1.Change
EDP has introduced the Telxon ptc-910 hand
held data capture unit. The ptc-910 is a battery powered
handheld portable transaction computer (ptc)
used to collect, store and transmit data. It has an alpha
numeric keyboard, a 4 line LCD display, and a
built in bar code scanner; either a laser or led version.
It's main application will probably be in
warehouses or retail environments, for stock checking and control,
and is designed to be used with merchant.
The EDP application programme has to be preloaded.
The data that can be collected by the ptc-910 consists of:-
Identity of user
Location
Identity of stock item (either via keypad or bar code reader)
Quantity either + or -
This data is stored on the ptc-910 and then
can be uploaded to a host system, using the unique cradle
described below.
2.cradle
The cradle, the sc-910, provides a safe
storage position for the ptc-910l, and can charge the battery
pack fitted to the ptc-910, and also charge an
extra battery pack. The cradle also provides the opto
coupling for the interface between the ptc-910
and the host computer system. Cradles may be physically
daisy chained together to house multiple
installations. They may also be wall mounted. Cradles are
powered by an external power supply.

3.warning
The laser version, the ptc-910l, is a class
ii laser. Do not stare into the beam, especially if the protective
cover is removed. Observe the warnings on the
labels. The laser version has a longer 'barcode to reader'
range.

7.warning
The ptc-910 has a 9 pin d-type connector
fitted to it. This is not to be used for connection to a pick
system, as disconnecting a cable would then
leave that cable unterminated.
8.batteries
The batteries initially require charging for
approx 12 to 14 hours. For a low battery condition, the ptc-910
alerts you by beeping three times and
displaying a low battery warning. Battery life 8-10 hours approx.
There is an internal battery back up which
will protect the data stored in the memory, when the battery
pack is removed. This will last for approx 20
mins.
Ensure that ptc-910 is switched off, before removing or replacing the battery pack.
If the battery has been stored in a very hot
or very cold environment, allow it to reach room temperature
before charging.
9.keypad
9.1the keypad consists of 28 character and 8 control keys. As there is a full
upper/lower case alphanumeric
capability, including all punctuation
characters, as well as CTRL+ and ALT+ ; this means that the input of
one character may involve several sequential
kay presses.

