<strong>CONTROL</strong> <strong>LINE</strong> <strong>APPLICATIONS</strong> <strong>AND</strong> <strong>WIRING</strong><br />
INTRODUCTION<br />
One relay control output line is standard on all <strong>LINX</strong> II, III, & IV terminals. An additional 5<br />
relay control lines can be purchased on <strong>LINX</strong> III & IV terminals. There are 6 standard relay<br />
control lines on a <strong>LINX</strong> V.<br />
The control lines have been used in some of the following applications:<br />
Access Control (doors, turnstiles, gates),<br />
Alarm systems,<br />
Conveyor Control,<br />
Fabric Cutting,<br />
Light Control,<br />
And many others<br />
The control lines are able to supply 22mA of current at 5VDC. This is a TTL level signal which<br />
must not be exceeded, or component failure may occur! The control lines must always be<br />
isolated from the ultimate load through a solid state relay. Conventional coil type relays will not<br />
work! Specific part numbers for relays are quoted later in this document.<br />
Control lines #1 functions somewhat differently than the other 5 control lines, so they are treated<br />
separately in this discussion.<br />
Control Line #1 (Standard Equipment)<br />
Control line #1 is available at pin 8 of the EXD connector on both <strong>LINX</strong> II & III terminals. On a<br />
<strong>LINX</strong> IV & V terminal it is located at pin 1 of the EXT connector. In its ON state, it supplies<br />
+5VDC, and in its OFF state it goes to ground, or zero volts.<br />
Another important consideration for this control line is that it comes up in the ON state when the<br />
terminal is powered up. Therefore, one of the first housekeeping chores which a program should<br />
do is to turn OFF the control line. See the <strong>LINX</strong> III Program Development Guide, LinxBASIC<br />
Version or the BARCON Language Reference for specific information on activating the control<br />
lines.<br />
The EXD port requires a Switchcraft (Chicago, IL, (773) 792-2700) part number 15BL8M male<br />
connector. This can be obtained either from <strong>LINX</strong> directly, or from Wholesale Electronic<br />
Supply. Contact Switchcraft directly for the name of international distributors.<br />

Control Lines #2-6<br />
When ordered on a <strong>LINX</strong> III, the extra control lines are accessible on the COM2 connector,<br />
regardless of whether a serial port was ordered for the terminal. The extra control lines simply<br />
occupy the unused pins 1, 4, 6, 8, and 9, leaving pins 2, 3, and 5 in case an RS-232 port was<br />
ordered. Because an RS-422 port would require some of the control line pins, it is not possible<br />
to order both the extra control lines and the RS-422 COM2 port options on the same terminal.<br />
An important difference is that these extra control lines operate in a reverse sense. That is, ON is<br />
zero volts, and OFF is +5VDC. Should it be desirable to have these control lines operate in the<br />
same sense as Control Line #1, the relay connections can be reversed as follows: Connect the +<br />
terminal of the relay to pin 1 of the EXD connector, which has a constant +5VDC available.<br />
Then connect the – terminal of the relay to the appropriate COM2 pin. This will then allow the<br />
relays to operate in the ON state, and shut OFF in the OFF state.<br />
These control lines do not come up in the ON condition upon powerup. See the <strong>LINX</strong> III<br />
Program Development Guide, LinxBASIC Version or the BARCON Language Reference for<br />
specific information on activating the control lines.<br />
Relays<br />
Relays must be of the solid state (SCR or TRIAC) variety because these require much lower<br />
current than the coil type relays. Crydom Corporation (9525 Chesapeake Drive, San Diego, CA<br />
92123, PH. 858-715-7200, FAX 858-715-7280) makes relays which we have tested and found to<br />
work effectively with the control lines. Because these relays use semiconductors to switch, you<br />
must select a relay which matches both the voltage range and the voltage type. (An AC relay<br />
will not switch DC current, or vice versa.) The following relays are recommended:<br />

Additional Control Line<br />
The additional control lines toggle in reverse of the control line located<br />
in the EXD connector. The additional control lines will output +5VDC<br />
when set ON and +0VDC when set OFF. When power is off, there is<br />
no voltage across the relay.<br />

<strong>LINX</strong> III Control Connections<br />
The control line is held at +5VDC when<br />
not activated (OFF). When activated (ON)<br />
the line is lowered to ground. These voltages<br />
are referenced to pin 2 (signal ground) on<br />
the EXD connector.<br />
