Purpose of This Guide
This programmer’ s reference guide describes INTERMEC
R
radio products using Systems Network Architecture and
Synchronous Data Link Control (SNA/SDLC). The radio
products emulate IBM products that communicate using
the 5250 data stream.
The 5250 data stream governs the data flow between the
host computer and wireless terminal emulation stations. It
specifies what data can be displayed on the wireless station
and how it must be positioned. It also defines the types of
data a wireless station can collect for each input field.
The purpose of this guide is to define the differences
between IBM’s implementation of the data stream and
adaptation of the 5250 data stream for hand-held wireless
stations.
This guide contains descriptions of:
" How the wireless stations’ keyboards and overlays
emulate the IBM 5291 Display Station
" 5250 display data stream commands and orders sup-
ported by the wireless stations
" Extended commands for the wireless stations
" Line configurations for IBM host computers
5250 Terminal Emulation Programmer’s Reference Guide 1-1
SECTION 1 " Introduction
Two types of 5250 products are available: those for an IBM
midrange host computer (such as System/36, System/38,
and AS/400) and those for personal computers serving as
host. This programmer’ s guide describes products for IBM
midrange host computers.
Intended Audience
This guide is prepared assuming you are already familiar
with the operation of the 5250 data stream and equipment.
The intended audience is the host computer programmer
who needs to design interfaces to wireless stations set up
for 5250 terminal emulation.
What to Read First
Before you begin using the wireless station as an emulation
product, read the sections about the wireless stations you
are designing interfaces to. The information will give you a
basic understanding of the equipment you will be working
with. You can also skim the appropriate data stream commands for programming guidance on the 5250 commands
the wireless stations support.
If your wireless station network has not yet been installed,
read first the installation and user guides provided with
your hardware. The guide describes how to install the
hardware and configure it according to the requirements of
your site.

Radio Network Description
A radio network using the 5250 data stream corresponds
directly to an IBM 5250 hard-wired network. A controller
emulates an IBM 5294 or 5394 Control Unit. Wireless stations emulate IBM 5291 Display Stations. The radio link
between a base radio and a wireless station replaces the
coax link between a control unit and display station. Programs are written for the wireless stations exactly as they
would be written for a 5291 Display Station, with the exception of screen size and specific extensions. Nomenclature
for commands, orders, and functions are the same where
possible.
The following pages briefly describe the components on the
radio network. For more information about each component, refer to its user guide.
SECTION 1 " Introduction
Host Computer
The radio network operates with an IBM AS/400, System/36, or System/38 host computer as a central distribution point for commands and data storage. Commands originate in the application program on the host computer .
The 5250 host communicates in strings of EBCDIC characters. The sequence of events that make up the communication cycle is the same for any protocol, data stream, or system of transmission:
1. The host computer’s operating system makes a connection with the controller , or vice versa.
2. Each wireless station starts a session with the host
computer’ s operating system.
3. The wireless station selects the host connection and
application.
4. The application communicates with the wireless station.
5250 Terminal Emulation Programmer’s Reference Guide 1-7
SECTION 1 " Introduction
Controller operation in use is transparent to the host.
The host computer’ s application program serves as a con-
duit to the controller . The controller, in turn, serves as a
distribution point for the radio network. When a wireless
station logs onto the system, the controller activates the
host program. Based on data from the host computer , the
controller program then controls the screens sent to the
wireless station and uses the wireless station’s responses to
access or update the host computer’ s database.
Controller
The controller is the “gateway” that passes messages
between a host computer and the wireless stations. The
controller links the host computer to a base radio, which
communicates with the portable wireless stations on the
wireless network. The wired and wireless network is transparent to the host computer , which sees the wireless network as a set of desktop terminals.
The controller establishes a communication session with
each wireless station to exchange digital information.
While the wireless station’s application program handles
the individual wireless stations, the controller makes the
complement of wireless stations look like a hard-wired network to the host computer operator .
Controllers can emulate four multidrop IBM 5394 or eight
5294 Control Units. The primary consideration governing
the configuration is which IBM host is in use:
" Emulation of 5394 Control Units works best for IBM
AS/400 host computers.
" Emulation of 5294 Control Units works best for IBM
System/36 and System/38 host computers.
1-8 5250 Terminal Emulation Programmer’s Reference Guide
SECTION 1 " Introduction
The controller supports 64 logical units (LUs) which correspond with wireless station network addresses 0 to 63.
When emulating four 5394 Control Units, each logical controller handles 16 LUs. A group of 16 LUs is linked to each
SDLC address, numbers 1 through 4. Figure 1-1 shows a
logical representation of four 5394 Control Units emulated
by the controller .

In either emulation, SDLC addresses can range from 1 to
254. Each SDLC address must be unique.
In either emulation, you can eliminate unused PUs by
reducing, through the controller’ s setup parameters, the
number of LUs supported. Refer to the controller’ s user
guide for more information about setting up the controller .
1-10 5250 Terminal Emulation Programmer’s Reference Guide
SECTION 1 " Introduction
Base Radios
Base radios (also called access points) directly connect to
the network and pass information from the wireless stations to the controller . Wireless stations passing from the
coverage area of one base radio to another are tracked automatically by the network. This is called “roaming.”
Multiple base radios can be hard-wired to an RS-485 or
Ethernet backbone, or linked through a radio connection
between base radios. One base radio must be hard-wired to
the controller .
The controller communicates with the base radios over a
wired network. Messages to the wireless stations from the
controller are passed over the wired network to the base radio. The base radio converts the message into the protocol
used by the wireless station, and distributes the message
onto the network. The wireless station receives the message over the radio link. The process of formatting and
handling the messages between base radios and the wireless stations is transparent to the operator .
Base radios operate within the 900 MHz or at 2.4 GHz
(WLIF) frequency range. UHF base radios operate in the
450 to 470 MHz band of radio waves.
Wireless Stations
The wireless stations are the portable components on the
network. Their small size allows them to be used in the
warehouse or plant to gather information through the keyboard or integrated bar code scanner . The portable wireless
stations provide interactive communication between the operator and host computer .
5250 Terminal Emulation Programmer’s Reference Guide 1-11
SECTION 1 " Introduction
Wireless stations provide portable, wireless interactive data
communication and support bar code scanning for real-time
data collection. They are the network-addressable software
entity which interfaces the wireless data network to the
base radio.
Each wireless station monitors all messages from the host
computer and responds only to those containing its unique
address number . This communication process allows commands and data to be received, stored, and processed. Data
collected by the wireless station’s keyboard or scanner is
returned in a similar fashion. The controller buffers (saves)
the data to be forwarded to the host computer .
The information in this programmer’ s guide applies to all
wireless stations set up for 5250 terminal emulation. Wireless stations have UHF, 900 MHz, or WLIF radios.
