GENERAL DESCRIPTION
The MAC-32-OD is a thirty-two output control unit that offers a wide choice of communication options.
Listed below are the major features of this versatile unit.
Outputs
The MAC-32-OD has 32 form ‘C’ relays that can be controlled by a remote terminal. Connection to
these relays is made via two 50 pin telco connectors on the rear of the unit. The status of each of the
32 relays is displayed by 32 LED’s (two banks of sixteen).
Communications
The MAC-32-OD offers both RS-232 and RS-485 communications facilities. An internal modem and
software options are available.

CONFIGURATION
Setting The Mac Address
The MAC-32-OD requires an Address to be set for each MAC device in the communication system, prior
to use. The address of the MAC-32-OD MUST be set to allow proper communications between the
devices. This address is set using DIP Switch S3. Up to 255 address combinations can be selected,
using eight DIP switch positions. Addresses are set in a Binary Format as follows:
DIP
Position Binary Open = 0
1 1 Closed = 1
2 2
3 4
4 8 Example: 1 2 3 4 5 6 7 8
5 16 0 1 0 1 0 0 0 0 = Address 10
6 32
7 64
8 128
Note
Address 0 is reserved for Master Devices and should not be used.
COMMUNICATIONS PORTS RS-232 AND RS-485
These ports are provided for use with all MAC-32-OD functions. As an example, a MAC-32-OD can be
connected to other MAC devices using the RS-232 or RS-485 ports.
COMMUNICATION CAPABILITIES
The MAC-32-OD offers one active communication port that can be jumper set for RS-232 or RS-485
operation.
Com 1 is the primary communications port that can be configured for RS-232 or RS-485. In RS-485
mode, the MAC can communicate up to 5000ft. over a pair of wire lines.
Use Jumper JP5 located on the left side of the PCB to select the desired mode. See the table below for
proper jumper settings.
For external modem communications install the jumpers at the positions shown for the RS-232 mode.
This is the factory setting.

RELAY OUTPUT RATING
The relays used in the MAC-32-OD are rated 1 Amp @ 24 Vdc or 0.5 Amp @ 125 Vac.
Note
When switching inductive or lamp loads, appropriate contact suppression is needed. If you have any
questions, please consult with Dataprobe.
INSTALLATION
Basic installation of the MAC-32-OD consists of connection to the controlled output relays and the
communications channel.
Output Relay Connectors
Two 50 pin Telco connectors are provided for connection to the Output Relays. The pin-outs of these
two connectors are the same, the first, for circuits 1-16 and the second, for 17-32.

Spare Relay
The spare relay (fail safe) provides a means of connecting an external audible or visual alarm device.
When a relay output is activated, it will cause the spare relay to energize. The spare relay will remain

energized unless one of two events occur; all relay outputs are in relaxed state or the test push-button
has been depressed.

TEST PUSH BUTTON
The test push button is located on the front panel. The test push button has the following three
functions:
1. Mute: Pressing the button less than 2 seconds causes the spare relay to de-energize.
2. LEDs/Output Test: Pressing the button more than 2 seconds causes all the relay outputs to
energize and LEDs to light.
3. Communication test: Double clicking the button will cause the communication link to be tested. If
test pass, all the LEDs of the MAC-32-OD will flash three times. If test fails, only LED 1 flashes
three times.

MODEM COMMUNICATIONS WITH THE MAC-32-OD
The MAC-32-OD devices can communicate using an external modem or an optional V.22 bis internal
modem that plugs directly into the MAC-32-OD.
The modem of the MAC-32-OD can be called to control the relay outputs.
When an external modem is used, the RS-232 output from the modem must be connected to the
COM-1 port of the MAC-32-OD marked '232'. A converter cable and an RJ-45 to DB-25 adapter, model
MA-K is included.
When the internal modem is used, the phone line is connected to the LINE (RJ-11) jack. To insure
proper operation of the internal modem the calling modem MUST be set in the normal direct mode, and
non nmp or data compression mode. See your modem manual. To avoid problems, it is best to use a
standard V.21 or V.22 bis modem when calling the internal modem.
Described below is the method used to store the outgoing phone number in the MAC-32-OD.
Programming By Calling the Modem of the MAC-32-OD with Another Modem
Using a PC with a modem and any communications program, call the MAC-32-OD using the following
communications format.
2400 baud, 8 bits, no parity, 1 stop bit. (8N1). (Factory Set)
Once communications is established, type 'P', <Enter>.
A prompt appears on the screen; ENTER PHONE NUMBER>. At this prompt, enter the outgoing
number the MAC-32-OD will dial to establish communications. Up to 20 digits followed by a carriage
return (Enter). If a PBX is used, separate the access code (such as a 9 for an outside line) from the
phone number with commas for a pause. Add 1 for long distance if required.
Example: Typical format for dialing an outside long distance line on PBX.
9 , 1XXXXXXXXXXXXXXXXX
Access Code
Pause
Long Distance
Phone
Note
X = numerical digit or -
After entering the telephone number, disconnect the remote modem to return the MAC-32-OD to its
normal operating mode.

TO BE WELL CONNECTED IS VERY IMPORTANT !!!
When connecting equipment to the MAC-32-OD, it is imperative that the correct connector pin-outs and
cable type are used.
1> For the RS-485 six position RJ-11 jack, DO NOT use a standard telephone type cable that reverses
the connections between ends. Use only a DATA type cord that maintains the same pin positions at
each end to preserve the correct polarity required between connected equipment.
2> For the RS-232 eight position RJ-45 jack, USE ONLY a data type cable and observe the pin
positions as shown below for this type of jack. The relationship between the RJ-45 jack and a standard
RS-232 connector pin out for MAC-32-OD is shown on page 6 of this manual.
3> Under NO circumstance ever insert or use an RJ-11 plug in an RJ-45 socket. The pins in the socket
will be deformed, leading to poor connections.
