microphone/headphone sockets, is an unpopulated connector marked JSATA2.

Ram: The RAM is a single DDR3 SO-DIMM. The part supplied was a 1GB ADATA part AD3S1333B1G9-BSSG. I tried a 4GB Elpida part (PC3-12800S-11-10-F3) that worked perfectly.

TECO TR3760B mPCIe socket mPCIe: there is a mini PCIe socket on the board.

USB: The ports are all USB2.0. There are two sockets on the front panel, two on the rear and three internal. The internal sockets are the standard strip-line connectors. One (2 ports) is positioned close to the front of the PCB between the RAM and the audio sockets whilst the other (one port) is just by the two serial sockets.

  • 2 serial port module (COM3 & COM4)
  • USB WLAN module
  • Mini PCI-e WLAN Module
  • Smart Card Reader
  • SATA HDD Module

These would all use the existing onboard connectors.
