Overview


Use Modem Splitter to connect six terminals to one modem and save money - you won't need extra modems and extra lines! No special cables are needed. It uses ordinary straight-pinned cables for a hookup, and includes a 6-ft. DB25 male/DB25 female extension cable and a serial DB9 female/DB25 male AT adapter.

The Modem Splitter is transparent to speed and protocol and works equally well in sync and async environments.
Features:

  • MASTER port is configured DTE and PORTS 1-6 are configured DCE
  • Signals present on the MASTER connector at pins 1, 3, 5, 6, 7, 8, 15, and 17 are sent to the corresponding pins on each of the PORT connectors.
  • Signals present on the PORT connectors at pins 2, 4, and 20 are passively stored and sent to the corresponding pins on the MASTER connector.
  • Data coming into the MASTER port on pin 3 of the RS232 DB25 Passive Splitter goes to all three Slave ports since they are all tied common.

Product Includes:

  • (1) Modem Splitter
  • (1) 6-ft. DB25 Male/DB25 Female Extension Cable
  • (1) Serial DB9 Female/DB25 Male AT Adapter
