Output For modifications, the L-502-░-░-D can be configured with a jumper
as the output of the 1st DAC channel (voltage output in the range -5 ...
+ 5 V).
For any modifications, the L-502 can be configured with a jumper as +
15V output of an external device, or as an additional AGND contact, or
as an unconnected pin contact.

Input Synchronization input 1, which can also act as an additional input to
the digital input.
Compatible with the output logic level of TTL/CMOS- cells with a
supply voltage of +2.5 V to +5 V. The input has an extended range of
maximum permissible voltages (± 10 V relative to GND).
The minimum rate of rise of the signal drop at the input DI_SYN1 is
not specified, since there is a Schmitt trigger on this input.
There is a software option to turn the 1k pull-up resistor to a high logic
level at this input.
The DI_SYN1 input does not bypass the external TTL source, even
when the power is off.
