1.2 Physical Overview
The CS-105 features a case design which is symmetrical in nature, meaning that it can be mounted or
oriented in just about any way you could possibly need to, even vertically! TCS does advise against having
any obstruction on the vented sides of the case in order to allow for passive air flow, however. We will be
referring to these vented sides as Side A and Side B, since what the “back” and “front” are are up to you.
Side A features: 1) Single RJ-11 jack 2) Tactile push button 3) Single red LED.
Side B features: 1) Green 3-pin connector with detachable screw terminal 2) Black 2-pin connector with
detachable screw terminal 3) DC Power input jack 4) Dual RJ-45 LCC connector with four LEDs
The purpose of the LEDs is described in detail in the section below.
