FYI - the documentation that comes with the Accton Acc-10 is incorrect in one small point. On page 3 it shows that the SQE function is disabled by default. This is true, but the jumper setting for the disabled state is shown in Figure 3-1 to have the pins on J1 unjumpered when in actuality, SQE is turned off by jumpering the pins on J1 (which is the way the unit ships). We discovered this when we tried connecting a DEC 100 Communications server with this guy. It didn't work so we tried a David Systems transceiver (with SQE on) and it *did* work. We then tried the same David transceiver with SQE off and it didn't work (unlike the Accton, the David transceiver has an SQE LED so its apparant when SQE is on or off). So, after unjumpering the pins on J1 of the Accton (turning SQE on) the DEC 100 is humming right along. This is actually the first instance of *anything* I've ever hooked up really caring whether SQE was on or off which leads me to believe that most software would go on transmitting even though the collision detect circuitry in the transceiver had died.
