PESA controller. The Serial Port Expander can accept input from any number of serial ports. These ports can be configured as either RS-232 or RS-422 ports. In addition, it can accept input from TCP/IP connections. The software supports multiple connections to a single TCP/IP port. -
Page 8: Limitations
This product works only with the CPU Link Protocol No. 1. It does not work with any of the expanded or asynchronous PESA protocols. It does not work with many of the extensions to Protocol No.1 that are supported by the 3300/3500/3500Plus controllers. Applications such as Win3300, Win3500 or Win3500Plus will not operate if connected through the serial port expander. -

Page 21: Chapter 3 - Operation
There is a worst-case condition where a device could send a single byte of data to the Serial Port Expander and then fail. The Serial Port Expander would recognize that an input port had data and would grant exclusive access to the output port. -
Page 22: Software Configuration
Serial Port Expander Software Configuration The configuration file expander.conf is an ASCII text file which is used to configure the software. It specifies which ports are to be used as inputs and outputs, as well as the communication parameters of each port, such as baud rate, data bits, parity, etc. -
Page 23: Configuring For Multiple Output Ports
Serial Port Expander Configuring for Multiple Output Ports The default configuration supports only a single output port. However, it is possible to support two or more output ports by running two or more instances of the application. Doing so requires that two configuration files be prepared, and that each instance of the application be told which configuration to use. -

Serial Port Expander NOTE When this technique is used, serial ports and TCP/IP ports may not be shared among processes. For example, it is not possible to use COM6 as an input port in both processes. It is also not possible to use port 4000 as an input port in both processes. - Page 25 Once the editor has been started, it will be necessary to modify the contents of the file.

Serial Port Expander phase modulation that transmits four bits per baud. At these speeds, data transmission rates are usually expressed in bits per second (b/s) rather than baud. Baud was originally a unit of telegraph signaling speed, set at one Morse code dot per second. It was proposed at the International Telegraph Conference of 1927, and named after French Engineer J.M.E. -

Page 36: Figure 20. Input Offset, Single Routing Switcher
Serial Port Expander The coordinates of crosspoints in matrix space are determined by the strobe they reside on, and their input and output numbers. They are given in the form (input,output) on strobe x. The origin of a component (a matrix of crosspoints) is designated by the point that falls nearest the origin of its strobe (1,1). -
Page 37: Level
