Test Bed Connectors
The CoBox-Micro test bed has four connectors: CON1 (Serial Port 1 or Channel 1), CON2
(TTL Interface), CON4 (Serial Port 2 or Channel 2), and CON3, which is a 5VDC power
supply connector.

a. "CON1 Serial Port (Channel) 1" is also designated as "A".
b. "CON4 Serial Port (Channel) 2" is also designated as "B".
Note:
CON3 is a PCB-mounted, center-positive 5VDC power supply
connector.
When J1 is closed, the input voltage required is 5 VDC (+ - 5%). When
open, input voltage is 6-9 VDC (nominal 6VDC). The 3-pin header
next to J1 is the second serial port.
