NECA 340-414-300 Revision 2.0 Page 1 of 6 MCU 5000A Multipoint Control Unit INT-001 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 5000A, as well as a control terminal for the multipoint teleconference and/or the NEC’s VIDEO CODEC of VisuaLink 5000A terminal. The MCU console can also be connected to the MCU 5000A via modems for remote control. 1.03 The reference practices are listed below: 1)NECA 340-414-100 ………… General Description 2)NECA 340-414-210 ………… Installation 3)NECA 340-414-220 ………… System Parameter 4)NECA 340-414-300 ………… Console Operation 5)NECA 340-414-500 ………… Maintenance

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.

NECA 340-414-300 Revision 2.0 Page 3 of 6 MCU 5000A Multipoint Control Unit INT-001 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. Figure 2: Reverse Cable Connection 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 Bits : 8 bits • Stop Bit : 1 bit • Parity Check Bit : None • X Control Bit : None FG (1) SG (7) SD (2) RD (3) RS (4) CS (5) CD (8) ER (20) DR (6)FG (1) SG (7) SD (2) RD (3) RS (4) CS (5) CD (8) ER (20) DR (6) TO MCU 5000A (DTE)TO MCU CONSOLE (DTE)
