6.3 Serial Port Hardware Description
The three RS-232 ports are used to connect to a PC, GOES Transmitter, modem, remote display,
or other serial equipment for standard serial communications. These ports are configured as a
DTE type of device. This means they will plug directly into a modem (a DCE type device), but
will require a NULL modem adaptor if connected to a PC (a DTE type device). The NULL
modem cable crosses the communication lines allowing two similar devices to communicate.
Figure 2-5 shows the pin out for all three ports.
