INTERFACES, cont'd.
On the CPU board, check:
■ Opto-couplers must be fitted on IC-40 and IC-41. These are not
included as standard and must be ordered separately.
■ Jumper must be fitted on pin 2–3 (upper position) of P-15 to
select 20 mA current loop.
❑ RS 232C circuit fitted on IC-34 (standard) and jumper fitted on
P-10 are of no consequence.
P-12 External 5 Volt:
Jumper fitted connects +5V to pin 16. Warning! Max. 200 mA.
Be careful not to enable the external 5V unintentionally, which may
cause harm to the terminal, PC or other device connected to this
port!
Cable configuration:
The printer end of the connection cable should have a DB25 female
connector. The computer end of the cable depends on your type of
computer.
The printer's connector contains the following signals:
Pin 9 + 20 mA
Pin 10 – 20 mA
Pin 11 TXD +
Pin 12 TXD –
Pin 13 + 20 mA*
Pin 14 – 20 mA*
Pin 16 + 5V, 200 mA (if jumper fitted on P-12)
Pin 18 RXD +
Pin 25 RXD –
*. In case of printer being active receiver.
