ComBricks User Manual v6.4.0 | January 18| © PROCENTEC 39/219
3.11.1 Screw terminals
With a 1 channel repeater module, the channel is marked CH1.
With a 2 channel repeater module, the channels are marked CH1 and CH2.
NOTICE
Since March 2014 the 1 Channel, 2 Channel and Scope Repeater modules are fitted with new, more robust
screw terminals.
Old modules: The channels (CHx) have 2 screw terminals (IN and OUT, for the bus connection) and a
termination switch.
Always use the ‘IN’ connector when the repeater module is the first or last on the segment. The termination
should be set to ON (see Fig. 25 - configuration A).
New modules: The channels have 1 screw terminal and a termination switch. In most cases, the channel
starts here so the termination must be set to ‘ON’. If the channel is not the beginning, use the DB9
connector, see paragraph 3.11.2. Alternatively, use the dual ground clip (supplied with the new models) to
install two cables in one screw terminal, see Fig. 26.
Only in configuration A of Fig. 25 the on-board termination should be set to ON. In configurations B and D the
repeater module is in the middle of the segment (OFF).
Pin layout of the screw terminals
Pin “A”: Green wire
Pin “B”: Red wire
Pin “SH”: Cable shielding OR
Pin “I”: Cable shielding