10complete commissioning & installation
10.1preprogramme the ptc-910 to the customers requirements called pre-installation see
para 11. Carried out
off Site.
10.2test off site. See para 13.
10.3install on site and test see paras 12 & 13.
11.pre installation
11.1.requirements
* ptc-910
* cable pc com1 to ptc910 as detailed in para 14.3.
* pc with customers customised software on the hard disk or floppy disk.
11.2.the ptc-910 must be custom pre-programmed to the pre-determined standards for each
individual customer
before it is sent for installation on site.
11.3the ptc-910 can have its memory split, in up to 4 drives, a, b, c and d.
To load the edp standard application requires:-
Clearing the d drive to reset the unit.
Partitioning the ram into ramdrive and program memory;
So drive a becomes drive b
And drive b becomes drive c.
Flashing the unit to reload the program files
Loading the application.
11.4.use the keypad sequences listed in para 9 to give the required characters.
11.5.to clear previous d: drive (optional)
This is only done if the unit already has a
c: drive. The purpose of the command is to reset the unit back
to it's original state.
Enter c: \edisk 2
11.6.to partition the ram into ramdrive and program memory.
The result of this command is that drive a: becomes drive b: and drive b: becomes drive c:
The command will vary depending on the memory of the unit as follows:
1 mb units type:b: \edisk 0 432
640k units type:b: \edisk 0 384
512k units type:b: \edisk 0 160
(if the size is unknown, start with the largest. If it is incorrect the display will tell you, try the next size.
11.7.flashing the units reloads the programs and files required to use the ptc units.
Connect the ptc unit to the pc using the cable listed in para 14.3.
On the ptc unit navigate to the c: drive and enter 'flashr'.
Select the 'o' option and 'y' to accept.
On the pc navigate to the directory where to
ptc files are located and type 'flashpc'. Enter the arc
filename 'chip_arc.h86', press enter at the 'rf
arc' prompt and select '1' from the menu to send the arc file.
After completion choose the 'o' option to exit.
11.8.to load the application 'ptcdemo.exe' as 'app.exe' on the ptc unit.
The ptc unit must still be attached to the pc to do this.
Navigate to the b: drive on the ptc unit and type 'txrx'.
Choose the following options:
Receive file
38400 baud
File name: app.exe. Do not press enter yet.
On the PC navigate to the directory
containing the PTC files and type 'TXRX'. Choose the following
options:
Send file
38400 baud
File name: ptcdemo.exe
Press enter on the ptc-910 then press enter on pc.
Note: this may not always work the first
time. You may have to end/escape from this process and retry. Do
not escape all the way out of this process, but
re-enter the receive and send options along with the
correct file names. It usually works the second
time.
Test the application 'app.exe' on the ptc unit by following the instructions provided in para 13.
12.installation
12.1.ensure all items are switched off.
12.2.connect the cradle (sc-910) to it's charger unit.
12.3.connect the cradle (sc-910), host port connector to the host computer system using
cable type h for rtc
and cable type fa for digiboard.
If it is a multiple installation site,
connect further sc-910's to the daisy chain port. If this is the second or
subsequent unit, connect the host port to
previous daisy chain ports.
12.4.connect battery pack to the ptc-910.
12.5.insert the ptc-910 into the sc-910.
12.6.power on the sc-910 charger unit.
Ensure the power and term batt lamps are lit.
12.7.power on the host computer system, RTC or DIGIBOARD and test as per para 13.
13.testing
13.1to begin the ptc application navigate to the a: drive
And type the application name, i.e. app and enter.
Follow the instructions and prompts.
The ptc menu is as follows:
0 - exit
1 - pick (capture barcode data)
2 upload (transfer captured data to main machine)
13.2data capture
Select option 1 - pick
The pick routine is as follows:
Header information
Name: this is the person counting the stock.
Location: this refers to the location of the stock.
Detail stock information
Bar code: scan, or key in, the barcode number.
Quantity: key the quantity of above stock counted.
Note: negative numbers should be entered with
A zero in front to identify the number
As being negative. E.g. 010 = -10
When a duplicate barcode is entered a loud beep will be
Made and the prompt 'include y/n' allows the operator to
Either include the entry and continue or to ignore.
(y) allows the operator to include and enter a quantity.
(n) allows the operator to ignore and enter another code.
13.3upload ptc910
The ptc910 should be in the cradle, with the power on
And the unit switched on.
The upload routine is as follows:
Prepare the system to receive the data - see para 13.4 or 13.5.
Select option 2 - upload
The ptc prompts the operator 'send to pc y/n'.
If the operator enters 'y' the unit will
then display 'sending' number of records. See also 13.4 and 13.5.
Once all records have been transmitted the user
is asked if they wish to erase the data from the unit. If
the transmission has not been successful the
data should not be erased.
If no records exits to send the unit will beep and inform the user that no records exist.
13.4.upload pick system - non customer site for edp test only
Instructions to use the 'ci-dtp' protocol.
Ensure line protocol is set to 9600 baud, odd, 8 bits.
On a machine, log to merchant.
At 'tcl' type the following command:
Ci-dtp filename itemname (portnumber,mode
Where:
Filename:a valid pick file
Itemname:a nonexistant new identifier
Portnumber:the port connected to the ptc unit
Mode:must be either r(eceive) or s(end)
For example
>ci-dtp work.file 1 (024,r
Note:the ptc unit must be 'sending' and
connected to the machine before the above command is
executed, as per para 13.3.
Source for the above protocol should be in the 'mer' account 'bp' file.
13.5.upload pick system - customer site
