MASTER port is configured DTE and PORTS 1-3 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.
The total combined length of all cables connected to the unit should be less than 50 feet (15.2 m).
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.
Only one SLAVE port may transmit data to the MASTER port at any one time, Pin 2 on the three SLAVE ports are not tied in common and are isolated from each other by an OR gate
Use our Modem Splitter to connect three 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.
The TL073A-R4 includes (1) modem splitter, (1) 6-ft. DB25 male/DB25 female extension cable, and (1) serial DB9 female/DB25 male AT adapter.
pickup or postage $9.50 (Australia Wide)
