8.2.2 Initial Observations
1. On each Hydran 201Ci-C, verify the Supervisory Link Supply indicator (green,
DS12; item 15 in Figure 4-3) is lit.
2. On each Hydran 201Ci-C, look at the Heater indicator (yellow, DS8; item 13 in
Figure 4-3):
• The LED must initially be lit if the ambient temperature is below approximately
25°C (77°F).
• After a while, the LED must flash as the enclosure temperature reaches the
above set point.
• The LED must remain off if the ambient temperature exceeds the set point.
8.2.3 Verification of RS-232 or USB and RS-485 Communications
If your installation includes only one Hydran 201i System and if it communicates with
the host computer running the Hydran Host or Perception software, you must verify the
RS-485 to USB converter or RS-232 link or USB link depending of which one is used. If
your installation includes several Hydran 201i Systems forming a local RS-485 network,
you must also verify the RS-485 local network link. Proceed as follows:
1. Put all Hydran Ci-Cs in a common network by connecting the RS-485 LAN cable
from one H201Ci-C's RS-485 LAN connector (J11; item 11 in Figure 4-3) to the next
in a daisy-chain fashion. Refer to Chapter 10
2. Ensure all Hydran 201Ti's and all H201Ci-C's are connected together.
3. If Hydran Ci-C needs to be connected to the host computer: connect the DB-9
male RS-232 connector (item 2 in Figure 4-2 or J10; item 7 in Figure 4-3) or the
female USB connector (item 3 in Figure 4-2 or J16; item 8 in Figure 4-3) of any
H201Ci-C on the network to your PC's RS-232 port or USB port. For wiring details,
see Table D - 7.
4. In the Communication submenu of each H201Ti, write down the current settings,
in order to be able to restore them.
5. Set the parameters as follows:
• Comm Channel = Supervisory Link
• DefaultChannel = Supervisory Link
• Baud Rate = 9600
• Gas Monitor ID = 1
CAUTION
Page 124
At least one H201Ti in a local network must be set with an
identification number (Gas Monitor ID) from 1 to 5 inclusively.
Each H201Ti in a local network must have an exclusive number
from 1 to 254. The H201Tis are normally shipped with the Gas
Monitor ID number set to 1.
