FOR IMMEDIATE RELEASE
Model 4143 RS232 DB25 Automatic Fallback A/B Switch
Electro Standards Laboratories (ESL), Cranston, RI, has just announced the Model 4143 RS232 DB25 A/B Automatic Fallback Switch. This DB25 Network Switch allows the sharing of a single device among two other devices, with front panel pushbutton control or remote control access.
All switched signals of Model 4143 are passed via latching copper contact relays that maintain their position and continuity even in the event of a power loss or failure. This network switch will automatically switch positions when a transition from 5VDC to 0VDC on Pin 9 of the DB25 Common port occurs. All 25 pins of the DB25 interface are switched and the switch ports are transparent to all data.
For more information about Electro Standards’ Network Switches or cables, call 401-943-1164, eslab@ElectroStandards.com, or www.ElectroStandards.com. All ESL products are available for export. Government Agencies contact Electro Standards for GSA pricing on COTS (Commercial-Off-The-Shelf) network switches.
