2.5 Jumper and DIP Switch Description
You can configure the output of each channel and base address
by setting jumpers and DIP switches on the PM-7841. The card's
jumpers and switches are preset at the factory. Under normal cir-
cumstances, you should not need to change the jumper settings.
A jumper switch is closed (sometimes referred to as "shorted")
with the plastic cap inserted over two pins of the jumper. A jumper
is open with the plastic cap inserted over one or no pin(s) of the
jumper.
2.6 Base Address Setting
The PM-7841 requires 16 consecutive address locations in I/O
address space. The base address of the PM-7841 is restricted by
the following conditions.
1. The base address must be within the range 200hex to
3F0hex.
2. The base address should not conflict with any PC
reserved I/O address.
The PM-7841's I/O port base address is selectable by an 5 posi-
tion DIP switch SW1 ( refer to Table 2.1). The address settings for
I/O port from Hex 200 to Hex 3F0 is described in Table 2.2 below.
The default base address of your PM-7841 is set to hex 200 in the
factory( see Figure below).
