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.
