feedthrus. Instead, rock the ECU box up and down, while gently pushing on its back,
until the connectors line up. Once the connectors are all lined up, push the box in the
rest of the way.
7. Once the ECU is in place, use the knobs on the back panel of the ECU box, to turn
the locking screws and lock the assembly in place. Do not over tighten! (Hand
tighten.)
8. ECU Power Connection:
Important : Do not power up the RGA at this time.
Standard ECU boxes must be connected to the external 24 VDC power supply. Insert
the 9 pin, Type D female cable connector into the ECU connector 24 VDC
@ 2.5A on the back panel of the ECU box.
Units with the optional built-in power module (Option 02) plug directly into an AC
outlet and require no extra power sources: Use the power entry module on the back
panel of the ECU box to power the RGA directly from an AC outlet. Use the three-
wire power cord provided by SRS to connect the RGA directly to a properly
grounded wall outlet.
9. ECU RS-232 connection: Use the straight through RS232 cable with 9-pin, type D
connectors to connect the computer (usually DTE) to the RGA. (If your computer
does not have an RS232 port, use a USB-to-RS232 or Ethernet-to-RS232 adapter.)
Insert the 9 pin, Type D male cable connector into the ECU connector marked:
RS232/DCE/28.8k on the back panel of the ECU box.
Insert the 9 pin Type D female cable connector into the RS232 port on the computer
(or serial adapter). Use the DB25 to DB9 connector adapter if the computer (or serial
adapter) has a 25 pin Type D connector.
