SIO-Mode: Data Transfer Cable CE-T800 and CE-T801
The data transfer cables CE-T800 and CE-T801 are RS-232 level converters with an
integrated null-modem wiring. They can be used to connect the PC-G850V(S) to a
personal computer (PC) or other devices.
With these cables you can transfer data, program source-code or machine language
programs from or to a PC by using the TEXT/Sio-submenue or the SIO-commands (R,
W) of the integrated hex-monitor (MON). The DB-25 plug of the cable can be connected
directly to a PC (if necessary via a DB-9 adaptor), when there is a physical COM port.
Alternatively it can be connected to a USB-port through an additional serial-to-USB
adaptor. Don't use a null-modem adaptor or wiring for a PC-connection (because it's
already integrated in the cable).
However if a peripheral RS-232 device like the 4-color plotter CE-515P shall be
connected, a null-modem adaptor/wiring is mandatory in order to compensate the
integrated one.
On the CE-T800 pins 6 and 20 are not connected, pin 11 is not connected on both
models (CE-T800 and CE-T801).
Attention: Never touch the pins of the DB-25 plug. Static electricity may be harmful for the
circuits.
A free working area of about 300bytes is required for data transfer from a PC.
