*1 These items can be set by software. For the "API Function Library API-PAC(W32)" and the
"Standard COM Driver Software COM Setup Disk" on the supplied CD-ROM, the range is 15 -
921,600 bps.
*2 Data transmission at high speed may not be performed normally depending on the environment
including the type of status of connected material of cable and environment.
*3 The table below lists an example of the relationship between baud rate and communication distance.
Communication
distance
Baud rate
300m 115,200bps
600m 57,600bps
900m 19,200bps
1200m 9,600bps
Communication cable: 28AWG, double shielded cable, twisted pairs used for each +/- signal line.
*4 A single interrupt signal "INTA" is output as a collection of interrupt input signals from two
channels.
*5 This board requires power supply at +5 V from an expansion slot (it does not work on a machine
with a +3.3V power supply alone).
*6 If the board No. is 7195, PCI bus specification is 32bit, 33MHz, 5V.
*7 If the board No. is 7195, Dimension is 121.69(L) x 106.68(H).
