INTRODUCTION
Your new modem is one of the most technologically advanced available. It combines
high-speed data, fax, voice and ASVD (Automatic Simultaneous Voice and Data)
functions in a single unit. The modem has been designed to complement the
Mitsubishi FX and A ranges of PLC’s, and provides a number of unique telemetry
features for handling data transfers between PLC’s.
The modem is capable of operating at data speeds of 33.6Kbps and has the ability to
store telephone numbers, fixed messages, etc.
This manual is divided into eleven sections covering (1) Modem Standards and
Compatibility, (2) Getting Started, (3) Enhanced Functions, (4) Troubleshooting,
(5) AT Command Set, (6) Support, Service and Compliance details, (7) Technical
Details, (8) Technical Specification, (9) Accessories, and (10) PLC Programming
Examples.
Please be sure to read section two carefully before installing your modem.

Section 2 – Getting Started
2.1 Installation & Removal
2.1.1 Installation – A2S Version
i) Locate in a vacant I/O position, preferably adjacent to the Comms Link
module (A1SJ71C24-R2/A1SJ71UC24-R2/A1SJ71QC24-R2).
ii) Insert the module mounting-hook into the slot below the chosen I/O position
on the A1S Base and push the top of the module forward until fully located.
iii) Secure the module with the retained mounting screw at the top.
NOTE: Installing the A2S-MODEM on the backplane does not connect to the Bus or
take power or occupy I/O addresses. To avoid loosing any I/O addresses, assign “S0”,
under Parameters in the PLC software, for that slot.
2.2.2 Removal – A2S Version
i) Unscrew mounting screw then tilt the module backwards against the
mounting hook until clear of the A1S Base connector.
ii) Lift upwards and remove the module hook clear of the slot.
2.1.3 Installation – DIN Version
i) Locate the top of the DIN rail clip onto the DIN rail and push the module
down until the clip is secure.
2.1.4 Removal –DIN Version
i) Lever the bottom of the module upwards until the clip releases and un-hook
from the top.
2.2 Connection and Wiring
2.2.1 Connection to a Link module (eg. A1SJ71C24-R2)
i) Connect the 9-pin to 9-pin cable type (MODEM-R2-CAB), between the
Data RS232 port on the front of the DIN-MODEM-2 or A2S-MODEM and
to the RS232 connector on the front of the A1SJ71C24-R2 link module.
ii) Connect the telephone lead provided by plugging in the RJ11 type plug into
the socket labelled LINE, making sure that the connector is properly latched.
iii) When simultaneous voice and data is required, connect a suitable handset or
headset by plugging into the socket labelled VOICE.
iv) Connect a 24V or 12V dc supply via the connector provided. The dc
polarity is not important as it is corrected within the MODEM.

2.2.1 continued
NOTE 1: Modems cannot be connected directly to the CPU programming port.
NOTE 2: Set the Link module to protocol 1, Write during run, 9600 baud, 8 data bits,
No parity, 1 Stop bit and Sum Check ON. Eg. MODE=1, SW04,05,07,08 &12 = ON,
all other switches OFF. After changing these switches turn the power to the PLC off
and back on alternatively reset the CPU.
2.2.2 Connection to FX2N-232-BD
i) Connect a 9-pin male to 9-pin female cable, type MODEM-FX2-CAB or
MODEM-PC9-CAB, wired to the schematic shown in Section 7, between
the Data RS232 port on the front of the MODEM and the serial port at the
top of the FX2N-232-BD plug-in module.
ii) Then follow the instructions in Section 2.2.1 ii) to iv) above
2.2.3 Connection to MAC 50/90 and E range of HMI’s
iii) Connect a 9-pin male to 9-pin female cable, type MODEM-MAC-CAB,
wired to the schematic shown in Section 7, between the Data RS232 port on
the front of the MODEM and PRINTER serial port at the back of the MAC
or E range terminal.
iv) Then follow the instructions in Section 2.2.1 ii) to iv) above

2.2.6 Wiring
24V dc Supply A2S and DIN Versions
i) Wire 24 dc from a suitable supply, usually from terminals on a nearby
module to the miniature screw terminal plug provided.
ii) Check the specification for the 24V supply before making connection.
However, reversing the polarity of the dc will cause no harm.
12V dc Supply DESK Version
i) Plug the 12V dc power supply provided into a mains supply and connect
the jack plug into the connector at the rear of the MODEM.
2.3 Initial configuration
i) Set the Modem to the correct local protocol (see 5.9 for a list of codes),
with the command:
AT%ADP=x (where x = protocol setting)
ii) Read section 3.1 for more details.
