PC keyboard port with an RS-232 or RS-485 serial interface, while retaining use of the keyboard. Supporting data rates up to 9600 bps, the Patton Model 2003 has a myriad of applications: simulate keystrokes for software testing, use one RS-485 host to simul- taneously control the testing of up to 54 (RS-485) target systems, mon- itor keyboard activity (Monitor Mode), “add”...
These externally accessible switches op a sequence of keystrokes and send them to the keyboard port located on the front of the Model 2003 as shown in Figure 3, below. of a computer running the software that you want to test. You can do this without having to add any software or ports to the comput- er system you are testing.

The diagrams below show pin connections between the Model 2003's RS-485 half-duplex serial interface and a typical RS-485 serial The Model 2003’s main job is to accept data from the RS-232 or interfaces. You may use these diagrams to construct your own cables, RS-485 port and send it through to another computer's keyboard port.
For an ASCII transfer, each pair ASCII encoded characters is interpreted as a keyboard Rule #7. If line turn around is set or if the Model 2003 is code. For a binary transfer, each 8 bit character is interpreted addressed, a colon is sent back acknowledging the data sent.
