6.10.7. Multidrop RS-232 Set Up

The RS-232 multidrop consists of a printed circuit assembly that plugs onto the CN3, CN4, and CN5

connectors of the CPU card (see Figure 6-9) and the cabling to connect it to the analyzer’s
motherboard. This PCA includes all circuitry required to enable your analyzer for multidrop
operation. It converts the instrument’s COM1 port to multidrop configuration allowing up to eight

analyzers to be connected the same I/O port of the host computer.

Because both of the DB9 connectors on the analyzer’s back panel are needed to construct the

multidrop chain, COM2 is no longer available for separate RS-232 or RS-485 operation, however,
with the addition of an Ethernet Option (option 63, see Sections 5.6.3 and 10.6.6) the COM2 port is

available for communication over a 10BaseT LAN.
