Black Box TL074A-R4 RS232 Passive Splitter, DB25 (F), 6-Port

Use the TL074A-R4 Modem Splitter to connect six terminals to one modem and save money - you won't need extra modems and extra lines! The Modem Splitter allows an RS-232-C DCE device, such as a modem, to interface with up to six RS-232-C DTE devices, such as terminals. The MASTER port is configured DTE and PORTS 1 - 6 are configured DCE. No jumpers and/or switches are located on the Modem Splitter. 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.

Key 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
  • 1 Year Double Diamond™ Warranty (Standard) included. Extended warranty available. Contact Westward Sales.
