3.1. Overview
The communication unit MCOM (Merge/diverge Communication Modem) meet the
requirements of FCC Part15 Subpart C. The FCC ID is as follows.
FCC ID of MCOM: ZBQVEHICLEMCOM
1) Power line communication
MCOM is used for the communication between vehicle and the ground vehicle controller
in the transport system.
The communication signals are overlaid onto the power line for non-contact power
supply to the vehicles. In some systems, a separate signal lines may be used.
The communication unit CMC (Communication Modem Controller) is the groundside
communication unit. CMC is used for the communication between the groundside
vehicle controller and several vehicles.
CMC meet the requirements of FCC Part15 Subpart C. The FCC ID is as follows.
FCC ID of CMC: ZBQVEHICLECMC
MCOM modulate the signals sent from the vehicle and receive the modulated signals
from the ground vehicle controller. MCOM also demodulate the signals sent from the
groundside vehicle controller and transmit them to the ground vehicle controller.
The communication method in use is 2 levels FSK (frequency shift keying).
The communication frequencies are as follows.
From to Frequency
(1) CMC → MCOM： 300.33 kHz
(2) MCOM→ CMC： 353.25 kHz
2) Induction line communication
MCOM is used for the communication between vehicle and other Vehicle in the
transport system.
MCOM outputs the detection signal of one bit in the controller when the existence of the
signal which other vehicle transmitted.
An Induction line is installed on both sides of the track. Therefore one transformer and
circuit are each right and left, and they are equal. It can be changed if one transformer
is used for the reception or it is used for the transmission. A left-right IND-TR is
combined with the loop line, and it can watch each other's transmitting signal. Then, a
trouble such as the breakage of the transformer can be diagnosed.
The communication method in use is Adoption of On Off Keying Method.
The communication frequencies are 88.8kHz.

3.3. Function of each unit
Fig. 2 shows the block diagram of M-COM4.
In addition, the MCOM unit may vary in its outward form depending on the transport
system. However, the internal configuration is common.
All units are connected by the cable.
3.3.1. M-COM4
(Printed circuit board )
M-COM4 is a print board with two communication functions, power line communication
and induction line communication.
Fig. 3 shows the outward form of the printed circuit board M-COM4.
1) Power line communication
M-COM4 board is an interface unit to handle the signals from/to the groundside vehicle
controller.
A signal is transmitted and received by the order of the controller.
This is a modem unit to handle the signals from/to the groundside vehicle controller.
It incorporates a driver that modulates the digital signals sent from the controller to
analog signals and overlay the converted signals onto the non-contact power supply line
or signal line.
It also demodulates the analog signals sent from the groundside vehicle controller to
digital signals and transmit them to controller.
2) Induction line communication
M-COM4 board is an interface unit to handle the signals from/to the other vehicles.
A signal is transmitted and received by the order of the controller.
This is a modem unit to handle the signals from/to the other vehicles.
It incorporates a driver that modulates the digital signals sent from the controller to
analog signals and overlay the converted signals onto the induction line.
It also demodulates the analog signals sent from the other vehicles to digital signals and
transmit them to controller.
The receiving circuit and the transmitting circuit are prepared by the set to the induction
coil on either side. It can change whether a receiving circuit is connected or a
transmitting circuit is connected with the setting signal from the controller to a
right-and-left IND-TR.
Intermittent sending of the 88.88kHz digital signal is carried out from the signal
generating circuit, and a transmitted signal is amplified with transmitting amplifier, and is
transmitted with a coil.
The capacitor for resonance is connected to a coil in series, and voltage amplification of
the 88.88kHz is carried out alternatively.
A receiving circuit converts into a pulse signal the modulation signal received with the
receiving coil, and counts the number of pulses by the signal detector.
If it becomes beyond a value with the number of counts, it will be considered that other
vehicles were detected.

1) The 533usec delay circuit is the circuit to guarantee, from the time that a
request-to-send signal (RTS) outputted from the controller is generated, to the time
that a transmitting circuit attains to the rated value. Time is up in 533usec after RTS
was set to ON, and a clear-to-send signal (CTS) returns to controller.
2) The 200-μsec Delay circuit masks transmitted signal during the time from the end of
the request-to-send (RTS) till the lapse of transmitted signal against received signal,
as the enabled transmitted signal may affect receiving circuit, Resulting in erratic
output. This delay circuit times out in 200μsec after the RTS is ended.
3) After receiving data from the groundside vehicle controller, please prepare the
waiting time for 833 seconds or more with the software by the side of ATI. When
fewer than this time, it is because a NBV-BC substrate cannot receive data.
3.5.2. Induction line communication
Control/modulating of communication use the connector CN39.
A communication-Logic table is shown in the Table. 2.
Please control signal according to the communication table shown in Table. 2.
In addition, all the signals are TTL-Level.
For example, when you want to transmit from a left IND-TR and to receive from a right
IND-TR, please make a signal into

When M-COM4 breaks down, the breakdown signal is output. Breakdown signals are 10
pins of CN39.
The detection of the breakdown by feeds back the transmission signal of 88.8kHz to the
reception circuit, checks, and when the signal cannot be received though it transmits, is
breakdown output.
The main content to break down is disconnected IND-TR, and is a breakdown of M-COM4
internal circuit, etc.
The pulse signal that always repeats ON/OFF of each 30msec from 9 pins of CN39 is
output. The controller can confirm whether the M-COM4 circuit operates by observing this
signal.

5. Error process
[Note.1]
Before servicing MCOM，always shut off the power supply.
[Note.2]
If the communication signals are overlaid onto the non-conductive power line, also shut off
the power source of the non-conductive power line before starting maintenance on
MCOM.
<Power net line Communication error trouble shooting>
Communication error
Is the Controller sending communication signals？
Check the settings for the Controller.
Are the power indicator lights of M-COM4 illuminated？
Is the power supply of DC24V,5V and ±12V connected？
Turn the power supply OFF. Is the input resistance of the DC power
almost 0 ohm？
Replace the DC power supply.
Is the connection between the controller and M-COM4 normal？
Restore connection.
Is the connection between the COM-TR and M-COM4 normal？

6. Cautions on Use
(1) If the noise of a power net line is large, since communication quality will deteriorate,
please reduce a noise.
(2) When the noise generation source near 100kHz is in near, in order that induction line
communication may cause incorrect detection, please remove a noise generation
source.
(3) Don't arrange a choke coil and a power system switching circuit near the IND-TR.
(4) Since the pulse signal of a self-vehicle and other vehicles may synchronize, please be
sure to perform a pulse output timing change to different timing for every cart during
transmission from the exterior in induction line communication..
(5) If the communication signals are overlaid onto the non-conductive power line, also shut
off the power source of the non-conductive power line before starting maintenance on
MCOM.
