UP-600, UP-700 (serv.man25). UP600-700 Service Manual - Sharp ECR Service Manual (repair manual). Page 49

The UP-600/700 does not have the mode switch. The procedure for
resetting MRS, SRV is different from that of conventional cash regis-
ters.
in the UP-600/700, MRS, SRV resetting is selected and executed by
the key which has bee depressed when the CKDC reset is released
to start the system.

(In the case of MRS, security is added by a key operation equivalent
to a pass word.)

The UP-600/700 can use up to 2 optional external drawers.

One port corresponds to one drawer. Theoretically, it is possible to
drive multiple drawers at the same time, but this processing must be
inhibited softwarewisely because of power supply capacity and driver
hardware factors. If a power failure is detected, the drawer solenoid
drive must be stopped as soon as possible.

The drawer solenoid drive time must controlled in the range of 40
ms to 50 ms by the timer.

The drawer open/close sense signal is input into the built-in port of
the CPU. the sense signal of an optional drawer sensor is also wired
ORed before inputting.

•

P33=1: Any of the drawers is open.

The LAN of the UP-600/700 uses as a protocol Ethernet, which sup-
ports TCP/IP.

The interface with the TCP/IP board is achieved through 2 interrupt
signals and dual-port RAM.

The decode of dual-port RAM is located in the following space:

DP-RAM: F20000H - F2FFFFH (max. 64 KB)

The interruption from the TCP/IP is allocated as follows:

EXINTO: INTSW (SLAVE WRITE interrupt) bit 6 of 00FF81H

EXINT1: INTSR (SLAVE READ interrupt) bit 0 of 00FF80H

<TCP/IP connector terminals>

Two standard RS232 channels are compatible with the ER-A5RS.
However, while the ER-A5RS uses the IRQ2 terminal of the CPU for
interruption of the RS232, the UP-600/700 cannot use the IRQ1 ter-
minal instead of it. (The IRQ2 terminal is used for IR as the SCK1
terminal.)
The standard RS232 is fixed to the logic channels 1 and 8. Use the
channels 2,  3, 4, 5, 6 and 7 for the ER-A5RS.

This paragraph describes MCR option (UP-E13MR) control defined
by UP-600/700 hardware architecture.
3 channels of the serial port (interchangeable with 8251) built in the
MPCA9 are used. 3 tracks of data are read simultaneously. Supports
the first and second tracks MCR of ISO. (UP-E13MR)
