Chapter 3Using the Relay Multiplexer ModulesUsing This ChapterMultiplexer CommandsThis chapter uses typical examples to show how to use the 16-Channel Relayand 16-Channel Thermocouple Relay Multiplexer Modules. Refer toChapter 4 (“Understanding the Relay Multiplexer Modules”) for moreinformation. This chapter contains the following sections:• Multiplexer Commands. . . . . . . . . . . . . . . . . . . . . . . . . . . . . page 31• Connecting Switchbox Channels to Common . . . . . . . . . . . page 32• Connecting Switchbox Channels to Tree Terminals for MakingMeasurements . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . page 34• Scanning a Range of Switchbox Channels . . . . . . . . . . . . . . page 36• Measuring Temperature Using Thermocouples (HP E1344A/47AModules Only) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . page 39Table 3-1.

Connecting Switchbox Channels to Common• Closing any channel in Bank 0 (i.e., channels 00 to 07) connects thechannel to the Bank 0 Common.• Closing any channel in Bank 1 (i.e., channels 08 to 15) connects thechannel to the Bank 1 Common.Example: ConnectChannels 02 and 09 toCommonFigure 3-1 shows how to connect channels 02 and 09 of a single moduleswitchbox to their respective Common Terminals. Execute:CLOS (@102,109) 102 closes channel 02 and 109closes channel 09; the firstnumber (1) is the card number.Figure 3-1.
