Chapter 1: Installation Backing Up the Disk The software supplied with the PCI-ICOM485/4 (/2) is provided on two 3.5-inch diskettes. As with any software package, you should make backup copies for everyday use and place your original master diskettes in a safe location. - Page 10 PCI-ICOM485/4 Manual ACCES95 and ACCESNT These two drivers are mentioned for users migrating from older versions of ACCES Tools. The functionality of ACCES95 and ACCESNT has been combined into ACCES32.DLL, which is described below. In order to modify your software to use the new ACCES32.DLL instead of the older code, change the file you link to from ACCES95 or ACCESNT to ACCES32.

Page 11: Installing The Card
Simple Communications TERMinal. Installing the Card The PCI-ICOM485/4 (/2) card can be installed in a five-Volt PCI slot of an IBM or compatible computer. Before installing the card, carefully read the Option Selection section of this manual and configure the card according to your requirements. Finally, our SETUP.EXE program will lead you through the process of setting the options on the PCI-ICOM485/4 (/2) card. - Page 12 PCI-ICOM485/4 Manual To install the card: 1. Turn OFF computer power. 2. Remove the computer cover. 3. Install jumpers from either the Option Selection section of this manual or the suggestions of our SETUP.EXE software program. 4. Install the card in an available PCI-bus slot.

Page 13: Input/Output Connections
Input/Output Connections The PCI-ICOM485/4 (/2) uses a 37-pin DBM connector. To connect to the serial device/s there will be the DB37 connector on the card and a “spider” cable providing two or four DB9 female connectors. To ensure that there is minimum susceptibility to EMI and minimum radiation, it is important that the card mounting bracket be properly screwed into place and that there be a positive chassis ground. - Page 14 PCI-ICOM485/4 Manual This page intentionally left blank Page 6 Manual Number: 00650-148-1...

32 devices on a single line. The number of devices served on a single line can be expanded by use of “repeaters”. The PCI-ICOM485/4 (/2) also has the capability to add load resistors to terminate the communica- tions lines. RS-485 communications require that one transmitter supply a bias voltage to ensure a known “zero”... -
Page 16: Baud Rate Ranges
In RS-485 communications, the driver must be enabled and disabled as needed, allowing all cards to share a two wire cable. The PCI-ICOM485/4 (/2) card controls the driver automatically. With automatic control, the driver is enabled when data is ready to be transmitted. The driver remains enabled for one additional character’s transmission time after data transfer is complete and then is... -

Chapter 3: Option Selection To help you locate the jumpers described in this section, refer to the Option Selection Map at the end of this section. Operation of the serial communications section is determined by jumper instal- lation as described in the following paragraphs. Terminations A transmission line should be terminated at the receiving end in its characteristic impedance.Installing a jumper at the locations labeled LDxO applies a 120W load across the transmit/receive input/... -

Bits 3 through 6 control parity and break enable. They are not commonly used for communications and should be set to zeroes. Bit 7 is the DLAB discussed earlier. It must be set to zero after the divisor is loaded or else there will be no communications. -
Page 26: Transmission
PCI-ICOM485/4 Manual Transmission RS-485 transmission is simple to implement. To transmit a string of data, the transmitter must first check Bit 5 of the Line Status Register at Base Address +5. That bit is the transmitter-holding-register-empty flag. If it is high, the transmitter has sent the data. The process of checking the bit until it goes high, followed by a write, is repeated until no data remains. -
