EasyCoder 401/501/601 – Installation Instructions PARALLEL INTERFACE KIT Introduction Note: Illustrations show an EasyCoder 501. The principles for fitting this optional equipment in an EasyCoder 401 or 601 are exactly the same.

The Parallel Interface Board adds one parallel communication port ("centronics:") to the standard serial communication port ("uart1:"). Parallel communication is widely used for one-way communication between a computer and a single printer. As opposed to serial interfaces, the parallel interface requires no setup in the printer in regard of communication or buffers. 0

When a Parallel Interface Board is fitted, the following types of interfaces become available: "uart1:" RS 232C RS 422 or 20 mA CL

Fitted on printer's CPU board. Standard. Option. Additional circuits required.

"centronics:" Fitted on Parallel Interface Board. Centronics parallel interface only.

The Parallel Interface Kit consists of: 1 Interface board assy. 2 Screws (not intended for EasyCoder 401/501/601) Installation Instructions

Warning! Be careful not to enable the external +5V unintentionally, which may cause harm to the terminal, computer, or other device connected to this port!

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 401, 501 or 601 Technical Manual). Once the interface board has been fitted, it will be difficult to access the rear part of the CPU board. ❑

If a +5V line (max. 200 mA) is desired on the parallel port, fit a jumper on P-2 on the Parallel Interface Board. Continued! 3

❑

Select type of BUSY signal by means of straps on S-1 and S-2/S-3: • S-1: Strap = BUSY signal is on until end of ACK signal. No strap = ACK after BUSY signal (i.e., compatible to previous versions of this board). • S-2/S-3 (a jumper must be fitted on either S-2 or S-3): S-2 = BUSY signal on falling edge of /STROBE signal (i.e., according to specifications). S-3 = BUSY signal on rising edge of /STROBE signal (i.e., compatible to previous versions of this board).

❑

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 each other, which possibly may cause damage or short-circuiting.

❑

Fit the interface board assembly to the printer's rear plate from the inside as illustrated below using the same screws that held the removed cover plate.

❑

Reassemble the printer in reverse order. ❑ Connect the parallel communication cable to the Centronics connector. Please refer to page 5 for pinout descriptions. ❑

Connect the power cord and turn on the power.

Note: The PE signal (Paper End) on pin 12 requires an error-trapping routine to be included in the UBI Fingerprint software, activating the BUSY and READY statements. Here is an example on how such a routine may be written: 10 IF (PRSTAT AND 4) THEN GOSUB 1000 20 IF (PRSTAT AND 4) = 0 THEN GOSUB 2000 . . . . . . . . . . . . 1000 BUSY4 1010 RETURN 2000 READY4 2010 RETURN
