Please step through each of the options which pertain to your card to insure that your card is configured as you desire. / Configuration options for the PCOM2S include: Echo Option Auto RTS Option Termination RS-232/RS-422/RS-485 communication protocol ][ THelpTopic# Options Echo The PCOM2S allows you to select whether the card leaves the receive line on. This means that every character that is transmitted is also received by the port (i.e. echoed back). In RS-232 mode, this is automatic, so it would be redundant to install the jumper when in that mode. ][ THelpTopic+ Options Auto RTS kThe PCOM2S allows you to select whether the card will control the RTS line through hardware or not. On standard RS422/485 cards, software must control the Ready To Send (RTS) line in order to specify whether the software will be transmitting data or listening for it. The PCOM2S will automatically set and clear this line for you when this jumper is installed. ][ THelpTopic; Options Port Termination /The PCOM2S allows termination where necessary. ][ THelpTopicG Options Communication Protocol The PCOM2S allows you to select whether the card will use the RS-232 protocol, the RS-422 protocol, or the RS-485 protocol. RS-232 is what is found in most Personal Computers. It is the type of connection that serial ports in PCs use. There are limitations to this specification, so the RS-422 protocol was defined. This type of connection allows longer distances, but is also limited to a two node connection. RS-485 allows multiple nodes, and is a two-wire connection, making it very flexible. ][ THelpTopic# Options BIAS `The PCOM2S allows selection of a -BIAS and +BIAS. This allows a greater pull-down and pull-up. ][ THelpTopic= Options PCI Configuration This dialog shows you the current base addresses for both COMA and COMB of the PCOM2S.
