(physical mounting location is flexible).

c. Third PCB: Signaling Distribution PCB (Required).

i. Securely attached to rear panel.

ii. Provide 16 DB25M connectors for distribution to RCE CMS CDVs

iii. If second PCB is not implemented, TX/RX status LED circuitry for each serial port.

iv. Provide TX and RX status LEDs adjacent to each physical serial port.

1. Green for TX.

2. Blue for RX.

3. Equal intensity and easily viewable both from 45° above LEDs horizontal axis and horizontal axis.

4. Located to left of respective serial port when viewed from exterior of enclosure.

v. Serial ports’ layout must be in 4 columns with port numbering shown on enclosure for each serial port.

1. Viewed from outside of enclosure.

a. Top-to-bottom (left to right columns): Column 1 (far left): Ports 1-4; Column 2: Ports 5-8; Column 3: Ports 9-12; Column 4 (far right): Ports 13-16.

d. PCBs connected together and securely attached to the enclosure.

e. Interface Cable:

i. 1-meter USB cable, USB-A to USB-B must be provided for external use. It should come with each Edgeport (or equivalent) product.

2. Edgeport (or equivalent):

a. Serial ports (Qty 16): DB-9M

b. Edgeport (or equivalent) RS-232 DB9 pinout:

http://ftp1.digi.com/support/documentation/loopback.txt

DB-9M Function Abbreviation Pin #1 Data Carrier Detect CD Pin #2 Receive Data RD or RX or RXD Pin #3 Transmitted Data TD or TX or TXD Pin #4 Data Terminal Ready DTR Pin #5 Signal Ground GND Pin #6 Data Set Ready DSR Pin #7 Request To Send RTS Pin #8 Clear To Send CTS

c. RS-232 Signaling:

i. Each respective Edgeport (or equivalent) serial port’s TX output signal is conditioned, buffered and then routed to the output PCB with no internal crosstalk.

1. Conditioned Edgeport (or equivalent) serial ports’ loaded TX Vo-minimum magnitude: 8.5VDC. Reference below requirement on the power supply for serial port TX amperage loading.

ii. Each external input RX is pass-through to the respective Edgeport (or equivalent) serial port with internal buffering and no crosstalk.

iii. Serial pins used by Control RCE (CDV): TX, RX, Gnd.

iv. 9600bps is required to be fully functional:

1. No unacceptable noise. Acceptable level is to be determined during 1st article testing and system response.

2. Symmetrical above and below signal ground.

3. No crosstalk between any serial port to any other serial port.

3. Power supply:

a. 110VAC with Power ON indicator and 6-foot AC power cable provided.

i. Power ON indicator must be located on the front panel.

ii. Power switch may be located on the front panel.

iii. Power cord connection must be located on rear panel (lower right).

b. Serial port(s):

i. TX max loading: 1k-ohm (this is for qty 8 CDV RXs connected in parallel).

1. 12VDC signaling magnitude => For each TX output, the current capacity requirement is 12mA minimum.

2. For 16 Edgeport (or equivalent) Ports => 16 x 12mA = 192mA minimum total current requirement for 16 total serial TX ports.
