U/R/T200 series

Black * - Minus supply voltage (Ground) *
Red * + Plus supply voltage *
* Supply voltage is not present on RS422 connector on switch. Supply voltage must be from external
power supply. (Reason is that the FS200 series of switches can operate on up to 60VDC, while the
Acutime 2000 requires 24VDC power supply). The Acutime can also be powered from the same power
source as the switch via the power plug if the switch is powered from external 24VDC.
See tables below for more details about signal routing.
Table 1 shows the pin-out of the T200 GPS interface connector, and table 2 shows the pin-
out of the Acutime 2000.
