APOLLO user manual
IrDA/ASK-IR
An infrared port is available which supports the following infrared standards:
•
Infrared Data Association (IrDA) V1.0 SIR with baud rates to 115.2k/bps.
•
SHARP ASK-IR protocol with maximum baud rate up to 57.6k/bps.
For connector details, see page 36.
Enabling the infrared port prevents operation of Serial Port B (COM2). The
infrared port should be disconnected before using the COM2 port.
The following diagram shows the connection of the IrDA interface port J26 to a Sharp
GP2W0004YP IrDA transceiver module for IrDA 1.0 compliant data transmission.
Parallel port
The APOLLO provides a parallel port that can be used to connect an external printer,
tape drive, disk drive, scanner etc., or can provide additional digital I/O capability.
The port is both IBM XT/AT and IEEE1284 compatible. It supports Standard Parallel Port
(SPP), Enhanced Parallel Port (EPP) and Extended Capabilities Port (ECP) modes and
is compliant with the IEEE1284 specification. It also incorporates ChiProtect circuitry,
which prevents possible damage to the parallel port due to printer power-up.
For connector details, see page 37. Configuration of the parallel port operating mode is
performed in the I/O Device Configuration menu in the BIOS; see page
