ETUP OF

Refer to Fig. 1 and locate the three Handshake Programming Jumper Pins on the

PC-HSICA board. A "minijumper" is provided for connecting either Pin 2 to Pin 3

or Pin 1 to Pin 2. Position the jumper for the desired handshake pair:

• To tie the UART's RTS (Ready to Send) output to Pin 20 of the RS-232-C

Interface Connector, connect jumper PINS 2 and 3. THIS IS THE DEFAULT

STATE.

• To tie the UART's DTR (Data Terminal Ready) output to Pin 20 of the RS-232-

C Interface Connector, connect jumper PINS 1 and 2.

2.a.2 M

As explained above, the PC-HSICA card can be set to either HSIC or 16C650

mode in order to accommodate the driver software being used ("16C650" opera-

tion requires serial driver software specific to the 16C650 UART). The mode of

operation is set by Switch 4 of the block of HSIC Programming Switches shown

in Fig. 1. This switch should be

• OPEN for HSIC mode (the default state); or

• CLOSED for 16C650 mode

NOTE: "HSIC" mode should normally be selected for operation with standard

BASIC drivers and Windows TERMINAL, and also when the PC-HSICA is being

used in conjunction with Daytronic StartPAC, SuperPAC, and related software.

2.a.3 B

Switches 1, 2, and 3 of the block of HSIC Programming Switches shown in Fig. 1

are used to set a specific combination of

• I/O REGISTER ADDRESS—the four possible values are 3F8-3FF (COM1),

2F8-2FF (COM2), 3E8-3EF (COM3), and 2E8-2EF (COM4)—and

• INTERRUPT REQUEST NUMBER—4 or 7 for COM1; 3 or 7 for COM2; 4 or 7

for COM3; 3 or 7 for COM4

Refer to the following table to determine the switch settings that correspond to

the desired combination of these parameters for your PC-HSICA card.

REMEMBER: CONFLICT BETWEEN THE PC-HSICA CARD AND A COM PORT

AND/OR INTERRUPT PRESENTLY IN USE IS NOT ALLOWED. FOR THIS REA-

SON, THE PC-HSICA MUST BE ASSIGNED A COM PORT NUMBER THAT DOES

NOT CORRESPOND TO A PRESENTLY ENABLED COM PORT, AND AN IRQ NUM-

BER THAT IS NOT ALREADY IN USE.
