The CIO-CTR BASE switch may be set for address in the range of 000-3F8 (000-3FC
for the CIO-CTR05) so it should not be hard to find a free address area for your CIO-
CTR. Once again, if you are not using IBM prototyping cards or some other board
which occupies these addresses, then 300-31F HEX are free to use.

Address not specifically listed, such as 390-39F, are usually free.
INTERRUPT LEVEL SELECT
There are two rows of jumper blocks on the CIO-CTR10 and one on the CIO-CTR05,
located just above the PC bus interface (gold pins). The factory default setting is that
no interrupt level is set. The jumper is in the 'X' position.

no interrupt level is set. The jumper is in the 'X' position.
Please leave the jumper in the 'X' position for now. Interrupts are hardware initiated
software routines and are discussed in the section on programming.

On the CIO-CTR10 the lower block,
J2, is for the IR input on P1. The
upper block, J3, is for the IR input

The trigger logic on the CIO-CTR is
quite simple. Pin 1 of the 37 pin
connector is an input jumper which
maps the interrupt directly onto the
PC bus. The signal to the bus is
buffered. The buffer is enabled by a
TTL low level on Pin 2, interrupt
enable.

The interrupt level jumper on the
CIO-CTR must also be installed.
Move it from the 'X' position to the
IRQ number you want the interrupt pulse on. On the CTR10, jumper block J2 is asso-
ciated with the signals on connector P1. Jumper block J3 is associated with the sig-
nals on connector P2.
