5.2 POWER-UP
Apply AC power to the Model 1226 by plugging the separate AC
power adapter into the rear panel outlet of the Model 1226, and then
into an acceptable AC power outlet. Make sure you connect the parallel
side first, then the line side. There is no power switch on the Model
1226; when the “Power” LED is lit, the Model 1226 is powered up.
When the local and remote Model 1226s are both powered up and
passing data normally, the following LED conditions will exist:
●
PWR = Green
●
TD & RD = Red or blinking red/green
●
CTL IN & CTL OUT = Green
●
Status = Blinking green
