Serial Port

You can connect the GX Series device's 9-pin serial connector directly to most
computers or other devices with a standard straight-through cable. This connector
is used for device configuration and debugging.
This connector complies with the EIA RS-232D specification for DCE equipment.
The output driver levels swing from -7 VDC to +7 VDC with normal loading.
Note: If you have a DCE device, you need to use a null modem cable.
