1. Introduction
Measruing systems with a synchronous serial interface (SSI) cannot be simultaneously connected to
two separat controllers, both needing the position value. DIGICON makes it possible to transmit
(copying the position values) the data of the measuring system to two controllers (e.g. our digital cam
controllers and a PLC).
Features:
-
Supply voltage: 24V DC ±20%
Power absorption: 200mA in lost motion
For SSI signals up to 25BIT
Listening Mode
or optionally with incrmental in- or output
Cycle time < 1 ms
Transmitter level SSI: RS422
Connections: IP20 standard screw-pins
Assembly: clip-on assembly on symmetrical carrier rail according to EN 50 022, row assembly
Cover type: cover corresponds with IP20
Operating temperature: 0°C to + 55° C
Weight: about 500g

2. Assembly
The device is snapped onto the "EN carrier rail" in the switchboard (see chapter "4. Dimensions" on
page 4). The grounding pins and the cable mantling have to be put on the shortest way possible onto a
serial grounding pin next to the device. Through the grounded assembly board and its electrical
connection to the EN carrier rail, the disturbances are optimally grounded onto the cover. All cable
connections have to be realized in a cold state! Use double-wired, shielded connection cable only. Do
not lay the cable paralel to high tension power cables. If possible, lay shieldings to both sides.
3. Operation
Connect DIGICON to the measuring system and the controller according to the pin allocation. See also
chapter 5. Pin allocation on page 5. After activation DIGICON receives its voltage supply, and it, in
turn, supplies the measuring system. Which of the controllers is activated first does not matter, since
both currents are connected throug diodes in the DIGICON. DIGICON has an activation delay of about
10 sec, during witch the SSI output gives non-defined signals. Connected devices (e.g. PLC) have to
consider this !
3.1. Status LED
The status LED announces after approx.. 10 seconds ready status by continuous lights. Is the LED off
or flashes, the device has no power or is defective.
4. Dimensions
The following carrier rails can be used for the assembly of the cover:
NS 35 / 7.5 (DIN 50022)
NS 35 / 15 (DIN 50022)
NS 32 (DIN 50035)

6. DIP Switch configuration
DIGICON can be configured for many different applications through the DIP switch of the device.
To change the DIP switch setting, you have to open the device. You can open the cover in the center
with a screwdriver.
Attention:
Please take care not to damage the board or the other devices with the screwdriver.
DIP switch
The factory setting (default): switch 1 - 3 = OFF and 4 = ON.
6.1. DIP Switch 1 + 2 (Clock frequency)
DIP Switch 1
OFF
ON
OFF
ON
DIP Switch 2
OFF
OFF
ON
ON
Clock
576 KHz Clock (default)
288 KHz Clock
144 KHz Clock
external Clock at pins 4 & 5 (max. 600 KHz).
DIGICON does not create the clock for the measuring system, if both DIP switches are set to ON, but it
transmitts the Clock signal on pins 4 and 5 to pins 34 and 35. This synchronizes the data of the SSI
output 1 to the data of the SSI input.
6.2. DIP Switch 3 (Listening mode)
If this DIP switch is set to ON, DIGICON produces no own Clock signals, but triggers upon an xternal
Clock signal (listening) (max. 600 KHz) on pins 34 and 35. This makes it possible to send the data of
the SSI interface to two further devices (default = OFF).
6.3. DIP Switch 4 (Error Bit)
If this DIP switch is set to ON, DIGICON generates an SSI error at the SSI outputs, as soon as an error
is detected on the SSI input (default = ON). Is the DIP switch set to OFF, the data on the SSI outputs is
frozenuntil the error at the SSI input has been corrected.
Note:
This DIP - Switch must with single turn - encoders and/or Measuring systems with less
than 25 SSI - Bits become switched OFF, there the SSI - error bit in the software is fix on
bit 26.
