Standard DC Power Connection
Connection of the DC supply should be performed according to the diagram shown above. It is important that
the N+ module power be 12VDC supplied from an independent battery backed power supply unit such as the
PRT-PSU-DIN capable of supplying the required voltage.
Warning:
The 12V N+ and N- DC power input must be supplied from only ONE point. Connections from
more than one 12V supply may cause failure or damage to the PostX module.
The 330 Ohm EOL (End of Line) resistor provided in the accessory bag MUST be inserted
between the NA and NB terminals of the ACC-485 module directly connected to the PostX
module..
