Expansion Hardware allows the addition of more APUs (Asynchronous
Port Units) to your Alpha Micro system. Products are designed for the
AM-2000M, AM-1500, AM-2000 and AM-3000. The number of ports can be
affordably increased from 32 to 256 with the APU I/O Board.

 APU
Serial IO Board
Compatibility:
Get the most out of your Alpha Micro computer system with Macrotech's
APU IO Board. This 16 port Serial I/O Card allows you to install up to
256 ports on any VME CPU, the AM-2000 CPU or the VIP2. It can also be
run on the AM-350, limited to the number of ports as the AM-358 (32
ports per cable). Up to 16 APU cards can be connected to the AM-2000M,
AM-1500, AM-2000 or the AM-3000 without using the AM350.
Serviceability:
Both RS-232 and RS-422 chips are socketed for ease of service. Ejectors
on cable connector allow for easy cable removal. To install, simply dial
the rotary switch to the correct board number, define the terminal, plug
it in and your job is complete.
Expandability, Internal Addressing:
Up to 256 ports (16 APUs) can be plugged into an I/O cable. The I/O bus
has 16 logical locations. Since each APU uses one, and each AM-355 uses
3 and each AM-358 uses 4 address locations, the following formula can be
used to calculate the total number of APUs that can be added to any I/O
cable:
# APUs = 16 - ( 3 x AM355) - (4 x AM358),
where AM355 is the number of AM-355s and AM358 is the number of AM-358s
on the cable. Note that removing one AM-355 frees up space for 3 APUs.
