6.10.2 E-BOX CONTROLLER RY 1601/ RY 1917
The electronics boxes of the switcher family are equipped with controller RY 1601
or RY 1917. The p.c. boards are provided with two independent microcomputers
(master and slave) and some required switches, keys as well as diverse LEDs and
a status indicator. All indicating and adjusting elements are accordingly labelled on
the board.
Key RESET (T1) Microcomputer reset. Simultaneous resetting of the master and slave
computers.
Key TEST (Master T2)
Key TEST (Slave T3) If these keys are pressed when releasing the reset key, the microcom-
puter does not enter the normal operating program but the so-called
”Monitor” mode.
This is a minimal system which is operative in the EPROMs. For the
duration the microcomputer is in the monitor mode, the red Error LED
will flash.
This mode is intended for BTS-internal use only.
DIL switch SETUP Switch T77 for adjustment of device type and configuration. The re-
spective switch position is only inquired after a reset, i.e. a change of
the switch position becomes only effective after a reset.
The switch position can also be inquired at the service terminal with
the program selection ”V” (software version).
The switches have the following functions:
Switch Position
On = 1
Off = 0

LED POWER GOOD Voltage monitoring, lights as soon as the 5V supply voltage of the p.c.
board is high enough. Below this threshold, both microcomputers are
permanently kept in the reset mode.
LED RUN (Master G1)
LED RUN (Slave G9) ”Lamp of life” of the microcomputer, is switched on with each bus cycle
of CPU or LAN coprocessor. If these LEDs do not light, there will be
a fatal error (no bus activities).
