Terminal Server Ports (DTE Interface)
(Interface “C” in
Figure 2-1
)
The Terminal Server port is a DB-25 connector located on the shelf rear panel at the SC-IP slot (J1-
J16). It supports 2400, 4800, 9600, 19200, 38400 and 57500 bps asynchronous data for terminal
interface control of up to eight attached devices. An interface cable, harmonica adapter and cable/
adapter suited to the intended terminal devices will be required. The table below describes the
Terminal Server port pinouts.
Note
In order to establish a Craft session via the SC-IP’s Terminal Server port, some devices will require control
leads tied to the appropriate state. For example, a device with a 25-pin terminal connection may need one or
more pins driven to the EIA high state.
