The reverse power trip point may be adjusted by a preset control inside the E2026 Combiner Unit. To
access this control, slide the E2026 forwards after removing its two front fixing screws, taking care not
to strain any leads connected to its rear. The preset control (marked ‘REV TRIP’) is at the rear left
hand side of the printed circuit board accessible through an aperture in the screen cover. Care must
be taken that none of the other four preset controls on the board are altered. Adjust the control anti-
clockwise until the output power reaches a maximum.
Note that if this preset control is ever advanced too far clockwise, this may cause a decrease in output
power with less than 13W reverse power, i.e. with a relatively good antenna system and with the
E2026 REV led still green.
2.3.4 Serial Remote Control Baud Rate Setting
The operating Baud rate and be viewed and changed if required, by pressing [MODE] on the E2023
Transmitter Control Unit continuously for about 3 seconds. The screen will then change to show the
present rate and the four 'soft' keys below can be used to select 2400, 4800, 9600 or 19200 Baud.
The screen will time out in about 3 seconds after entry or after the last press of one of the four soft
keys. Timeout is 'counted' down on the display. The Baud rate is held in non-volatile RAM and is error
checked at power-on-reset, defaulting to 9600 if any Baud rate store error found.
