TESS Emulation
6.5 TESS Emulation
TESS (T eklogix Screen Subsystem) is the normal operating mode of Psion Teklogix
computers. T eklogix protocol emulation softw are resident on network controllers or
a Psion Teklogix Software Development Kit (SDK) and installed in the host
converts host screens to TESS commands. The 9150 Access Point is also equipped
with protocol emulation software.
Note: If the message “RESET: Press Enter” flashes at the bottom of the TESS
screen when you turn on the 7530, press the <ENTER> key once.
6.5.1 Configuration
Note: Each TESS session must have a unique name assigned to it. The title
you assign will be displayed in the Display Menu.
The process of renaming an existing TESS session and adding a new session is
described in the section titled, “Applications” on page 194.
A unique number must be assigned in the “T erminal #” parameter for each TESS
session. Refer to “T erminal #” in the section titled “TESS Settings” on page 212
for details.
6.5.2 Working With Multiple Sessions
To display another session in TESS:
• Go to the startup ‘Display Menu’. If you are in a TESS session, press
<CTRL><ALT><0> to go to the ‘Display Menu’.
• Type the letter corresponding to the application you want to launch.
For example, suppose the sessions are listed in the “Display Menu” as
‘D TESS1’ and ‘E TESS2’. To launch the session named TESS2, type
the letter e.
6.5.3 The Field Types
Fixed Field – displays information that cannot be changed from the keyboard.
Entry Field – allows the operator to enter data. This type of field is usually sho wn
as: “........”
Match Field – the host computer loads data in the format of the expected entry. If
the entered data does not match the expected format, the unit emits a long beep.

Lock Messages
6.5.7 Lock Messages
When information is transmitted to the host computer, the ke yboard locks to
prevent further data entry until the 7530 receives a reply. A locked state is
indicated by either “LOCK-B” (base) or “LOCK-H” (host) in the lower left
corner of the display .
When the reply is received by the 7530, the lock message disappears and the
keyboard can be used again.
6.5.8 Control Commands
A group of <CTRL> key commands can be used within TESS to dictate ho w the
7530 will operate under a variety of conditions.
• <CTRL> <P> – Reprints the last print page sent from the host. This key
combination will not print anything if a print page from the host was not
previously received at the 7530 hand-held.
• <CTRL> <S> – Displays the 7530 status continuously. Below is a sample
status line as it might appear at the bottom of your screen:

The Local Menu
6.5.10 The Local Menu
The host can store local procedures in the 7530 for use when the unit is off-line.
A menu of these procedures appears whenever <CTRL> <L> is pressed
(see Figure 6.3).
• Press the function key corresponding to the procedure you want to perform.
Local procedures will not function when the “Lcl Process” and “Queuing”
parameters are disabled (see “Lcl Process – Save on Reset” on page 219
and “Queuing” on page 219).
Although using local procedures eliminates the advantages of an on-line 7530,
it allows work to continue when the host is unavailable. The “LOCK-B/H”
messages are replaced with “NEXT-B/H” in this mode.

