TWINAXIAL OPERATION

When you attach devices such as the FormsPro 4000 series printer to the System 3X, the
devices must be configured onto the system by device type, so that they may be supported
and used to their utmost ability. Once a device has been configured onto the system, the
system utilizes the device type information to communicate with the device. The device
responds to the system's polls and commands in accordance to its device description. The
system being configured for a 4214 Model 01 printer, for example, as address 10 (port 1,
device 0) will expect a response from a 4214 Model 01 at that address location. Should there
be a 5256 Model 3 printer at device address 10 when the system sends a print job to the
printer, the system would generate a "HARDWARE FAILURE" error message (for System
38) or a "PROGRAM ERROR" error message (for Systems 34/36). It is very important to
observe the device and System 3X configurations.
The FormsPro 4000 series printers may emulate three different IBM models as listed in the
following table. The DIP switches allow you to select these emulations. As shipped from the
factory, the printer is set for 4214 Model 2 emulation.
