3 Keyboard Models
The LTC 8555 Series keyboards are available in four models. The table below summarizes the
differences between models:
The LTC 8555/00 and LTC 8555/01 models use the Allegiant RS-485 communication protocol,
and are the most common versions. These models are ready to operate as soon as they’re
connected to the Allegiant system.
The LTC 8555/02 and LTC 8555/03 are similar, but use an RS-232 communication protocol.
These models can be used with communication links that support full duplex RS-232
transmission. Since the RS-232 models connect to the Allegiant’s RS-232 ports rather than
the standard RS-485 keyboard ports, some initial configuration programming of the Allegiant
switcher is necessary. With a few minor exceptions, general operation is identical for all
models.
Although the LTC 8555/00 and LTC 8555/01 are compatible with Allegiant systems of any age,
the LTC 8555/02 and LTC 8555/03 models require Allegiant CPU firmware version 7.6 or
higher. Although this version was released in late 1998, it is possible to update older systems
using a firmware download in some cases or by replacement of the CPU module with a
current version. If necessary, contact your local sales office for additional details.
