Page 10: Installing The Terminal Block
Installing the Terminal Block Note: For IP54 compatibility, mount the terminal block with the connector side facing toward the floor. You need these tools to install the terminal block: • Drill and drill bits appropriate for the mounting surface • Small straight-slot and Phillips screwdrivers •... - Page 11 • For the IF61, connect the cable (P/N 236-057-001) to the GPIO port. • For the IF5 or IF30, connect the cable (P/N 236-057-001) to the Control Port. • For the IV7, connect the cable (P/N 236-089-001) to the Data Port on the IV7 and to the COM port on the host PC.

Page 12: Connecting To The If5, If30, And If61 Readers
“Connecting To the IV7 Vehicle-Mount Reader” on page 23. About the Reader GPIO Interface The IF5, IF30, and IF61 readers have four general purpose input and output interfaces. Each interface is electrically isolated from the reader and designed for low voltage DC loads. The readers can also supply 12 VDC at 0.5 A to external devices. - Page 13 The input terminals access the four general purpose inputs on the reader. Each of the inputs is compatible with input signals of 10 to 48 VDC. Each input terminal includes a green indicator LED that lights up when the input circuit is energized. 12 VDC Reader Interface...

Page 14: Reader Powered Input
Reader Powered Input Supplying the input interface with power from the reader is the easiest way to connect a control to an input terminal. Each input terminal ships with a jumper wire between the -Input and Ground posts. If the input device is a switch closure, connect the other side of the switch to the +12 V post as shown in the next illustration. -
Page 15: Isolated Input Interface
Isolated Input Interface Use this method to minimize noise caused by distance or grounding characteristics. The isolated input avoids induced noise by referencing a remote input to chassis return of the reader. Use a twisted pair cable to connect the input device to the terminal block to further suppress noise. -
Page 16: Open Collector Input Interface
Open Collector Input Interface You can connect the input to an open collector interface of an external device, which suggests that the grounds are tied together for the two systems. Because the common ground can be a source of input noise, follow good grounding practices for both the reader and the input device. -
Page 17: Connecting Devices To The Output Terminals
Connecting Devices to the Output Terminals Each output terminal has four terminal posts: • 12 V • +Output • -Output • Gnd (Ground) The output terminals allow you to access the four general purpose outputs on the reader. Each output is optically isolated from the reader, polarized, and rated for 5 to 48 VDC at 0.25 A. -
Page 18: Switching The High Side Using Reader Power
Because the outputs are optically isolated, you can configure each one to switch the high side or the low side of the load. You can power the load directly from the reader or from an external power supply. The next examples illustrate several ways to connect controls to the output terminals: •... -
Page 19: Switching The Low Side Using Reader Power
Switching the Low Side Using Reader Power For low side switching applications, lamp power is routed to all the lamps in common and the low side of the load is routed to the switch. To configure an output terminal for low side switching, use the jumper to short the -Output and Ground posts together as shown in the next illustration. -
Page 20: Switching The High Side Using External Power
Switching the High Side Using External Power To switch the high side of an externally powered load, remove the output terminal jumper. You should also connect the reader ground to the ground system of the external power supply, which enables the output terminal LED (not shown in the illustration). -
Page 21: Driving A Dc Relay To Control An Ac Load
Driving a DC Relay To Control an AC Load The reader outputs can only switch DC loads, but can drive relays that control AC loads as seen in the next illustration. AC motor -Output, 250 mA max. 120-230 Ground External relay Driving a DC Relay: The external relay provides dry contacts for controlling the AC motor. -
Page 22: Sample System Diagram
If your system needs more than +12 VDC at 0.5 A, you can connect an external power supply to the +12 V and Ground posts on the power terminal. The external supply will power the external loads, and that power will be available at all +12 V posts on the input and output terminals. -
Page 23: Connecting To The Iv7 Vehicle-Mount Reader
Connecting To the IV7 Vehicle-Mount Reader Connecting GPIO devices to the IV7 reader requires special considerations. The IV7 GPIO: • inputs are limited to 40 mA total. outputs are limited to 50 mA total. • • does not provide 12 VDC for powering external devices. To connect the terminal block and GPIO devices to the IV7, use a voltage conditioning network as shown in this sample schematic: External +12 VDC... -
