10 Chapter 3 EIA-232 Asynchronous Interface

• In situations where low-capacitance cable is unavailable, or very

long cable runs are required, "short-haul" modems can be used to

increase the effective range of the EIA-232 interface. Short-haul

modems are similar to standard modems, except that they are

connected directly to each other via a cable instead of going through

a telephone circuit.

• Use only externally-powered short-haul modems with Digi products.

Transmission Errors

If transmission errors occur, follow this procedure to determine the cause of

the problem:

1. Reduce the baud rate.

2. Reduce the cable length.

3. Use a cable with a lower capacitance per foot rating.
