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 
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.
