Concepts of Operation
Transmit ID
On the tool bar of the Administration Software, there is a drop-down list titled
Transmit ID
(see Figure 10 below). The ID number that appears in the field is the
reader with which the software currently is communicating. For this reason, each
reader must be assigned a Network ID, even if your installation consists of a single
unit (the default setting is 0).
Figure 10: Transmit ID Drop-down
A special transmit ID number, “-1”, is assigned as a broadcast ID. All units on the
current COMM Port will respond to this broadcast ID. For functions labeled
“broadcast” the software uses the broadcast ID and all readers on the network will
accept these commands. Using Broadcast commands is only recommended for
advanced users. (See Appendix B for further understanding of the benefits and
issues with Broadcasting commands.)
If the transmit ID is set to a number that is not assigned to any unit on the network,
the software will report that there is no communication.
If two units on the network have the same ID assigned, there also will be
communication problems, since both units would respond to commands sent to
that ID. This causes the information packets to “collide” and become jumbled,
resulting in communication errors.
Ports
Bioscrypt readers “talk” to the VeriAdmin Software using either the Host or
Auxiliary (AUX) port. The Host port may be configured to use RS-232 or RS-485
protocol. The Host port is connected through the pigtail-wiring bundle at the back
of the unit. Different wires are used for RS-485 versus RS-232. The Aux port is
accessed using the RJ11 jack at the bottom of the VeriProx. Please refer to the
VeriSeries Installation Guide
(included on the Bioscrypt CD) for details.
Serial Port Settings and Baud Rates
Once the reader(s) have been connected to the PC, the next step is to identify
which ports on the PC are talking with which readers.
