3 Switch settings MA- The MA- can through different switch settings be adapted to a variety of running conditions. To set the switches, open the plastic case by placing and turning a screw-driver between top and bottom at the rear of the case. Danger!

6 Hints MA- are compatible with all asyncronous Westermo modem. The RS- interface on the MA- is configured as DCE (Data Communication Equipment). Most printers, PC s and terminals are set as DTE (Data Terminal Equipment). Some recommendation of cable configurations are given below. If any problems do occur on set up of the MA-, the LED s will be helpful. PWR: The unit has power. RD: Data received on line interface. TD: Data received on RS- interface. DCD: Carrier indication, must be on for transmission. RTS: Indicates the carrier control status. A good way to check the MA- is to carry out a loop back test. Connect T+ to R+ and T to R. Connect the RS- port to a terminal. When keys are pressed on the terminal you should receive the echo on screen. The TD & RD lights will both flicker simultaneously as you press the keys.
