INTRODUCTION
1:  GENERAL 1.01
This introduction describes the interface between the Multipoint Control 
Unit 5000A (MCU 5000A)
 and the MCU console, the starting-up of the MCU 
5000A and the MCU console, and data transmit format.   
1.02
The MCU 5000A has four serial interface ports, and  three of which are 
used to connect the MCU consoles.   The MCU console is used for the initial 
setting and maintenance of the MCU...

2:  INTERFACE A.  Physical Interface
2.01
The serial interface ports on the MCU 5000A and the MCU console are 
RS-232C D-sub 25-pin connectors.  The MCU 5000A can accept three consoles, 
MCU ports.
B.  Electrical Interface
2.02
The pin assignment for an RS-232C D-sub 25-pin connector on the MCU 
5000A and the MCU console is shown in the Table 1, and the pin arrangement is 
shown in Fig. 1.

2.03
The MCU console is connected to the MCU 5000A via a reverse cable 
connection (null modem).  A modem can connect via a straight cable connection.  
The reverse cable connection is shown in Fig. 2.

2.04
The communications requirements for the RS-232C interface of the MCU 
console are as follows:
• Synchronization : Start/Stop
• Baud Rate : 1200, 2400, 4800, 9600 b/s
• Character...
