FIC-4SAE/FIC-8SAE
Introduction
The 4-/8-port enhanced high-speed synchronous/asynchronous serial interface module
(FIC-4SAE/FIC-8SAE) transmits, receives, and processes data on the synchronous/asynchronous
serial interface. They support both synchronous and asynchronous modes. In synchronous mode,
they support the DTE/DCE mode.
DTE and DCE
An FIC-SA module is typically connected to an external modem for dialing purpose, and an
appropriate baud rate setting is required.
The synchronous serial interface can work in either DTE or DCE mode. Two directly connected
devices must work as DTE and DCE. The DCE provides clock synchronization and specifies the
communication rate, whereas the DTE accepts clock synchronization and communicates at the
specified rate.
The router typically works as a DTE. To identify whether the equipment connected to the router is
DTE or DCE, refer to the manual shipped with the equipment.
Speed and transmission segment of synchronous/asynchronous serial interface
In different operating modes, the synchronous/asynchronous serial interface supports different
electric signal specifications and baud rates. In addition, the maximum signal transmission segment
depends not only on the specified baud rate but also on the selected cable. The following table
shows how the cable type, baud rate, and the maximum signal transmission segment related to each
other.
