EXTERNAL DEVICES

External devices can be connected either with a direct serial connection or with an Internet Protocol connection. An overview of each type of connection is provided below; refer to the specific instructions provided for each type of external device in the following pages.

Direct Serial Connection

A direct serial connection means connecting the device to one of the COM ports on the VMX300(-E) rear panel. If your system contains more than one VMX300(-E) workstation, be sure to connect the device to the workstation that the device driver runs on.

The VMX300(-E) provides the following types of COM ports:

RS-232:COM 1, COM 2

RS-422:COM 3, COM 4

After installing system hardware, ensure that the device’s internal settings match the VMX300(-E) COM port serial communication settings. If they do not match, you must either

configure the internal settings to match the VMX300(-E) COM port default settings, as identified in Table F, or

change the VMX300(-E) COM port settings to match the device; instructions are provided in the Appendix on page 42.
