MICROPRINT 45CXA

The MicroPrint 45CXA/CH interface converter allows parallel printers with Centronics parallel interfaces to be used with the IEEE-488 (HP-IB/GPIB) bus. The device supports the IEEE-488 subsets: SHO, AHI, TO, TEO, L1, LEO, SRO, RLO, PPO, DCO, DTO, and CO.

The MicroPrint 45CXA/CH is an interface converter, not a printer emulator. Your software must send the correct data format to the MicroPrint and printer. Consult your computer or software manual to ensure the printer you wish to use is supported before connecting the MicroPrint.

The input connector is a 24 pin IEEE-488 female "D" connector with metric screw lock hardware. The output connector is a female 25 pin "DB25" type connector with screw lock hardware. The pinout of the parallel port is compatible with the IBM PC-type parallel printer interface cable. The MicroPrint 45CXA is powered by a ETL/CSA rated 9 VAC wall-mounted power adapter.

The MicroPrint 45CXA/CH is a one-way converter: from HP-IB to Parallel. DO NOT ATTEMPT TO USE IT IN THE OPPOSITE DIRECTION (i.e., with the MicroPrint 45CXA Centronics output connected to a computer parallel output port).

1) Set the MicroPrint 45CXA/CH to the correct HP-IB address. The MicroPrint is set at the factory for a listen address of 1 . To change the address, set the switch on the side of the MicroPrint for the desired HP-IB address or for "listen always". (Refer to the ADDRESS SWITCH SETTINGS section of this manual.)

2) Attach the HP-IB cable from the computer/controller to the "HP-IB" connector on the MicroPrint. Attach the cable from the printer or other peripheral to the "Centronics" connector on the MicroPrint.

NOTE: Ensure that both connectors are on securely BEFORE tightening the retaining screws. The latter should screw into the connectors easily and be "finger tight."

3) Plug the wall mount power supply connector into the female connector located on the side of the MicroPrint. Plug the wall mount power supply into an AC outlet which will activate the red LED indicator next to the Centronics connector. The MicroPrint is now ready for use.

NOTE: Since the MicroPrint reads the address switch setting only during power-up, it is necessary to interrupt the DC input power to the MicroPrint after any change to the switch settings. Also, it is advisable to "power up" the MicroPrint 45CXA/CH after other devices on the HP-IB bus.

If no output is obtained on the printer, or the output is incorrect, after the MicroPrint 45CXA/CH is installed, check the following before calling your Intelligent Interfaces representative:

1) Check that the MicroPrint 45CXA/CH is connected to the "low speed" HP-IB output port on the computer.

2) Check that the MicroPrint 45CXA/CH and printer are set to the same HP-IB address.

3) Check that the MicroPrint is connected to the printer with a 25 pin male to 36 pin male parallel printer cable(see PRINTER CABLE/SIGNAL WIRING table below).

4) Ensure that all cable connections at the computer, MicroPrint, and printer are seated correctly and tight.

5) For HP-UX applications, use driver #21 (primitive 8 bit driver) with the MicroPrint. For HP RISC computers, use the INSTR0 "driver."

6) Check that your computer has a "driver" (software routine, usually listed in a set-up or configuration menu) that supports the printer you are using. The MicroPrint is an interface converter, not a printer emulator. The computer must be configured for the parallel printer with which it is to be used. A configuration error is usually evidenced by "stray" or strange characters being printed. Consult your software documentation to properly "set-up" your printer with your computer.

Positions 1 through 5 and position 7 of SW1 are set to "1", or ON, by rocking, the individual switch controls toward the 1 ("ON") position. Positions 6 & 8 of SW1 are not used. To set the MicroPrint to the Listen Always mode, turn Switch Position 7 ON. When Position 7 is on, the settings of the other switch positions are ignored by the MicroPrint.

NOTE: When Position 7 of the switch is in the "ALWAYS", or ON, position, the MicroPrint accepts all data on the bus regardless of the address to which the data is sent.

*Maximum data rate possible. Actual data throughput will vary depending on computer/controller hardware, software, and peripheral used.
