Serial Connections
Before you connect a device to a serial port, you need to know the following:
Type of device, data terminal equipment (DTE) or data communications equipment (DCE)
Type of connector, male or female, required to connect to the device
Signaling standard required by the device
These are the most common devices connected to the router serial ports:
Serial Devices
Devices such as RTU or
IED with serial
asynchronous interface
Note:
No synchronous
