Specifications of the CompoNet Communications Unit

Item Specification
I/O points Inputs: 32 bytes maximum (including status and areas which the Unit does not use)
Output: 32 bytes maximum (including areas which the Unit does not use)
Maximum number of SmartSlice I/O
Units
64 (Do not count the End Unit.)
Status area 1 word (This word shows the status of the CompoNet Communications Unit.)
Parameter backup and restore You can back up or restore a maximum of 2 KB of data for one CompoNet Communications Unit.
Baud rate The CompoNet Communications Unit uses the baud rate of the CompoNet Master Unit
(93. 75 kbps, 1.5 Mbps, 3 Mbps, or 4 Mbps).
Communications media You can use these cables:
Round Cable I (JIS C 3306, VCTF 2-core 0.75-mm2 twisted-pair cable)
Round Cable II (JIS C 3306, VCTF 4-core 0.75-mm2 twisted-pair cable)
Flat Cable I (without sheath, DCA4-4F10)
Note: The Round Cable I, Round Cable II and Flat Cable I are different types of cable. You must
use a Repeater to divide a branch line from the main line to use more than one type of cable.
Indicators MS (green/red): This indicator shows the status of the CompoNet Communications Unit.
NS (green/red): This indicator shows the communications status of the CompoNet network.
TS (green/red): This indicator shows the status of the SmartSlice I/O Terminal.
UNIT PWR (green): This indicator shows the status of the Unit power supply.
I/O PWR (green): This indicator shows the status of the I/O power supply.
Switches Rotary switches: There are two rotary switches. You use them to set the node address.
DIP switch: There is one DIP switch with four pins. You use them to set the operating mode.
Connectors There is one CompoNet communications connector.
