A brief overview of the front and rear panel controls and connections.

UPMAX ISC Front Panel

UPMAX ISC front panel features include:

Reset button for restarting the unit from the front panel (1A)
Four status LEDs indicating the status of each power supply (1B, 1C) the overall status of the unit (1D), and sync for the reference clock (1E).
A color LCD display to show status and basic configuration parameters (1F)
A five-button navigation cluster with Left, Right, Up, and Down arrows plus a green “OK” button (1G)
A USB port used for software updates (1H)

Basic configuration and status monitoring can be performed using the front panel controls as outlined in the Installation and Initial Setup Using the Front Panel Interface section. Connecting to UPMAX ISC via the web-based user interface -covered in the Remote User Interface section - provides easier navigation and full control of the unit.

UPMAX ISC Rear Panel

The rear panel of the UPMAX ISC contains the following connections:

Two RJ-45 Gigabit Ethernet connections, one for network remote control (2A) and one for AES67 I/O (2B)
Two independent 3Gb/s HD/SD-SDI inputs and outputs (2C) on female BNC connectors
Quad-Link SDI or MADI I/O (2D) - optional
Five AES-3 I/O connections (2E) on female BNC connectors
Parallel GPI/O control port (female DB-15) for five inputs and five outputs (2F)
Two IEC power inlets for the redundant internal universal auto-ranging power supplies (2G)

SDI I/O

Two sets of 3Gb/S HD/SD-SDI inputs and outputs are included. At this time, however, only the connectors closest to the RJ-45 Ethernet connectors are active. The second SDI connection will be enabled in an upcoming firmware update.

AES-3 I/O

The top row of AES-3 connectors are inputs. The outputs comprise the bottom row. Connectors are arranged as follows:

1/2 = Left/Right (L/R)
3/4 = Center/LFE (C/LFE)
5/6 = Left Surround/Right Surround (Ls/Rs)
7/8 = Left Front Height/Right Front Height (Tfl/Tfr)
9/10 = Left Rear Height/Right Rear Height (Tbl/Tbr)

GPI/O

The active state for GPI is Low and is internally pulled up through a 10K ohm resistor. The active state for GPO is Low and is current-limited through a 33-ohm resistor.

The pinout for the DB-15 sub-connector is as follows:

Pin Number	Function	Comment
1	+5v
2	GPI In 1	Active Low
3	GPI In 2	Active Low
4	GPI In 3	Active Low
5	GPI In 4	Active Low
6	GPI In 5	Active Low
7	GND
8	GND
9	+5v
10	GPO Out 1	Active Low
11	GPO Out 2	Active Low
12	GPO Out 3	Active Low
13	GPO Out 4	Active Low
14	GPO Out 5	Active Low
15	Status OK	Active High
