PHYSICAL DESCRIPTION: The Scout Plus PC, the internal model is a 4 by 6 inches large rather compact halfcard. It has a 16550 16 byte buffer. The compact size makes this modem a good choice for portable computers, or other uses where space is at premium. Scout Plus, external model On the 5 1/2 by 1 1/2 front panel are 10 LEDS: MR modem ready TR terminal ready AA auto answer EC error correction HS high speed RD receive data SD send data CD carrier detect CS clear to send (hardware flow control) OH off hook The body of the modem is manufactured out of sturdy grey plastic with a 5 1/2 by 8 1/2 footprint. The top shows some venting grills. The back carries these connectors from left to right: RS-232 DB25 female Two switches for forcing DCD on and test mode RJ11 phone RJ11 line 5 pin power connector ON/OFF SWITCH These power supplies are available: 110 Volts, 60 Hz, 12 W input, 9V, 1 A output, US style three pronged integrated power supply-plug. 185 to 240 Volts with US style three pronged plug 185 to 240 Volts with German style two pronged plug The bottom panel carries a sticker with key AT Commands and the data compression/error control commands. The FCC sticker says: Complies with Part 68 Rules. FCC IDENTIFICATION: GSX-USA 65928-FA-E, Ringer equivalence: .8 B FCC Class B approval is pending The EPROM version is also printed on the bottom on a small label in the rear. Now we take it apart and find these chips: Analog Devices ADSP-2101 chipset (2105 family) running at 13.8 MHz. Two ROMs with 1 Mbit and 512 kbit size. The first ROM stores the code for the digital signal processor (DSP) and the second for the separate microcontroller. The RS 232 drivers are 14C88/14C89. The board looks clean with no glitches or wire add-ons detectable. It was easy to reassemble with just four Phillips screws which are accessible from the bottom. 3. SOFTWARE The Scouts come with Qmodem data communications software on a 1.2 MB 5 1/4 floppy. The software is preregistered, which means prepaid and the owner merely has to send in the registration card provided to Mustang Software to get access to their technical support. The fax software is Delrina's WinFax Lite 2.0 and Delrina's DosFax Lite. Delrina's packages have been editors choice in a recent review of fax software in PC Magazine. The MacIntosh package is available now with the correct MacIntosh to modem cable which allows hardware handshake and Appletalk Remote Acess. The fax software is Smith's Microsoftware's QuickLink II/Fax. 4.
