- Connect the cabling
- Configure the Outstation using the Handset terminal
The items that need configuring include:
Output Power Level (Switch S3)
Receive Threshold
2 or 4 Wire Line Connection
600 Ω / High Impedance Line Termination
Instation Communications Method (Jumpers)
Baud Rate / Mode
Outstation Address
Number of Outstations on the Line (GNO)
Number of Control Bytes for all Outstations on the line (GCW)
Number of Reply Bytes for all Outstations on the line
Digital Inputs and Reply Bytes
Fault Flag and Data Displays
LMU Information
Additional Propagation Delay
Items (1) to (4) are configured using switches on the Outstation PCB as described
in section 3.2.2.3. These switches relate to telephone line communications via
modems.
Item (5) is configured using the jumpers on the daughter board fitted to OTUs that
require RS232 communications with the Instation – see section 3.2.2.4.
All other items are configured using the handset terminal.
The TC12 Family Tree part number is 667/DZ/22600/000. This shows the
structure of part numbers within the TC12 system. The top level part number for
the TC12 Free-standing OTU is 667/1/22670/000.
Drawing 667/GA/22670/000 shows the mechanical arrangement of the TC12 OTU.
The layout of the mechanical rack and the positions of the OTU PCB, power
supply and detector cards are shown.
Note 1:The 11" version of the rack will accept a maximum of four single
backplanes. The 19" version of the rack will accept up to 12 single
backplanes. The double backplane is now obsolete.
Note 2:If a TC12 OTU is to be fitted into Microsense pole mounted Pelican
controller then use kit 667/1/22945/000 that contains the brackets and
fixings required.

3.2.2 Configuring the Outstation PCB

Figure 18 and Figure 19 are diagrams of the two variants of Outstation PCB.
Figure 18 corresponds to a PCB that operates using a modem communications
link only. Figure 19 corresponds to a PCB that is capable of operating with a
modem or an RS232 communications link.
The position of the switches, connectors, fuses and status LEDs are shown.
Ensure that the correct variant of the PCB has been supplied.
