WEP Network Security
WEP Types
The RealScan 7802 supports four different types of WEP (Wireless Equivalent Privacy)
encryption in software versions 4.12 and later. WEP encryption is set by the
WEPEncryption mode.

WEP Description
There are four unique encryption keys, WEPKey1 through WEPKey4. Each key contains
10 hex digits for 40-bit encryption or 26 hex digits for 128-bit encryption. Default value
of the keys is a string of zero digits of the appropriate length.
The mode WEPKeyIndex determines which of the four keys is used. The default is
WEPKey1. The selected key must match the type of encryption selected. For example: if
WEBEncryption is set to SHARED128 and WEPKeyIndex is set to WEPkey2, then
WEPkey2 must contain 26 hex digits (or 128 bits). Neither WEPkeyIndex nor the
encryption data can be set by barcode.
Note:
If the encryption type is changed, the RealScan 7802 does not verify that the keys
already stored are appropriate for the new type.
Exception:
If you are using Symbol Technologies access points, they do not support
Shared System WEP encryption.
Setting WEP
Before You Start
1.
The WEP encryption mode and WEP keys for the network you are installing to must
be known.
2.
The WEP encryption mode and WEP keys in the access point and the RealScan 7802
must match exactly or they do not associate.
3.
When installing and configuring a new or replacement RealScan 7802 into a
network running WEP, you must disable WEP at the access point or the RealScan
7802 does not associate with it.
4.
An alternative method is to bring u the RealScan 7802 offline, for example on a
laptop, to set the WEP keys – all the rules still apply but the WEP keys can be
loaded without disabling WEP on your network and UnitConvig can be run locally
rather than on the network server
5.
WEP keys are set with the UnitConfig program.
