Introduction SE4000 MPEG-2 Contribution Encoder
2-8 01-0934-401-B
If the internal clock is used to latch the data, the length of cable between
the DTE and the SE4000 must be limited to one meter (3 feet).
Additionally, the auxiliary data rate must be limited to not more than
64 Kbps. If the cable length exceeds one meter, or if it is attempted to
process data at rates above 64 Kbps, the auxiliary data may be corrupted.
2.5.3 Asynchronous Configuration
In asynchronous configurations, ports are configured to accept RS-232 input at rates of 1200 bps
to 115000 bps.
2.5.3.1 RS-232
The DB -9 connector allows a standard RS -232 DCE connection. The auxiliary data asynchronous
port pin assignments for RS-232 are listed in the following table:
Aux Data Port Pin Assignments: Asynchronous - RS -232
Pins Signal Direction Definition
1 Unused - -
2 Unused - -
3 TD In Transmit Data
4 Unused - -
5 GND - Ground
6 Unused - -
7 RTS In Ready to Send
8 CTS Out Clear to Send
9 Unused - -
2.6 Remote Control Ports
A remote unit can be connected through either of two ports located on the SE4000:
•
RS-232
•
Ethernet Control
2.6.1 RS-232 Control Port
The RS -232 port is a DB-9 female connector. The port is configured as a DTE
