8Optional Accessories Installation
8.1 General Accessory Installation
There are many accessory products available for the Allegiant Series, including key-
boards, alarm interface units, control code signal distribution units, etc. If applicable,
these products can be installed at the same time as the main CPU bay installation,
or postponed until later. In some cases, products are designed to be racked in close
proximity to the main CPU bay, so appropriate rack space should be reserved.
Please refer to the instructions supplied with the specific accessory product for com-
plete installation details.

NOTE The required interconnect cable utilizes a custom pinout. Refer to the Appendix

nector on the printer.

nector marked “PRINTER”.
