GE GFK0579B User Manual

Series 90–70 Remote I/O Scanner User’s Manual – July 1992

Set Up the Hand–held Monitor

If the remote drop is connected to an operating bus, the Hand–held Monitor
must be the ONLY Hand–held Monitor plugged into any device on the bus.

If the remote drop that is NOT connected to a properly–terminated Genius bus,
install a 150

terminating resistor across the upper Serial 1 and Serial 2 terminals

on the Remote I/O Scanner. The resistor is needed only for off–line
communications between the HHM and the Remote I/O Scanner; it should be
removed prior to bus installation.

Begin with the HHM turned off. Attach it to the upper port on the Remote I/O
Scanner.

MONITOR

Turn the Hand–held Monitor on. Adjust its baud rate if necessary.

Previously unconfigured Remote I/O Scanners will operate at 153.6 Kbaud
standard. You should be aware of the operating baud rate before trying to
communicate with the Remote I/O Scanner, and the Hand–held Monitor’s baud
rate should be set correspondingly.

After the Hand–held Monitor completes its powerup sequence, the Home menu
appears.

Be sure the HHM is set up for the type of host that will be controlling the system.

If necessary, go to the HHM Utilities to select the CPU host type.

If the message

FUNCTION DISABLED

appears, the corresponding HHM option has

been disabled. To continue, it will be necessary to change HHM options in the HHM
Utilities menu. If the message

CONFIG PROTECTED

appears, the Remote I/O Scanner

configuration has been protected. To continue, it will be necessary to “unprotect” the
remote drop’s configuration.
