Configuring Online Communication
This chapter describes online communication between the HHT and SLC 500
processors. Topics include:
• online configuration
• the Who function
As described in chapter 1, the HHT may be connected directly to a port
located on an SLC 500 processor or it may be connected to any fixed, SLC
5/01, or SLC 5/02 processor that is active on a DH–485 network.
Important: The HHT is not compatible with the SLC 5/03 processor.
For the examples in this section, the DH–485 network is configured as
follows:

0 APS Terminal
1 Hand–Held Terminal
2 SLC 5/02 Processor
3 SLC 500 Processor
