2.1 Installation Procedure
The ET100R Router Module is designed for installation into one of the following ETU/TTU series units:
ETU01, TTU01, ETU01-U, ETU01A, ETU02-MUX, or TTU02-MUX
1. Disconnect all power and signal lines from the unit.
2. Place the unit on a well lit work bench.
3. Loosen the two rear thumb screws and slide the PCBA assemble out the rear of the unit. (See Figure 2-2)
4. If there is already an ETU/TTU module in the unit, remove the rear face cover (if applicable) and the three screws
that secure the module to the unit. Pull up the connector header end and remove the module.
5. Before installing the ET100R module, check to be sure the header pins are straight and not bent.
6. Install the module by placing the connector end (serial DIN, RJ-45 Ethernet connector) into the rear panel's chassis
hole from the inside. (See Figure 2-3)
7. Align the header pins with the socket on the main PCB assembly. (See Figure 2-4)
8. Seat the module in the header until the module rests on the main PCBA's standoffs.
9. Install the three holding screws for the module and tighten moderately tight, but do not over tighten. (See Figure 2-5)
10. From the rear of the unit, align the beauty plate with the LEDs, connectors and reset switch.
11. Use the two flat-head screws to secure the beauty plate. (See Figure 2-6)
12. Return the PCBA to the housing of the ETU/TTU unit, seating it fully and retightening the two rear panel thumb
