This chapter contains information and procedures to allow you to perform the
various types of data transfers required to:
• Develop applications for the Omni 37xx terminal.
• Prepare Omni 37xx terminals for deployment.
• Maintain Omni 37xx terminal installations in the field.
• Transfer data to/from terminals.
In this chapter, information pertaining to file authentication is only discussed in the
context of procedures while performing file downloads. See Chapter 5 for further

Download
Methods
The following four methods are available for file and data downloads through the
Omni 37xx download and upload procedures:
• Direct downloads: Files and/or data transfer directly from the sending system
(a host computer) to the receiving system (an Omni 37xx terminal). A special
cable (VPN 05651-xx) connects the RS232 serial ports of the two systems.
• Downloads by telephone: Files and data transfer over a telephone line from
the sending system (a host computer) to the receiving system (an Omni 37xx
terminal). The modem of the sending host computer, and the internal modem
of the sending receiving terminal are connected by a telephone line
connection. Data transfers into the Omni 37xx terminal through the
communication port contacts.
