3.2.2.3 Configuring the Switches on the Outstation PCB
Before any connectors are attached to the Outstation PCB, the configuration
switches need to be set up as described below. Refer to Figure 18 or Figure 19 for
the position of the switches on the PCB.
There are four switches on the PCB.
S2 = Lithium Battery On / Off Switch
switches need to be set up as described below. Refer to Figure 18 or Figure 19 for
the position of the switches on the PCB.
There are four switches on the PCB.
S2 = Lithium Battery On / Off Switch
S3 = Line Level Switch
S4 = 2 / 4 Wire Select Switch
S6 = 600
Ω / High Impedance Switch
These are set as follows:
1. Slide the PCB out of the card guides.
2. S2 - Lithium Battery On / Off Switch
Ensure that the Lithium Battery Switch (S2) is set to the ON position.
3. S3 - Line Level Switch
Ensure that the Line Level Switch (S3) is set to the required line levels. These are
stated on the installation information sheet for the Outstation. Table 5 shows
switch settings corresponding to the different levels. Switch S3 is a 6-way DIL
switch. Switch positions 1 to 4 set the Output Power and switch positions 5 and 6
set the Receive Threshold.
