1Network Installation
1.1 Installing the Network Memory Card
NOTE: New LP-IIs come with the Network Memory Card already installed. These instructions
can be used when replacing the card
1. Make sure that the Main Power switch is OFF & that the scale is unplugged.
2. Remove the keyboard:
A. Remove the 2 keyboard screws on top of the upper case.
B. Lay the keyboard face down.
3. Plug the Network Card into connectors J5 & J6 on the Main PCB. Make sure that all
of the pins are aligned properly and that the 2x9 connector is facing to the rear of
the scale.
4. Attach the 2 grounding screws to the Network Card PCB. Do not over tighten.
5. Reassemble in reverse order.
1.2 Network Considerations
The LP-2 uses a special high speed network called Ethernet. This allows you to connect up to
32 scales per installation site. The network is setup as a Master/Slave network that allows you to take
consolidated reports, transmit program data remotely, and manage up to 32 departments per site.
The network conduit configuration is star-topology. With a maximum speed of 4 Mbps and a max length
of 100 meters (325 feet), the LP-2 network can handle just about any application.
Please review the following when installing a network.
1. Check the overall network size and make sure that it falls within the limits.
2. Even though Ethernet cabling can be used, the use of Twisted pair Category-3,4,5
cable is preferred.
3. The network can run with a Master scale and no Mirror Master.
4. If you run into any trouble, please contact the CAS Service Department. We have
on-staff network specialists that can assist you if you run into any trouble or need to
exceed network specifications.

Any slave that is not in a sale mode will remain unlocked until the
user ESCAPES into a sale mode in which case the LOCK command
will take effect.
NETWORK LOCK
The master will not display this
message. Also, only scale in
sales mode (REG, MGR, or RPK)
will show this message. Even if
you turn the scale OFF and ON,
or if you unplug it and plug it
from the AC power and/or the
network, the scale WILL remain
in the LOCK mode. The only
way to come out of a LOCK
condition is to issue an UNLOCK
command from the master
scale.

2.5 Unlock Network
Once at the NET: NETWORK MANAGEMENT menu screen, press the 5key. The scale will place the
UNLOCK command on the network queue and wait for you to return to <REG> mode. To return to
<REG> mode, press ESC until you get to <REG> mode.
The LOCK and UNLOCK features are especially useful when you wish to do sales reporting and you do
not want anyone to register any sales before you finish your reports
This is different from the LOCK scale option on the Main menu. The LOCK scale option of the Main
menu only locks the scale in which you select the LOCK scale option. It then requires a level 1
password to unlock as opposed to the Network Lock, which can only be locked and unlocked by the
Master scale.
If you have a scale that is Network Locked and you cannot unlock it through the master, please
contact your Authorized CAS Dealer for service. You may have a network hardware problem, or a
scale hardware problem.
Scale oneself lock/unlock : if you press ALT and 1 key in any program mode, lock command is sent to
oneself. When you want to return program mode, press any key and level one password.
2.6 Check Scale
Once at the NET: NETWORK MANAGEMENT menu screen, press the 6key. You will then see the Check
Scale screen as follows:
The scale number means that the master was able to see that node; “.” indicates a failure to
communicate to that node.
If you have problems with this test, please review the network installation instructions and run the test
again. If a problem persists, contact the CAS Service Department.

3.1 Networked Floating Clerk Option
When using floating clerk mode, make sure that the SAVE, AUTO, and PRE-PACK are off. Also, make
sure that you have not begun an ADD-UP transaction. Generating a floating clerk transaction is the
same as any sales mode transaction except that you do NOT press the PRINT key; instead you must
press one of the Clerk-Speed keys (1 through 4) or press the CLERK key and enter your password. To
total a receipt you simply press the ST/TL key and select your clerk number when requested.
For example, press the MISC By-Weight PLU key, place an item on the platter, enter a price, and then
press the CLERK 1 key. The scale will not generate a label. Go to another scale and do the same
thing. Next, go to a third scale and do the same thing. Finally, while at the third scale, press the ST/TL
key. You will see the following screen:
At this point, select clerk number 1
as this is the clerk under which you
made the 3 transactions. If there
were other clerks on the network
making floating transactions, they
could be totaled from here also.
So be very careful in selecting
YOUR clerk number ONLY!
After selecting clerk 1, press the PRINT key. A screen will be displayed that shows you the status of your
transactions as follows:
If you select YES, then a detailed
receipt will be printed and Clerk 1
transactions for the current
customer will be cleared.
If you select NO, then you can
continue to make floating sales
transactions for that customer.

3.2 Networked Standard Clerk Option
When using Standard clerk mode, make sure that the SAVE, AUTO, VOID and PRE-PACK are off. Also,
make sure that you have not begun an ADD-UP transaction. Generating a floating clerk transaction is
the same as any sales mode transaction; To total a receipt you simply press the ST/TL key and select
your clerk number when requested.
3.3 Non-Networked Floating Clerk Option
When using floating clerk in Non-Network mode, the scale works in the same manner as mentioned
above except that you can only do transactions on one scale. Because the network is disabled for
clerk transactions, any sales transactions that you make in one scale will not be contained at any other
scale. The only advantage to using the scale in this mode, is that you can share one scale with
multiple clerks simultaneously and not have to worry about mixing-up different customer’s sales
transactions. This is true so long as the clerks use their own clerk numbers and NO ONE ELSES!
3.4 VOID Key in Floating Clerk Mode
From the Sales Mode screen, press the VOID key. You will input level 2 -password and get the following
screen:
Select your clerk number and press
the PRINT key.
After selecting your clerk number, you will see the following screen:
Selecting NO will return you to the
Sales Mode screen or list another
page of items if there are any.
Any items listed as number 0 are
previously VOIDed items.
However, after selecting your clerk number, item that be sold recently is voided in 7-segment VFD
version. You will see the following screen.
< VOID Floating Transaction >

If you select YES in graphic version, then you will see the following screen:
Select the number of the item from
the previous screen that you wish
to VOID and then press the PRINT
key.
The number always defaults to the
most recent transaction.
Once you select the number of the item you wish to VOID, press PRINT. That item will appear on the
receipt in STRIKE THROUGH format. It will continue to be listed but you will see that all VOIDed items are
numbered as number 0.
Voiding any number 0 items will not do anything at all.
