3.3. Function of each unit
3.3.1. CMC-BC
(Communication Modem Controller ：Base Controller)
This is an interface unit to handle the signals from/to the vehicle controller. It also serves as the
multiplexer for several CMC-BM units.
CMC-BC can work in two different modes, master mode and slave mode. It allows the user to use
the multiple units according to the scale of the conveyance system.
The CMC-BC unit may vary in its outward form depending on the conveyance system. However,
the internal configuration is common.
Figure 4 shows the block diagram of CMC-BC.
Figure 5 shows the outward form of the CMC-BC’s main printed circuit board NBV-BC.
Figure 6 shows for example the outward form of the CMC-BC unit.
3.3.2. CMC-BM
(Communication Modem Controller ：Base Modem)
This is a modem unit to handle the signals from/to several vehicles.
It incorporates a driver that modulates the digital signals sent from CMC-BC to analog signals
and overlay the converted signals onto the non-conductive power line or signal line.
It also demodulates the analog signals sent from the vehicles to digital signals and transmits
them to CMC-BC.
The CMC-BM unit may vary in its outward form depending on the conveyance system. However,
the internal configuration is common.
Figure 4 shows the block diagram of CMC-BM.
Figure 7 shows the outline form of the CMC-BM’s main printed circuit board BV-BM2.
Figure 8 shows for example the outline form of the CMC-BM unit.
3.3.3. CMC-TR
(Communication Modem Controller ：TRansformer)
Transmission transformer overlays the signals from CMC-BM onto the non-conductive power line
or signal line.
The reception transformer receives the signals from vehicles overlaid in the non-conductive
power line or signal line.
Figure 9 shows the outer forms of the transformers.

3.4. The Block Diagram of CMC
Fig. 4 The block diagram of CMC
CMC is a communication unit between a vehicle controller and vehicles.
The communication signals modulate current signals of a power line/or signal line .
The vehicle controller controls vehicle movement by transmitting and receiving this signal.
[CMC-BC]
Communication signals from the vehicle controller are transmitted to CMC-BC as RS232C or
RS485. When communication signal is “1”, The Modulator of CMC-BC modulates 285.7 kHz FSK
signal frequency. When communication signal is “0”, The Modulator of CMC-BC modulates 315.8
kHz FSK signal frequency.
The modulation signal is transmitted to CMC-BM through a line driver of RS485.This modulation
signals transmit to CMC-BM as RS485.
[CMC-BM and CMC-TR]
The modulation signal is received from CMC-BC through a line receiver of RS485.
TX Amp of CMC-BM is full bridge inverter. The modulation signals are converted into a gate
signal of full bridge inverter. The inverter transmits the modulation signal through resonance
circuit and CMC-TR.

3.6. FCC standard
The transmission assembly in the communication unit CMC meets FCC Part15 Subpart C as the
intentional radiator.
FCC ID of CMC： ZBQVEHICLECMC
FCC WARNING
Changes or modifications not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
- Properly shielded and grounded cables and connectors must be used for connection to
vehicle controller and CMC-BC in order to meet FCC emission limits.
- Properly shielded and grounded cables and connectors must be used for connection to
CMC-BM and CMC-BC in order to meet FCC emission limits.
- TX transformer of CMC-TR with ferrite core must be used for RF interference suppression.
Note:
This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely
to cause harmful interference in which case the user will be required to correct the interference
at his own expense.
[Note.1]
The FCC certificate position may vary because different case materials and shapes are adopted
for different customers.

4. CMC-BC Board Setting
4.1.
CMC-BC Board Check
4.1.1.
Purpose
Check for short circuit and earth ground fault before energizing CMC-BC board for the safety.
4.1.2. Required Materials
• Wiring Diagrams, Checklist
• Multimeter, Phillips-head Screw Driver (+2), Wrench, Tape Measure
• Vehicle
4.1.3. Tips, Precautions and Prohibited Actions
<Precautions>
・ Set the barricade with colored-cones and safety bars around the work area.
・ Measure the short-circuit and the earth fault after confirming it has no voltage.
<Prohibited Actions>
・ Work in the energized status is prohibited.
4.1.4. Procedures
A) After confirming that the CMC-BC board’s CPM is OFF (see Fig. 11), check for short circuit
and earth ground fault on the secondary side of the CPM. (Make sure you confirm that the
AC power voltage is zero V before measuring the resistance. Since the primary side of the
CMP is connected to the indicator lamps, short circuit check should show 3 - 4KΩ. The
ground fault shall be open.)
B) Check for short circuit and earth ground fault on the secondary side of CP1 through CP8.
The CPM must be OFF at this time. Both short circuit and earth ground fault checks on the
secondary side of CP1 through CP 8 shall indicate open.
C) Confirm that all connectors on the NBV-BC printed circuit board are firmly connected. Lock
the connecters with connector fastenings. (If any connecter is loose, communications will
fail.)
D) Firmly insert the 232C cable from the OHVC to CN12 on the NBV-BC printed circuit board.
(If loose, communications will fail.)
E) Set the NBV-BC P board’s DIP switches (SW 1, 2 and 3) in accordance with provided
specifications. (If they are not set, communications will fail.)
F) Measure the voltage of primary side of CPM
G) After confirming that everything is good, turn ON the circuit breaker on the power distribution
panel to energize the CMC-BC board.
<Prohibited Actions>
Hereafter, Work in the energized status is prohibited.

(4) Procedures for BV-BM3 receiving waveform adjustment are as follows.
Adjust the waveform level with variable resistance (VR1, VR2, VR200 and VR202) as
you monitor the receiving waveform. Adjust variable resistance per one division in
order of VR1→VR2→VR200→VR201.
Receiving waveform criteria;
Minimum level of receiving waveform communication speed :19.2kbps 7V±0.5V

* If the receiving level does not decrease, rotate all variable resistance fully counter-clockwise.
* Lines with communication wires
If the receiving level does no decrease to the specified value, decrease the number of
communication wire turns on the communications transformer. In case the minimum
receiving level is 2V or less, increase the number of communication wire turns on the
communications transformer.
