When Repeater Units are connected in series Repeater Unit application conditions from the Master Unit, up to 2 extra segment layers can be created (i.e., up to 2 Repeater Units are allowed between a Slave Unit and the Master Unit). Signal lines Two lines: BDH (communications data high) and BDL (communications data low) Power lines Two lines: BS+ and BS− (power for communications and internal Slave Unit circuits) • Power is supplied from the Master Unit or Repeater Units. Communications power supply 24 VDC ±10% Connection forms Flat Cable at baud rate of 93.75 kbps: No restrictions Other cables or baud rates: Trunk line and branch lines Connections for Slave Units and Repeater Units: T-branch or multidrop connections *1. FINS message communications are supported by CJ-series Controllers only. *2. Drop-line connections are not supported with a baud rate of 4 Mbps, so Slaves with prewired cables (Bit Slaves) cannot be used. *3. Round cable, Flat Cable, and Flat Cable II are all different types of cable. To use more than one type of cable at a time, Repeater Units must be used to separate them on trunk lines and sub-trunk lines. 2 CJ1W-CRM21 Cable Types, Baud Rates, and Maximum Distances This section provides specifications on the maximum cable length and maximum number of nodes for each type of cable.
