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

Output For modifications, E-502-░-░-D can be configured with a jumper as
the output of the 2nd channel of the DAC (voltage output in the
range -5 ...+ 5 V).
For any modifications, the E-502 can be configured with a jumper as -
15V output of an external device, or as an additional AGND contact, or
as an unconnected contact of the connector (NC).

1 ... 32.
• For all modes must be connected to AGND (in differential mode - to
increase noise immunity). In the "with common ground" mode, the
connection to AGND is recommended to do on the signal source side.
• Operation voltage range ±1 V
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.
