2. DC socket terminal layout
Connector (Socket) : HEC0470-01-630 (Hosiden)
Polarity:
∗ Use terminal numbers 22, 23 or 26 as the signal ground for RS-232C.
∗ Short terminal numbers 25 and 26 to feed the paper.
∗ SEL LED lights up at the time on-line by connecting it to terminal numbers 27 and 28.
∗ Paper near end sensor:
∗ Supply of the power through the interface connector terminals is available, instead of the DC
socket terminal.
into V+ and V-pins. (To avoid voltage drops.)
This printer does not have the paper near end function. However, this function can be
built in by mounting a device such as a photo sensor.
NEAR_A: Pull up it with +4.75 to +5.1 V through the current limit resistance.
NEAR_OUT: The logic of NEAR_C is inversed and output.
Example:
The following diagram describes how a device such as a photo sensor is mounted to
use.
5V
When supplying the power through the DC socket, be sure to leave V+
and V- unconnected. Never supply the power into V+ and V- terminals,
and never short V+ and V- terminals.
When supplying the power through the interface and power connector
terminals, do not connect the DC socket.
