Step 1: Ensure software version of Mitsubishi MR-J4 servo amplifier is version C2.
The version can be check under Diagnosis > System Configuration of MELSOFT MR Configurator 2 Software
NOTE: ITF-21-BISS-MIT is only supported by two series of MR-J4 servo amplifier: MR-J4-_B-RJJ001 and
MR-J4-_B-RJJ021
Step 2: Ensure firmware of ITF-21-BISS-MIT can support the BiSS C encoder used. The firmware setting of ITF-21-
BISS-MIT in default supports 22-bit rotary BiSS C encoder and Mitsubishi 2 wire (half duplex) communication.
To use ITF-21-BISS-MIT with other number of bits of position data of rotary BiSS C encoder or Mitsubishi 4 wire
(full duplex) communication, user need to configure the setting of ITF-21-BISS-MIT with PC software accordingly
via USB-C.
Refer to PC Software section for setting configuration. To get the PC software, please contact Akribis System
sales. The detail of setting supported can be found in Setting Configuration section.
Step 3: Prepare the necessary cables as shown in Quick-Start Guide and connect them accordingly as per High Level
Schematic of Typical Application
Step 4: Configure MR-J4 Driver settings accordingly.
Step 5: If red LED turns on and MR-J4 alarm is triggered, it means Mitsubishi alarm and ITF-21-BISS-MIT alarm is
triggered.
The alarm number is corresponded to the alarm number shown in Mitsubishi Alarm Information (ALMC) of
Mitsubishi Serial Interface section.
If red LED turns on but MR-J4 alarm does not triggered, it means ITF-21-BISS-MIT alarm triggered. Refer to
Adapter Alarm for detail explanation of ITF-21-BISS-MIT alarm error.
The root causes of all these alarms can be checked with PC software, Interface Adapter Configurator. Refer to
diagnostic part of PC software section.

5. Architecture of Adapter
ITF-21-BISS-MIT (BiSS C to Mitsubishi Serial Adapter) acts as BiSS C Master to sample position data from BiSS C
encoder (Slave) and at the same time also acts as Mitsubishi Serial Slave to provide position data sampled to MR-J4
driver (Mitsubishi Serial Master) whenever the driver requests from it.
BiSS C Interface
The BiSS C Master module of ITF-21-BISS-MIT use BiSS C (unidirectional) serial protocol. It is designed to work in a
point-to-point configuration and must be installed in a “single Master, single Slave” network. Besides, it does not support
line delay compensation.
The interface consists of two unidirectional differential pair of lines:
“MA” line transmit clock which is the position acquisition request from BiSS C master of ITF-21-BISS-MIT to encoder.
“SLO” line transfers position data from encoder to BiSS C master of ITF-21-BISS-MIT, synchronised to “MA” clock.
Data Format
Refer to the official BiSS website for more information which is not listed in this manual
www.biss-interface.com
Note:
Ack
During this period, the encoder is calculating and generating position data. “Ack” duration vary with encoder used.
Error (1-bit)
Active low. ‘1’ indicates normal, ‘0’ indicates error.
Warning (1-bit)
Active low. ‘1’ indicates normal, ‘0’ indicates warning.
CRC (6-bit)
Error detection checksum calculated from position, error and warning data. It is transmitted with MSB first and inverted

