9560 Transaction Manager User’s Manual
Sample Program 1
9-10
The digits correspond to the inputs as shown below:
Third input
J3
0 1 1 Register #0
Second input
J2
First input
J1
9560-40U
For example, if the #0 register contains 011, it would indicate a signal at the
first and second inputs, but none at the third input.
• Clears the sense inputs
For a complete description of the command syntax, see “LED/Relay Control”
in Chapter 8. For a description of commands for the magnetic card reader, see
“Magnetic Card Reader Commands” later in this chapter.
In this example, the 9560 controls access to a restricted area. If the user scans a
badge with an authorized number, the 9560 responds by actuating a relay that
may be connected to a door lock. An invalid badge number does not unlock the
door.
This program is appropriate for a configuration where the 9560 is not
connected to a host computer. Instead, the IRL program contains a list of all
valid badge numbers that are sequentially checked against the scanned badge.
You can use this programs as is, line by line, with or without the comments.
