(Synchronous and Asynchronous)
The RS-232 SHARING PRODUCTS (MODEM SHARING, PORT SHARING, and CABLING HUBS) are normally used on polled main frame type networks where the terminals or a cluster controller have unique device address.
The SIGNAL BOOSTERS, SIGNAL CONVERTERS, and SHORT RANGE MODEMS may be used on any RS-232 line.
Note that not all of the following products support all of the RS-232 signals. When making your selection it is important to determine if your requirement is for Synchronous or Asynchronous transmission and how many of the RS-232 control signals are required. To help you make your selection, a small application chart accompanies each product.
Modem Sharing Products
These products allow multiple addressable terminals to share a single modem. They are normally used at a remote location, but can also be used at the host site using a null modem cable.
RS-232 Signal Boosters
These products can be used in the middle of a RS-232 cable run to regenerate the RS-232 signals. They can also be used in pairs similar to short range modems, except that the signal is not converted between them.
RS-232 Signal Converters
These products convert the RS-232 signal to another signal discipline such an RS-422, fiber optic, USB, etc. The converted signal can be used by another device with a compatible interface or the products can be used in pairs, as Short Haul Modems to operate over longer distances. The second unit re-converts the signal back to RS-232.

This asynchronous RS-232 to Fiber Optic converter is built in a DB-25 gender mender sized enclosure. It can be used as a stand alone unit connected directly to the RS-232 port of a terminal, PC, modem, or mux. Learn More
Cable Distances Up To 2000' Per Port.Eight port sharing unit. LEDs define RTS and receive data on all ports. LEDs on the Host port addresses additional signals. One DB-25 Male DTE and eight DB-25 female DCE connectors. Cable distances up to 2000' from each port. Return signal booster may be required at each terminal where cable distance exceeds 150'.

This is a convenient low cost sharing unit with two female DB-25 terminal connectors and one male DTE connector. It is designed to connect to the terminal and provide a "down stream" port in a daisy chain fashion. Up to four units can be used in a daisy chain. The total combined cable distance should not exceed 150' at 9600 bps and 100' or less at 19.2 KB. Learn More
