Model 1981 POR T EXP ANDER This manual describes the installation procedures for the American Dynamics model 1981 Port Expander. The 1981 Port Expander is used to increase the number of RS-232 I/O ports on the 1650, 1995, 1996, and 2150 Systems. The Port Expander uses one I/O port to accept an input and then expands that one input to four outputs.

DESCRIPTION The 1981 Port Expander is used to increase the number of RS-232 ports on the 1650, 1995, 1996, and 2150 Matrix Switching System CPUs. The Port Expander uses one CPU RS-232 port and expands that to four ports. These ports are for use with external RS-232 devices, such as keyboards.
SETUP Port Baud Rates As shipped all 1981 Port Expander units are configured as follows: Input Baud Rate - 1200 (Keyboard ports) Output Baud Rate - 4800 (System port) See Figure 2 below to locate the baud rate jumper pins on the main circuit board of the 1981.
CONNECTIONS Connections between the 1981 Port Expander and the 1650, 1995, 1996, and 2150 System CPUs, and between the 1981 and the keyboard(s) are discussed in the following pages and illustrated in the Appendix.
1981 to 1995 Connections The 1995 System has ten RS-232 ports. With the use of 1981 Port Expanders, you may expand the number of ports on the 1995 CPU to a maximum of forty. This type of connection is illustrated in Appendices B and C. The 1981 has five RS-232 ports.
1981 to 1996 Connections The 1996 has ten RS-232 ports. With the use of 1981 Port Expanders, the number of input keyboards that can communicate with the 1996 can expand to a maximum of forty. This type of connection is illustrated in Appendix D. The 1981 has five RS-232 ports.
1981 to 2150 Connections The 2150 has three RS-232 ports. When the 1981 Port Expander is used with the 2150, the number of inputs (keyboards) that can communicate with the 2150 can expand to a maximum of twelve. This type of connection is illustrated in Appendix E.
CONNECTIONS 1981 Connections for 2010DBVL Video Loss Detector Data Buffer Modules The 2010DBVL Video Loss Detector modules of the 2050 Switching Bays must communicate with only a single port on the 1996 CPU.
