2-1-3 CompoNet Communications Specifications
* Lengths given in parentheses are for when two Repeater Units are used.
Item Specification
Communications protocol CompoNet protocol
Baud rate 93.75 kbps, 1.5 Mbps, 3 Mbps, or 4 Mbps*1
*1
A baud rate of 4 Mbps is not supported for branch lines and thus cannot be used for
Slave Units with Cables.
Modulation Baseband
Coding Manchester code
Error control Manchester code rules, CRC
Communications media Round Cable I (2-conductor cable, JIS C3306)
Round Cable II (4-conductor cable, JIS C3306)

Maximum I/O capacity Word Slave Units: 1,024 inputs and 1,024 outputs (2,048 I/O points total)
Bit Slave Units: 256 inputs and 256 outputs (512 I/O points total)
When the Gateway Unit is used, I/O capacities are as follows depending on the CompoNet
communications mode.
Max. number of connected
nodes Word Slave Units: 64 input nodes and 64 output nodes
Bit Slave Units: 128 input nodes and 128 output nodes
When the Gateway Unit is used, the maximum number of connected nodes is as follows
depending on the CompoNet communications mode.
