"Alarm 2" relay on the rear panel. This allows you to have multiple alarm levels
for individual gases.
A more likely configuration for this would be to put one gas on the "Alarm 1"
relay & the other gas on the "Alarm 2" relay.

LARM ELAY
This relay is connected to the "range bit". If the instrument is configured for "Auto
Range" & the instrument goes up into the high range, it will turn this relay on.
The T-Series analyzers are equipped with connectors for remote communications
interfaces: Ethernet, USB, RS-232, optional RS-232 Multidrop, and optional RS-
485. In addition to using the appropriate cables (Table 1-1 describes the cable
options, 60A through 60D), each type of communication method must be
configured using the SETUP>COMM menu (Section 5.7).

THERNET ONNECTION
For network or Internet communication with the analyzer, connect an Ethernet
cable from the analyzer's rear panel Ethernet interface connector to an Ethernet
port.
Configuration: Section 6.3
USB O C
PTION ONNECTION
For direct communication between the analyzer and a personal computer (PC),
connect a USB cable between the analyzer and desktop or laptop USB ports. (If
this option is installed, the COM2 port can only be used for RS232 multidrop
communication). USB driver download is required.
Configuration: Section 6.4
RS-232 C
ONNECTION
For RS-232 communications with data terminal equipment (DTE) or with data
communication equipment (DCE) connect the applicable cable option (Table 1-1:
either a DB9-female-to-DB25-male cable, Option 60A, or a DB9-female-to-DB9-
female cable, Option 60B) from the analyzer's rear panel RS-232 port to the
device. Adjust the DCE-DTE switch (Figure 3-4) to select DTE or DCE as
appropriate.
Configuration: Section 6.1 (and Section 6.5.2 for Hessen protocol).
