RS-232

RS-232 PRODUCTS


(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.
