Boundary scan controller
for Fast Ethernet
The Goepel Electronic LAN 1149.1 is the first boundary scan controller for Fast Ethernet (IEEE802.3)
The Goepel Electronic LAN 1149.1 is the first boundary scan controller for Fast Ethernet (IEEE802.3), and the first member of a complete product family for boundary scan test and in-system programming based on local area networks. The LAN controller opens up the infrastructure of high speed networks and the Internet to engineers which will revolutionise working practice.

Available from UK distributor BSE UK, the LAN 1149.1 controller when combined with Cascon's floating licence feature allows test and ISP programming, debugging and execution to be controlled from any Windows workstation on an organisation's network.
Using this feature engineers can remotely test and diagnose boundary scan operations from their desktop and allows, for example, problems in production to be directly debugged without the need to leave the office.
The LAN 1149.1 includes a 32bit PIO to control signals on the unit under test (UUT) which are not accessible by boundary scan, TCK frequency programmable from 100kHz to 30MHz, a two-wire handshake bus for external synchronisation of scan operations and two independent test access ports (TAPs) with I/O levels which are programmable from 1.8 to 3.6V enabling it to interface to different logic levels without the need for external signal conditioning units such as PODs.
To increase productivity the unit also has a gang feature that can be used to test and program up to eight boards in parallel.
At the heart of the LAN 1149.1 is the SPACE (scan power acceleration by cellular encoding) scan architecture providing sustained data throughput of up to 30Mbit/s for in-system programming of Flash memories.

Board programmer integrates with production ATE
The ImageWriter is a modular, board-level programmer that can be embedded into a board fixture on an ATE system, activate on command and program a single board or multiple-board panels
Throughput is maintained regardless of the size of Flash allowing the controller to be used for next-generation Flash memories.
Another feature of the SPACE architecture is the Dualscan feature which can simultaneously execute serial and parallel vector operations using the 32bit PIO.
This gives added boundary scan efficiency and a significant increase in programming throughput.
Another feature of SPACE is the integrated active delay compensation (ADYCS) that compensates for delays occurring on the test-bus wiring and UUT scan path during TAP signal transmission.
ADYCS prevents the reduction in TCK frequency and data throughput which traditionally results from long scan paths.
The advanced features of the LAN 1149.1 are fully supported by the leading System Cascon and Polaris packages making it compatible with all common industry-standard vector formats including SVF, STAPL, TDS, COC and TBC.
Such packages are comprehensive development environments offering a powerful ATPG tool suite, universal ISP tools, a fully automatic Flash program generator (AFPG), an interactive debugger and many other benefits.
The LAN 1149.1 is compatible with Goepel's extensive family of boundary scan controllers operating on VXI, PXI, PCI, USB, PCMCIA, GPIB, parallel port and RS232 buses.
It has a 100BaseTX terminal, supports TCP/IP protocol and can be used for plug and play and hot insertion.