Chapter 6: Tekterm Application
Queuing Mode
6.5.12 Queuing Mode
In some applications, queuing mode can decrease the computer lock time. In queuing
mode, the host computer may send several pages to a 7530 without waiting for
a response. These pages are stored in a queue within the 7530 hand-held. The
operator completes the entries on the first page and then, presses a function key.
The 7530 simultaneously transmits to the host and displays the next page in the
queue. The computer does not lock, allowing the operator to enter data on the next
page immediately . This continues as long as there are pages in the queue.
Queuing mode is used for repetitive tasks, and the queued screens look identical.
The 7530 displays a “Next” message indicating that a new page is on the display.
“Next” messages also contain information about radio communications: “NEXT-B”
indicates that the 7530 has data to transmit to the base station. “NEXT-H”
indicates that the base station has acknowledged a transmission. Unlike lock
messages, “Next” messages do not lock the keyboard. K e ying is allowed while
“Next” messages are displayed.
While queuing mode may improve apparent response time, it can present difficulties
to hosts that are operating in real time. It should only be used after careful
consideration of the host environment. The 7530 must be configured for queuing
mode (see the “Queuing” parameter on page 219). Additional information on
queuing can be found in the TESS (Teklogix Screen Subsystem) Manual.
6.6 ANSI Emulation
The Psion Teklogix 7530 in ANSI mode operates like most other ANSI terminals.
This means software that supports ANSI terminals requires little or no changes.
6.6.1 Configuration
To configure the 7530 for ANSI mode, the “Name” and “Type” of session – in this
case, ANSI – must be specified in the Applications menu. This menu is described in
the section titled, “Applications” on page 194.
Next, a unique number must be assigned using the “Terminal #” parameter. This
number should be unique across the entire system – that is, each 7530 and each
application session in each 7530 across your system must have a unique number
assigned. This parameter is described in the section titled “ANSI Settings” on
page 195.
Once the 7530 is configured, an ANSI operation can be selected from the startup
“Display Menu”.

Chapter 6: Tekterm Application
Sending Data To The Host
6.6.2 Sending Data To The Host
7530 hand-helds running ANSI sessions transmit characters to the host as soon as
they are typed. The 7530 provides parameters that determine when the computer
transmits characters to the host.
The 7530 can be configured to transmit after a number of characters are typed
in (the “Xmit Count” parameter) or after some time has elapsed (the “Xmit Wait”
parameter), or both. This reduces overhead on the radio link and impro v es response
time. See page 202 for more information about these parameters.
You can also determine whether the 7530 transmits immediately after the
<ENTER> key, an arrow key, or a function key is pressed.
The 7530 computer also responds immediately to the device attribute requests
“CSIc”, “CSI0c” and “ESCZ”.
Note: For a more detailed description of the parameter settings for ANSI,
refer to “ANSI Settings” on page 195.

802.IQ v1
When 802.IQ v1 is set to “Y”, the attached sub-menu of parameters is enabled.
Auto Radio Addr
If this parameter is enabled (set to “Y”), a request is sent to the network controller to
assign a radio address to the hand-held computer radio.
If “Auto Radio Addr” is set to “N”, the value entered in the “Radio Address”
parameter is used. (Refer to "Radio Address" in this section for details about
manually assigned radio addresses.)
Important: Ensure that all 7535s grouped in the system use the same
addressing process – that is, if you choose to use automatic
radio addressing, use this addressing process for all units
operating in the same system. If you choose to assign radio
addresses manually using the “Radio Address” parameter, use
this process for all units in the same system.

System Parameters
Radio Address
The value entered in the “Radio address” parameter is used to identify the
7535 over the radio link. A unique value from 1 to 3840 must be assigned
for each 7535 hand-held computer.
Initial RTT (Round Trip Time)
Round trip time is the elapsed time between a hand-held computer transmission and
an access point acknowledgement. Each 7535 continuously adjusts the acceptable
round trip time, calculating the average elapsed time ov er a number of transmissions. If an acknowledgement takes longer to receive than the average round trip
time calculated, the computer will resend the transmission.
Because 7535s cannot calculate an average round trip time without a number of
transmissions, a starting point or “Initial Round Trip Time” is required. The computer uses the time assigned to the “Initial RTT” parameter as a starting value for
round trip calculations. Once the 7535 begins transmitting and receiving data, this
value will be adjusted to reflect the actual average round trip time between transmissions and acknowledgements.
Protocol Type
“Protocol Type” is used to identify the Ethernet packet frame type sent by the 7535.
The default value –
protocol Ethernet packet frame types.
2457 – assigned to this parameter identifies the T eklogix 802.IQ
The “Protocol Type ID” should only be altered if the default value is already being
used to specify another application Ethernet frame type.
Important: If you change the value assigned to “Protocol Type ID”, ensure
that all 7535s and 9150s in your system use the same number.
