Requirements for PC communication

A PC communicates with a FastRAD either through a modem or through an RS-232 cable. A modem is used when the PC is situated at a remote location. An RS-232 cable is used when the PC is situated near the FastRAD at the customer site.

When you use a PC at the customer site, you must use a 9-pin cable to connect the PC to the RS-232 port on the FastRAD. This connector is not supplied with the FastRAD. Table 1 shows which pins are used to make a connection with the FastRAD.

Note: The FastRAD modem supports V.32/V.32bis protocols only. We recommend a baud rate* of 9600 or greater be selected when connecting Norstar PC applications to the FastRAD remotely using a modem.

*Refers to the PC-Modem DTE speed.
