Configuring the Encompass 4 Reader
8-13
The following sections contain procedures to set some of the parameters that are
commonly changed to meet the requirements of a specific site. Procedures are
listed in alphabetical order by parameter.
Appended Tag Data
Use this procedure to set appended tag data parameters using the terminal emulation
application. See
“31N Append Auxiliary Information Selection” on page 7-9 for more
information.
To set appended tag data parameters
1. Ensure that the host computer is in command mode.
2. Enter command #311 to append auxiliary information or command #310 to
have no auxiliary information appended (factory default). Press ENTER.
ID Separation
The host can select a unique ID separation of one ID or two IDs. The reader default
operation is for a unique ID separation of one ID and a uniqueness timeout of
two
minutes. You can disable the uniqueness check using command #40 Transmit All
ID Codes. In this case, every tag ID received is transmitted without regard to unique
-
ness. You can reinstate uniqueness checking with commands #4100 or #4101 Select
ID Separation.
Note: The dual-protocol Encompass 4 Reader internal timing varies depending on
the operative tag read mode and the type of tag in the read field.
See section “40 Transmit All ID Codes” on page 7-11 and section “410N Select
Unique ID Code Criteria (Anti-passback Feature)” on page 7-11.
To set ID separation parameters
1. Ensure that the host computer is in command mode.
2. Enter command #4100 to select a separation of one ID; enter command #4101
to select a separation of two IDs. Press ENTER.
Reports
The Encompass 4 Reader can be configured to transmit presence without tag reports
and input status change reports. A presence without tag report is transmitted in data
mode only, and only if the system has a presence detector. This report is sent if a pres
-
ence is detected without the detection of a valid tag ID. See sections “529 Display
Presence Input Status” on page 7-25 and “690N Select Presence Without Tag Report
Option” on page 7-44.
If configured with command #82N Select Input Status Change Report Option to
transmit input status change reports, the reader will transmit a message to the host
computer any time the inputs change state. Input status change reports are transmitted
