interconnect subsequent shelves. Each shelf controller should be assigned unique sequential shelf addresses. No connection should be made to the RS422 in connector on the shelf containing the E220 HCOT-CTL.

4. FACEPLATE FEATURES

The terminal interface operates at a data rate range of

4.8kbps to 19.2 kbps. The asynchronous data format is fixed at eight data bits, no parity, one stop bit. The supported terminal type is VT 100, or compatible.

Optional terminal parameters should be set as follows:

Table 6 defines the faceplate features of the HFAC.

5. CONTROL PORT OPERATION

The HFAC provides a faceplate-mounted DB9 connector which supplies an RS232 interface for connecting to a controlling terminal. Pin assignments are shown in Figure 6.

alarm is silenced. The condition of the alarm itself is not affected.

 

 

 

 

 

Fuse

This 0.25 -amp fuse is provided to protect the card from power-related

 

 

 

failures. The fuse is a BUSS BMT-0.25, or equivalent. If the fuse opens, a

 

 

 

fuse alarm is generated as described in subsection 2. The fuse has a visual

 

 

 

tripped indicators. When the metal tab (visible through the cover) flips up,

 

 

 

the fuse has opened.

 

 

RS232

A faceplate-mounted DB9 connector which supplies an RS232 interface

 

 

 

for connection to a controlling terminal. Refer to subsection 5.
