Page 27: Terminations And Bias
Terminations and Bias ä ä ä ä A transmission line should be terminated at the receiving end in its characteristic impedance. Installing a jumper at the location labeled TRMO applies a 120_ load in series with a 0.01µF capacitor across the output (if desired) for RS422 mode and across the transmit/receive output/ input for RS485 operation. -

Full or Half-Duplex ä ä ä ä Full-Duplex allows simultaneous bi-directional communications. Half-Duplex allows bi-directional transmit and receiver communication but only one at a time, and is required for RS485 communications. Proper selection depends on the wire connections used to connect the two serial ports. -

Address Selection ä ä ä ä The 104-422/485-2I base address can be selected anywhere within the I/O bus address range 000-3E0 hex, providing that the address does not overlap with other functions. If in doubt, refer to the table below for a list of standard address assignments. (The primary and secondary binary synchronous communication ports are supported by the Operating System.) The base address locator program FINDBASE provided on CD (or diskettes) will assist you to select a base address that will avoid conflict with other installed computer resources. - Page 31 Hex Range Usage 300-31F Prototype Card 360-36F Reserved 378-37F Parallel Printer Port 1 380-38F SDLC or Binary Synchronous Comm’n 2 3A0-3AF Binary Synchronous Comm’n 1 3B0-3BF Monochrome Display/Printer 3C0-3CE Local Area Network 3D0-3DF Color/Graphic Monitor 3F0-3F7 Floppy Diskette Controller 3F8-3FF Asynchronous Comm’n (Primary) Card Address jumpers are marked A5-A9.

Page 50: Reception
The third step of the initialization sequence is to set the Modem Control Register at Base Address +4. This register controls functions on some cards. Bit 1 is the Request to Send (RTS) control bit. This bit should be left low until transmission time. (Note: When operating in the automatic RS485 mode, the state of this bit is not significant.) Bits 2 and 3 are user-designated outputs. -

The handler would first read the Interrupt Identification Register at Base Address +2. If the interrupt is for Received Data Available, the handler then reads the data. If no interrupt is pending, control exits the routine.
