Port
Baud Rate
The port entered must be the serial port connected to the NCM either
directly or via a modem. (See Establishing a Connection later in this
section.) The allowable serial ports and their configuration defaults are
shown in the table below. If you do not specify a port, the NT Emulation
software will communicate via COM2.

Table 6: PC Serial Port Configuration Defaults
The baud_rate specified must match the baud rate defined for the NT
port at the Network Control Module (NCM). Standard value is
9600 baud; however, if you are using a PC with a 8086 processor or a
286 processor running at less than 14 MHz, and you are using a mouse
that is interrupt driven, you need to lower the baud rate to 2400 for
optimum efficiency. The NT Emulator supports baud rates of 300, 1200,
2400, 4800, and 9600. For instructions on changing the baud rate
defined for the NT port, see Defining Devices in your Operator
Workstation User's Manual, and the Reference section of your DDL
Programmer's Manual.
Note: If you do not own these manuals, contact your local Johnson
Controls office for help.
