When using an external 10Base5 (thick Ethernet) transceiver, the
AccessBuilder's LAN controller test will fail if the BNC interface is NOT
terminated. If this happens, be sure that a 50-ohm BNC termination resistor
is installed on each end of your cable run and reboot the system.
2 Install and connect your I/O card (or cards) to your modems, CSU/DSU, ISDN
line, etc. Refer to Appendix C for details.
3 (Console connection -- optional step) Connect a terminal or a PC running
terminal emulation (DTE) with a straight-through cable to the
AccessBuilder's console port (DCE). Default settings are 9600 Baudrate, 8
bits, 1 stop bit and no parity.
