The ASE BCOM-USB is a USB Bus powered, two-channel serial RS-232 communication device that is being offered as a direct replacement for the ASE two-channel BCOM PCMCIA communication card. The PCMCIA slot has been discontinued on most new laptops. The two RS-232 ports support both Synchronous (bit protocol) and Asynchronous (byte protocol) communication. A set of RS-232 LED’s for each channel show TX, RX, RTS, CTS, and CD status. Connection to the PC is via a standard USB device cable. Both USB 2.0 and USB 1.1 standards are supported. A +5 VDC connector is included for powering the external ASE dual channel, Bell 202 modem.
Communication operates up to 56K baud for byte-oriented protocols and 2400 baud for bit-oriented protocols. The BCOM-USB is available with new ASE2000 Test Set purchases or as an upgrade option from existing ASE PCMCIA or dongle (USB or Parallel port) Test Sets. Prices for new ASE2000 Test Sets with the BCOM-USB device, models ASE2000-USB-M and ASE2000-USB-RS, are the same as for PCMCIA models ASE2000-PCM-M and ASE2000-PCM-RS. A user can upgrade from an existing PCMCIA or dongle Test Set and requires return of the current hardware (PCMCIA card or dongle). To upgrade to Version 2 of the ASE2000 is an additional fee. For upgrades, the BCOM USB device will be delivered with a license supporting operation for six-weeks from the date of shipment. This provides an overlap period where the BCOM-USB device can be installed and tested prior to return of the PCMCIA card or dongle. When the PCMCIA card or dongle is returned, an updated license will be provided to remove the time limitation and allow unlimited usage. BCOM-USB devices included with new ASE2000 orders will be configured with the unlimited use license.
The BCOM-USB device requires ASE2000 release 1.47, available for download from our web site. Support is not included in prior releases. The BCOM-USB hardware package includes a BCOM-USB device, a 3’ USB Type A to USB Type B device cable, two 6’ DB9F to DB25M RS232 Cables, and a power connector for the ASE Dual Channel Bell 202/V.23 modem.
Designed for both laptop and desktop computers, the ASE2000-COM utilizes standard PC COM ports and is suitable for users that require support for byte oriented protocols only. For applications requiring bit oriented protocol support, or bit and byte oriented protocol support, the ASE2000-PCM is required. There are four points to note with this option:
Only byte protocols are supported. PC COM ports support a maximum of 8 data bits and will not accommodate bit oriented protocols. (for example, DNP 3 testing, IEC 870-5-101 testing and Modbus testing can operate using the standard PC comm ports as they are byte oriented)
Test Set Monitor Mode operation requires two communication channels, as provided by the ASE I/O cards. One channel is used to monitor master station transmissions and the other monitors RTU transmissions. If the PC has two COM ports available, Monitor Mode can be used, however, most laptop computers come equipped with only one external COM port.
Modem timing properties (pre-transmission mark, post-transmission mark, and receiver squelch times) require ASE hardware and are not supported on the COM model.
The optional dual channel modem provides two Bell 202T compatible modem channels and can be used in conjunction the ASE2000-USB I/O device. The modem is powered through the supplied cable.
ASE offers the test set in kit form or as a packaged system. The test set kit consists of the appropriate I/O board, cables, adapters, software, and user’s guide. The packaged system consists of the test set kit integrated into a PC of the user’s choice.
