Desktop Switch Connects DB9 Interface With Four Devices
The Pathway Model 7385 DB-9 Interface A/B/C/D switch from Electro Standards Laboratories is a desktop network switch that allows the sharing of a single DB9 interface device among 4 other devices. Resistance between the common port pins and the corresponding current position pins is <0.8 O. With no local front panel controls, the switch is intended for “remote control only” applications. The DB9 remote port, located on the rear of the unit, accepts RS232 serial data ASCII commands for monitoring and control of switch position. All nine pins of the DB9 interface are switched and the switch ports are transparent to data format.