Timeout
If the encoder is not yet ready for the next request cycle, it sets “SLO” low during timeout period. The timeout duration
varies with encoder used. Some encoder allowed user to configure the timeout period. The user can configure the
timeout period to minimum to achieve higher request cycle rate
Line Delay
Signals travelling between master and encoder experience significant time delay due to the cable length. The time delay
has no effect at low clock speeds (where the time delay is much shorter than the clock period). However, for high clock
speeds, the line delay will become significant and cause the data transmission to violate the protocol rules.
Due to the ITF-21-BISS-MIT (master) do not support line delay compensation, thus slower clock frequency must be used
for long encoder cable length. The default MA clock frequency used by adapter is 1MHz. With this clock frequency, the
maximum cable length that can be supported without line delay compensation is 20m.
Request Cycle Rate
BiSS C cycle period is the time between the first falling edge of MA clock to rising edge of SLO timeout. This determine
the max request cycle rate.
The BiSS C cycle duration can be calculated from the formula below:
𝑩𝒊𝑺𝑺 𝑪 𝒄𝒚𝒄𝒍𝒆 𝒅𝒖𝒓𝒂𝒕𝒊𝒐𝒏 = (𝟏𝟏. 𝟓 + 𝒏)𝑻 + 𝒂𝒄𝒌 + 𝒕𝒊𝒎𝒆𝒐𝒖𝒕
Where
n= number of bit of position data
T= MA clock period
From the formula above, we can see that BiSS C cycle duration is not fixed but vary with number of bits of position data,
MA clock frequency used, ack duration and timeout duration.
Max Allowable BiSS C Cycle of Adapter [ IMPORTANT! ]
To ensure ITF-21-BISS-MIT function properly, the BiSS C cycle period should not exceed 102μs.
Basically, ITF-21-BISS-MIT can support any situation as long as the requirement of Max Allowable of BiSS C Cycle of
ITF-21-BISS-MIT of 102μs is adhered.
Calculation Example:
For n=12 bit, BiSS MA Clock Period=1MHz (1 μs), BiSS SLO ack = 35 μs, BiSS SLO Timeout=23.5 μs
BiSS C Cycle Period = (11.5 + 12) 1 μs + 35 μs +23.5 μs
= 82 μs
For n=32 bit (worse case than 26 bit), BiSS MA Clock Period=1MHz (1 μs), BiSS SLO ack = 35 μs, BiSS SLO
Timeout=23.5 μs
BiSS C Cycle Period = (11.5 + 32) 1 μs + 35 μs +23.5 μs
= 102 μs (equal to max allowable BiSS C Cycle Period of the adapter)

Mitsubishi Alarm No. 3 - BiSS SLO received by adapter violates BiSS C protocol rule (BiSS MA Rx Error) might be due
to the root causes below:
•Sync Error
Triggered if SLO is low during the first rising edge of MA clk
•Slave Ack Error
Triggered if SLO is high during the third falling edge of MA clk
•Start Bit Error
Triggered if SLO ack for more than max allowable acknowledge duration (35 μs)
•Zero Bit Error
Triggered if SLO is high after start bit
Mitsubishi Alarm No.4 - Mitsubishi RQ received by adapter violates Mitsubishi Serial protocol rule (Mit SL Rx Error)
might be due to the root causes below:
•Sync Code Error
Triggered if sync code received by adapter is incorrect
•Fake Start Error
Triggered if start bit detected does not hold low according to baud rate duration
The root causes of Mitsubishi Alarm no. 3 and 4 can be further diagnosed using PC software. Refer to diagnostic part of
PC software.
Troubleshooting for Mitsubishi Alarm
1. What will happen if driver is turned on without connected to ITF-21-BISS-MIT? Or 5V and Gnd of driver interface
cable is not connected correctly.
Answer: Mitsubishi Alarm 16.3 will be triggered.
2. What will happen if encoder is not connected to ITF-21-BISS-MIT? Or 5V and Gnd of encoder cable is not
connected correctly.
Answer: Mitsubishi alarm no. 3 (BiSS SLO received by adapter violates BiSS C protocol rule) will be triggered
due to Slave Ack Error. This is because since the encoder is not connected or power on, so there is no one pull
the SLO low to acknowledge the MA clk send by ITF-21-BISS-MIT.
3. What will happen if data lines between the driver and ITF-21-BISS-MIT is not connected correctly?
Answer: Mitsubishi Alarm 16.3 might be triggered.
4. What will happen if data lines between ITF-21-BISS-MIT and encoder is not connected correctly?
Answer: Mitsubishi alarm no.3 (BiSS SLO received by adapter violates BiSS C protocol rule) might be triggered.
