Automatic Remote Control & Monitoring with Model 7259 DB25 Dual-Channel A/B Switch

Press Release:
  Apr 19, 2011 — Electro Standards Laboratories (ESL), Cranston, RI, has just introduced the PathWay® Model 7259 Dual Channel RS-530 A/B Switch, DB25 Interface with Exclusive Automatic Remote Control & Remote Monitoring. The Model 7259 allows the user two independent channels of AB switch function. The A/B function permits access of either of two devices connected to ports A and B, to a single port, the COMMON port.

This A/B data switch is exclusively controlled remotely from a device connected to its REMOTE port. The Remote port has a custom interface DB25 connector located on the rear of the unit. The various status, monitoring and control signals present on this port allow the switch to be managed by a device capable of interpreting these signals and, based on these signals, issue control commands to be executed by the switch. The switch position status is displayed on the front panel LED's

All (25) signal lines of the DB25 RS530 interface connector are supported. The switched ports are transparent to all data. Channels 1 & 2 are switched independently. The switch will monitor data and when the switch detects a loss of signal will provide a 1 second time delay before reporting to the external remote control device. Switches are latching and maintain their position during power loss. Switch data activity and position may be monitored via the Remote port. Switch provides data activity status from RD, pins 2 & 14 on the RS530 output of each channel as follows: activity present, send high signal; send low signal if no activity. Front panel LEDs display the current switch position and power status.
