Low Impedance and Remote Control Now Available in a DB9 ABCD Network Switch

Oct. 5, 2011 - PRLog -- Electro Standards Laboratories (ESL), Cranston, RI, has just announced its new PathWay® Model 7385 DB-9 A/B/C/D low impedance switch with exclusive remote control. The Model 7385 allows sharing a single DB9 interface device connected to the Common port among four other devices connected to the A, B, C and D ports. All five port connectors are DB9 Female. This switch is housed in an attractive aluminum packaging that provides EMI/RFI shielding. The desktop configuration has dimensions of 2.4” H x 8.0” W x 7.25” D. The switch weighs approximately 4.5 lbs.

There is no local or front-panel switch control on this switch. The Model 7385 can only be switched remotely from the DB9 female RS232 serial interface remote port. This port accepts RS232 Serial data ASCII commands for switch position control and monitoring. The front-panel LED display indicates the switch position and unit power status. Four LED’s labeled A, B, C and D display the switch position. One LED labeled Power displays the power status. The switch maintains its last set switch position in the event of a power loss and continues to pass data.

For applications where low impedance is important this switch is ideal. The resistance between the COMMON port pins and the corresponding current position pins is less than 0.8 ohms. The switch ports are transparent to data format. All 9 pins of the DB9 interface are switched making this switch applicable to any DB9 device. The switch comes complete with a UL approved wall mount 110/120VAC, 60Hz power module that supplies 12VAC, 500 mA to the switch.
