RTS / DTR Selection
Jumpers JP1 through JP4 allows selection of RTS (default) or DTR as the control lead used for Lead
Control. To access these jumpers, disconnect the power source and remove the top cover of the
8PK-SCS. See Figure 4 for location of jumpers.
Control Relay Connection
Connection to the eight control relays are made using eight RJ11 modular jacks located internally on
the printed circuit board. To access these connections, disconnect the power and remove the top cover
of the unit. (Refer to figure 4, component location) Dataprobe supplies A/C power and communications
switches that can be used with the 8PK-SCS. The pin-outs of the modular jacks are designed to
connect directly to Dataprobe’s relay switches. In some cases a control cable, available from Dataprobe
is required.
