The PathWay® Model 7120 Single Channel DB9 A/B Switch allows the user the capability of sharing a single DB9 device, connected to the “COMMON” port connector, among two other devices, connected to the “A” and “B” ports. The interface is made up of DB9 female port connectors. The Model 7120 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 locally by manually operating the front panel pushbutton or remotely using the Remote port on the rear. The Remote port allows the user to control switch position using TTL signaling or using a Remote Toggle Switch, (ESL Cable p/n 986479) connected to the DB9 (female) Interface Remote port located on the rear of the unit. The front panel LED display indicates the present position and unit power status. All connectors are switched simultaneously for a total of 9 pins switched.
FEATURES:
Allows quick connection to any one of two devices from one COMMON device.
The switch ports are transparent to all data.
All (9) pins of the DB9 interface are switched via break- before-make electromechanical relays.
The unit maintains last set position on power loss and continues to pass data.
Upon power up, unit can switch based on TTL or Contact Closure, or remain in the position it was in at power down.
Front panel pushbutton control.
The DB9 Remote port provides access to remotely switch the unit by dry contact open/close logic or from a toggle switch.
The DB9 Remote port allows the usage of TTL signals to switch the unit.
Front panel pushbutton lockout when Remote is in use.
Front panel LED’s display the present position and power status.
