Registers
The AR-B2103 occupies 4 consecutive addresses in the PC I/O space of which only two actually used. The base or
starting address is selected during the installation procedure.

When the output is energized, the status LED indicator will light up to indicate an active input.

Note that all port are 8 bit (one byte) wide and require byte oriented write operations rather than work operations.
All relays in a port are updated simultaneously. Writing a low (0) to a relay within a port deactivates the relay.
Writing a high (1) to a relay activates it.
Programming
Registers
No driver is supplied with the AR-B2103 since the program is very simple and can be accomplished most efficiently
using direct I/O instructions, in whatever application language is used (i.e., Basic, C, Assembly, Pascal, etc.). For
example, assume that one wishes to turn on relay channel 7. Also assume the AR-B2103 board has been set to base
address 992(3E0 hex). To turn on relay channel 7, one simply writes 01000000 to base address 992. Likewise to turn
on channel 10, 12 and 14 one writes 42 decimal (00101010 binary or 2A hex) to I/O address 993(3 E1 hex).The
following example is the BASIC language but it can be easily been translated to other languages. Example:
Assume the AR-B2103 is installed at base address 992(3E0 hex).
To turn on the channel 1 and 10, write as follows:
1000BASE_PORT = &H3E0: REM Base I/O addresses
1010 OUT BASE_PORT, 1: REM Turns channel 1 ON
1020 OUT BASE_PORT+1,2: REM Turns channel 10 ON
To control the desired relays but make no effect to other relays, write as follows:
2000 BASE_PORT = &H3E0 : REM Base I/O addresses
2010 PORT1 = (INP (BASE_PORT) OR1): REM Read back port 1 status and set bit of channel 1
