PathWay® Model 4481 Remotely Controllable DB25 RS232 8-Way Switch
Overview
The PathWay® Model 4481 Remotely Controllable DB25 RS232 8-Way Switch allows the user the capability of sharing a single port interface device connected to the “COMMON” port among eight other devices connected to the “A”, “B”, “C”, “D”, “E”, “F”, “G” and “H” ports. The Model 4481 is enclosed in a 1U, full rack size, all metal, black chassis designed to provide EMI/RFI shielding and fit in a standard 19” rack.
The switch may be controlled remotely from a device connected to the DB25 Female COMMON port located on the rear of the unit via Selectable Trigger Characters or a distant device via modem connection. Switch position states may be attained locally via the front panel LED display or remotely using ASCII Code Protocol.
