5.4 Wire Connection

Figure 5: Connection diagram

5.4.1 Analog output

There are 3 models available: 0 to 5 V, TCJ, TCK.
Minimum load impedance for 0 to 5 V output should be 50 kΩ.
Inner impedance of TC output circuit is 100 Ω.

5.4.2 Alarm output

RS232 TxD and alarm output share one single wire. Either can be selected by
the DataTemp software or RS232 command. When alarm mode is active, the
CM can receive command from a PC via RS232, but can't respond to the PC.
RS232 TxD can work normally after the alarm output is switched off by
command K=0, see Section 10.3 Command Set. If unit is set by DataTemp
software, alarm output is valid only after the unit is restarted.
