Connect the DATA pair from the network to pins 3 and 6 of the RJ45 wall jack maintaining polarity of the pair.
If a remote power source is being used, the negative side of the supply must be referenced to Earth Ground, as
well as, the CB901 power supply.
J2 - 9 pin (DB9) RS232 signals :
The DNA100 has a RS232 serial port interface, J2, that can connect to a terminal or printer. Check your
terminal, printer or video switcher manual for the correct RS232 connector type, input, output and handshaking
signal connections.
The maximum length for a RS232 cable connecting the DNA100 and other equipment is 50 feet.
A null-modem (LapLink) cable can be used to connect a DNA100 and a laptop or computer together if they are
close enough to each other.
