INTRODUCTION
The 8PK-SCS is a serial switching system, capable of providing several functions:
Port Selector
As a port selector, the 8PK-SCS allows one Master RS-232 asynchronous channel to be selectively
switched to any of up to 8 ports. As a Port Selector, the 8PK-SCS can be used to provide access from
one modem or terminal to multiple systems. A typical use for the Port Selector is to access out-of-band
management ports on multiple devices. By using simple escape strings or easy to use menu
commands, the operator can select which port to access. Ports can also access the Master by raising a
control lead. While accessing a port, the 8PK-SCS is passive, allowing all data to pass until it receives
a user programmable command.
Relay Controller
As a relay controller, the 8PK-SCS accepts code or menu commands from its Master Port to energize or
de-energize eight relays. These relays can be used, in turn, to control any device that responds to a
contact closure or open. When connected to Dataprobe supplied A/C or D/C power switches,
communications A/B switches or other devices, the 8PK-SCS allows remote control of many systems
through its Master RS-232 port.
