RS-485 Directional Control

Many device drivers use the RTS signal to switch between receive and transmit mode. Some third party communication drivers expect the directional control to be automatic. The PA PowerStation does not automatically switch between modes and depends on the driver to use the RTS signal to perform this operation.

Transferring Files from a PC to the PA PowerStation

You can transfer files from a PC to the PA PowerStation in one of three ways—through the Ethernet, the CompactFlash, or a Serial Transfer. If you plan to use a Serial Transfer, you will need a null modem cable. To construct your own cables, refer to Figure 3-7,for the appropriate settings, then continue with step 1 below.
