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 , 1 XXXXXXXXXXXXXXXXX

After entering the telephone number, disconnect the remote modem to return the MAC-32-OD to its
normal operating mode.
