4. INSTALLATION
4.1. HARDWARE INSTALLATION
CAUTION
Turn off the power before removing or installing VMEbus boards. Removing or reinstalling the boards while the power is on
will damage the boards.
This section describes the physical installation of the BCU/CAL. Other configuration is performed during manufacture,
and the information necessary is provided in Appendix B.
Follow these steps to connect a BCU/CAL to an IMC for the first time (except where indicated otherwise, these steps
apply to all configurations; BCU only, CAL only, or BCU and CAL):
Using the LAPB cable provided, connect the BCU/CAL's CAM control port 0, a female DB-25 connector located on the
rear of the BCU enclosure, to the lower connector on the IMC backplane which corresponds to the slot in which the CAM
resides. The cable is keyed so that it fits properly only when it is correctly oriented.

Next, connect the console terminal to the female DB-25 connector labeled "SERIAL PORT 1/CONSOLE" on the
TVME-712/M transition module located in the rear of the BCU/CAL enclosure. (For reference, the BCU/CAL is delivered
preconfigured from the factory in a 19-inch rack.) Connect the other end of this cable to the console terminal's "host" port, or
equivalent. If a PC is used as the console terminal, then a DB-9 adapter may be needed. In either case, the serial cable for the
console is wired straight-through.
Configure the console terminal for the communications parameters below.
• 9600 Baud
• No Parity
• 8 Data Bits
• 1 Stop Bit
