RS-232 Insertion
A user can connect a control system to the PowerCage 401 to send and receive RS-232
data over the fiber or the captive screw port of the installed transmitter and receiver cards.
The frame has two UARTs per slot and when a dual transmitter or receiver module is
installed, the RS-232 signal from each UART is routed to one of the fiber or captive screw
ports on the card.
The RS-232 insertion can operate in three modes:
•
Captive screw insertion
•
Ethernet to fiber insertion
•
Ethernet to Captive Screw Insertion
All three modes can be configured via PCS in each transmitter or receiver. Following are
three demonstrations of each mode of operation.
Captive Screw Insertion (Default)
A user can connect an RS-232 signal from a control system to an endpoint and pass that
signal over the fiber to the connected endpoint. An RS-232 signal must be inserted in the
RS-232 port on the transmitter or receiver card and bidirectional fiber must be used. The
RS-232 signal settings are:
Baud rate:
9600
to
115000
(Default =
9600
)
Data bits:
5
to
8
(Default =
8
)
Stop bits:
1
to
2
(Default =
1
)
Parity:
O
dd,
E
ven, or
N
one (Default =
N
one)
The RS-232 insertion method on both endpoints passing the control signal must be set
to Captive Screw Insertion via PCS (see the
PowerCage 401 Series Help File
for more
information).
Bidirectional fiber system
When the endpoints are setup as a bidirectional fiber system, the control insertion can
function bidirectionally.
