Figure 3.42 SCP/A Connection Example
Connecting the NK-SCP/K2
The NK-SCP/K2 is connected to the Geneos CPU with the parallel to serial converter cable supplied (Part number
9801 2001). If the NK-SCP/K2 and NK routers have been purchased as an addition to a preexisting Kondor 2 and
Geneos CPU system, this cable would have been supplied with the initial Kondor 2 / Geneos shipment.
The NK-SCP is phantom powered by the T-Bus, allowing the heartbeat to show communication activity when
messages are sent from the Geneos CPU.
Figure 3.43 SCP/K2 Connection Example
Parallel to Serial Converter
The Parallel to Serial converter is housed inside the DB-37 connector shell which plugs into the Parallel Output
Control connector located at the bottom left side at the rear of the Geneos CPU frame. Power to the converter is
supplied via the DB-25 connector (wired to the DB-37). The DB-25 connector plugs into the AUX connector
located at the bottom left side at the rear of CPU frame. The Serial output from the converter is available from the
DB-9 plug (wired to the DB-37), this DB-9 plugs into the top RS-485 DB-9 on the Rear left of the Kondor 2 frame.
The PC communications cable is wired to the DB-25, the PC end has both a DB-25 and a DB-9 for connection to an
RS-232 communications connector on a PC running Geneos.
