| This
page describes how to properly wire the MCAS and interface with your
hardware. Interface to the MCAS controller occurs through two 40-pin
header sockets: J4 and J5. (Refer to the MCAS
User Manual for pin-outs and pin descriptions.)
Kadtronix
now offers a Field Wiring Terminal Board (FWTB) for
easy interfacing. Features screw terminal block, power switch, flashing
LED indicator, AC power jack, and onboard door activation relay.
The
following schematic image illustrates a typical MCAS application including
card-reader, host-control interfacing, and door-activation connection.
| Note
1: Card-readers have different pin-outs and voltage requirements.
Consult your specific device's documentation for hook-up information.
Note
2: Also required (not shown in the diagram above) are pulldown
resistors at MCAS controller signals PD0 (J5-19), PD1 (J5-20), and PD2
(J5-21). Refer to the MCAS
User Manual for details.
Note
3: The diagram above indicates a RS-232 card-reader. A
TTL (clock/data) reader, proximity reader, or barcode scanner may
also be used. Refer to the MCAS
User Manual for details. The dashed line indicates a port-powered
connection where the reader device obtains its power from the serial port.
If using a MagTek serial RS-232 card-reader such as part number 21040075,
use one of the following wiring guides: |

| Host
communication requires a RS232-to-RS485 converter. The diagram below indicates
two types of converters made by B&B
Electronics: models 485BAT3 and 485SD9TB. Both devices are port-powered
and feature optional +12VDC external power connections. |
| The
Field-Wiring Terminal Board (FWTB) allows easy interfacing and provides
two header connections for mating with a MCAS controller. In addition,
it provides 16 screw terminal connections for interfacing card reader,
RS-485 cable, and power supply. The terminal board also provides
power switch, flashing status LED, AC jack, and door activation relay.
Kadtronix
now provides a special Ethernet (TCP/IP) option for LAN users. This
new feature (FWTB option 3) includes integrated RJ-45 jack for easy
interfacing. |
| All
soldered FWTB components are optional (except header connectors and terminal
block) and need not be populated if desired. A "bypass" jumper" can
be soldered in place of the power switch. The following diagram shows
orientation and placement when attaching a MCAS controller to the FWTB. |
| The
following image illustrates hookup and interfacing details. (FWTB
shown without MCAS controller for clarity.) |

(
Optional A/C power jack may be used instead of power input at terminals
1 & 2 if desired.)
