5.1.4 Termination

The router will need to be terminated only if it is an 

endpoint of a daisy-chain segment. If the router is not at an 
endpoint (i.e. both the INCOMING and OUTGOING ter-
minals on one side of the router both have devices con-
nected to them), you do not need to terminate at the router.

  The router does not have on-board termination jump-

ers to use for termination. Therefore, the router will have 

to be terminated using Daisy Chain Termination Blocks 
(P/N 535-2715). To terminate a segment, wire the end of 
the segment wire to the screw terminals on one end of the 
termination block. Using a short length of Echelon cable, 
connect the INCOMING router terminals (terminals 1 
and 2
 on side A, terminals 17 and 18 on side B) to the 
termination block. Connect the shield wire from the center 
terminal of the Daisy Chain Termination Block to termi-
nal 5.
 See Figure 5-2.

  

  

 

Wire this repeater using appropriate NEC wiring meth-

ods. Use CL2P type wiring.

If the repeater is placed in between nodes in the system 

(see Figure 5-3), the wiring hook up is as follows:

1.

Locate the Echelon terminals on the repeater (see 
Figure 5-3). Note that there are two pairs of ter-
minals; top and bottom. 

2.

Connect the incoming three conductor wire to 
either one of the top jacks and the outgoing wire 
to one of the bottom jacks. Follow the diagram in 
Figure 5-3.

3.

If the segment from where the incoming wire is 
to be terminated, terminate the jumpers associ-
ated with the top pair of jacks (J7, J8 jumped in 
the up position), and likewise, if the segment fol-
lowing the repeater is to be terminated, terminate 
those jumpers (J1 and J4).

4.

External repeaters require a UL Class 2, 24VAC, 
minimum 0.1 Amp transformer (P/N 640-0041, 
110V and 640-0042, 220V). Connect the wiring
