1. Interface
EZL-90 is a daughter board which supplies 3.3V power to EZL-80c and
an interface of RS232 to the EZL-80c.
1.1. DC Input (JP5)
DC5V is required to EZL-90 and the specification is below:
EZL-90 supplies 3.3V to the EZL-80c after regulating.

DTR and DSR can be loop backed with a DTR/DSR loopback jumper (JP6).
See the below section for more information.
1.3. DTR/DSR loopback jumper (JP6)
Some devices require DSR signal (DTR in terms of EZL-90). The devices
recognize the counterpart serial device with DSR. To get DSR signal from
the counterpart serial device, the counterpart serial devices have to
signal DTR.
EZL-90 has no DTR signal, but it has DTR/DSR loopback jumper. If user
set the jumper, EZL-90 returns its DSR signal from user device to DTR
so that user device recognizes the EZL-90.
