DUAL SERIAL INTERFACE KIT
The Serial Interface Board adds two serial communication ports
("uart2:" and "uart3:") to the standard serial communication port
("uart1:").
The printer's software detects when a Serial Interface Board is
installed and adds communication and buffer setup options for the
two additional communication ports.
When a Serial Interface Board is fitted, the following types of
interfaces become available:
"uart1:"
Fittedonprinter'sCPUboard.
RS232C Standard.
RS422or20mACL Option.Additionalcircuits required.
"uart2:"
FittedonSerial Interface Board.
RS232C
"uart3:"

RS232C or 20 mA CL Selectedbymeans of strap.
The Dual Serial Interface Kit consists of:
• 1 Serial interface board assy.
• 2 Screws MRX-Z 3 ×6 FZB (not intended for EasyCoder 501/
601)

❑Remove the existing cover plate.
❑Make sure that the CPU board is strapped and equipped for the
desired type of communication on "uart1:" (see the EasyCoder
501 or EasyCoder 601 Technical Manual). Once the interface

❑FittherequiredstrapsontheSerialInterfaceBoardasdescribed
on page 5.
❑Connect the cable from the interface board to connector P-4 at
the bottom rear corner of the CPU board. Be careful so the
interface board and the CPU board do not come in contact with
eachother,whichpossiblymaycausedamageorshort-circuiting.
❑Fit the interface board assembly to the printer's rear plate from

Straps
Thefollowing straps areusedto set upthedesired type ofinterface
on the communication ports "uart2:" and "uart3:".
Communication Port "uart2:"
There are no straps for controlling the RS 232C interface on
"uart2:".
Communication Port "uart3:"
RS 232C:
StrapfittedonP-3betweenpin1–2(rightandmiddlepins)selects
RS 232C.
20 mA Current Loop:
Strap fitted on P-3 between pin 2 – 3 (middle and left pins) selects
20 mA current loop.
External +5V:
External +5V (max. 200 mA) can be made available on pin 16 by
fitting a strap on P-6.
Be careful not to enable this option unintentionally, which may
cause harm to the connected terminal, computer or other device.
